Solved

Hi Guys,I need some help / input:I am trying to get the communication running between my Nucleo H7A3 and a Shield with a ISSI QuadSPI RAM in a SOP-8 Package running.Scenario:I am debugging with my Scope, I have a digital Probe on all 6 lines (CSn, Clock and DIO0-3) and I can see the communication.First issue:I am sending the command "0x05 - read mode register". I can see the outgoing communication on the scope, I can see the incoming communication on the scope. I can see on the scope that the RAM is sending a response - with the default Mode Register Value. But the Variable I am reading ins, is not updated with that value.My Code:  OSPI_RegularCmdTypeDef cmd = {0}; uint8_t buf[4] = {0,}; cmd.Instruction = SRAM_CMD_RDMR; // instruction byte cmd.InstructionMode = HAL_OSPI_INSTRUCTION_1_LINE; // mode of the instruction cmd.InstructionSize = HAL_OSPI_INSTRUCTION_8_BITS; // size of the instruction cmd.DataMode = HAL_OSPI_DATA_1_LINE; // data mode: 1 Li

Hi I was wondering the recommendation on dynamically loading containers a screen vs pre populating the screen with containers. Here is the situation, when the display loads up, is receives data from a controller. The screen for the display displays x amount of container A according to what the controller sent to the screen. This can be anywhere from 0-4 instances of the container. The user may also add/remove instances of the container. So now, according to this situation, I was thinking of dynamically populating the screen with x amount of container A. However. I am not sure whether this is recommended or not.The other option would be to put the max number of containers possible on the screen and make them invisible. Then only make x number visible once the screen loads. 

Good morning,we are trying to program a RVA15MD + NUCLEO-C071RB display. When loading the TouchGFX Demo 4 the programming is not successful (see errors in the attachment). While with the TouchGFX Demo 8 everything loads correctly and the demo works.Can anybody shows me a solution?This demo contains a circular slider, where can I find a similar circular slider that I can process?

Hello everyone,I am currently developing a GUI for the STM32F469I Discovery Board using the TouchGFX IDE. The GUI works perfectly when updated through the TouchGFX IDE.However, when I attempt to update the same project using STM32CubeIDE, I encounter a blank screen on the board. Interestingly, the GUI works fine if I do not modify the project name in the .cproject, .project, and TouchGFX project files.I followed the steps outlined in this video: https://www.youtube.com/watch?v=AizWAlbU4Og. But once I change the project name and import it into STM32CubeIDE, I only see a blank screen on the display.Could anyone suggest why this issue occurs after renaming the project and offer possible solutions to resolve it while changing the project name?Thank you in advance for your help!

IDE: STM32CubeIDE 1.17.0Board: NUCLEO-H7S3L8OS: Kubuntu 24.04 / Windows 10 I imported different example projects, but when I want to debug the project, I get this error"Failed to execute MI command:load /home/[User]/STM32CubeIDE/workspace_1.17.0/[Example]/STM32CubeIDE/Appli/Debug/[Example]_Appli.elf"(complete output below)I tried Linux Kubuntu 24.04 and Windows 10 (VirtualBox), the on board ST-Link v3 (JP1 open) and external ST-Link v3 (JP1 set). Then I created a new Project without any user code and it works.Next I tried an example project for NUCLEO-F446ZE (on board ST-Link v2-1) and it works fine, too. In addition, the example Project "LwIP_HTTP_Server_Raw" for H7S3L8 even caanot be imported. After pressing "Finish" the windows remains open with the error message "Fail to perform local copy" on top. With "Cancel", the example is not listed in the prject explorer, but is present on the file system (workspace). After this, the folder from the workspace can be impor

I see ST released long awaited Code for their bootloader compatible with STLINKV3+CubeProgr/CubeCLI...What about the Host side?, a STM32 hosting the bootloader process for another STM32, standalone.Any links or fingers pointing to people putting effort into this Bootloader Hosting stuff would be appreciated. 

Hi all,we are developing a board based on STM32F429 chip.In particular I'm developing a composite USB device on USB OTG port, showing a custom device + a CDC device [ep 0x85, 0x06, 0x83] using USB_Device_Library code.Windows correctly shows 3 items: a composite device, a generic USB device with my custom label/name, a virtual serial port (COM8).When I try to open the virtual port (by Putty) I see nothing on the terminal but if I inspect with Wireshark I see an infinite loop of BulkIN request, BulkIn response with XACT_ERROR, a RESET_PIPE_AND_CLEAR_STALL with both request end reply.I'n wondering why I have the XACT_ERROR on BulkIn request: I'm not able to find the point. I break-pointed some code in the HAL_PCD_IRQHandler() routine but it's hard to step in an interrupt handler.Very similar code (but compiled for STM32MP135 demo board) is working correctly.I'm focusing on USB_OTG_GINTSTS_IEPINT interrupt but which is the routine that replies to BulkIn?Maybe the PCD_WriteEm

In my system, I initialised two interrupts for wake-up from STOP2 mode, after exiting STOP2 mode, how do I know that the system is waking up by RTC timer or interrupt pin? Is there any variable that I can check after waking up to find the reason why the system is wake?

Hello Gang.I have STM32U5G9J-DK2 discovery kit.Latest software, TouchGFX and ...CubeI am NOOB and may be do something wrong but I do not see any mistakes from my side.I did small test project in the TouchGFXBut after uploading it to the kit I got : I did something wrong??? Thank U :)

I would like to use the WKUP 6 (RTC_WUT_S) to wake up from Standby mode. I am already using WKUP 7 with a pin so I need the RTC to be in safe mode.What would be the best way?

Hey,I am trying out the new RGB image compression in TGFX 4.24 and are having some issues. My program compiles fine without any compression.I have only turned the feature on in TouchGFX Designer and generated code. Is there something else I am missing?

Hello, I'm trying to debug an issue I'm having with the GPDMA on an STMu5. I believe I'm mostly there but for some reasons I'm missing only some DMA triggers. So the situation is as follows: I'm trying to read the IDR register of a GPIO port into memory using DMA that is sync to the rising edge of a PWM timer. Here is the situation: In white is the PWM signal and the last 4 channels are the GPIOs I'm trying to read. I have configured my DMA as follows: The trigger event Selection of the TIM15 is OC1REF. So like I said I believe I'm mostly there, here is a snippet of the DMA buffer: And here are the corresponding signals: so first of all DMA_buffer[0] is: 1000000100, the value that im looking for is GPIO 1 to 4 so the value is 0100 which correspond to the second rising edge of the clock. I have shown the buffer values to the signal in the picture of the logic analyser. DMA_buffer[1] is 1000. which is also good if we follow the logic analyser and finally DMA_buffer[2] is 0010. The L

Dear Team, We have selected STM32H733VGT6 (LQFP100) for our Project and trying to configure and design an ETHERNET (MII Mode) interface.While configuring it using CUBEMX,1) ETH_TXD2 is showing up on PC2_C Pin (No Alternative Pins Available).2)ETH_TX_CLK is showing up on PC3_C Pin (No Alternative Pins Available). On the other hand, In the Datasheet it says,The Above Functionalities are available on PC2 and PC3 Pins Respectively (Not on PC2_C and PC3_C). But the above Selected Controller has PC2_C and PC3_C Pins (PC2 and PC3 Pins are not available). 3) Adding to the Above Query, In the Ethernet Interface Characteristics section of the Data Sheet, it is mentioned as following:"Due to timing constraint Pxy_C I/Os cannot be used as ethernet signals" Can you please provide a Clarification on this as well. My Question is, can we still use available PC2_C and PC3_C for the above Functionalities. If not, what are the alternative ways in which we can achieve ab

Hello,I am wondering/unsure about the XSPIM in H/RS MCUs.I want to connect a quad-SPI NOR flash to an XSPI. Is the XSPIM needed at all?Let's say the XSPIM is in default configuration, i.e. EN bit in XSPIM_CR is 0.Does that mean that I can configure the XSPI like I would configure a QUADSPI peripheral?That is, I would configure GPIOs that the NOR flash is connected to (AF mode, speed, etc.).Then I would configure the XSPI CR, DCR and so on.Is that correct? Or do I need to configure the XSPIM (see Figure 194 in RM0477,rev7, therethe XPIM is present). Thanks!

Hi guysThis project here was built and debugged fine last week. Today, I get this message:'Launching has encounteres a problem.

What does a red highlight mean? I am able to select the pin for the function I want but I'm seeing at least two pins with of these red highlights. One is an GPIO output which toggles fine. The other is for an EXTI which no longer generates an interrupt when the signal transitions.   

Hello everyone,I am looking for middleware to control NAND flash using the STM32U535CE.The target device is the Macronix MX35LF4G24AD.I would like to perform page program/read, bad block management, and 8-bit ECC processing per 524 bytes. However, I cannot find middleware compatible with the STM32U535CE.Could you let me know if such middleware is available?Thanks and regardsKa_T

Hello, ST expertI'm using the STM32G0B1RCT6 and have enabled the LSECSSON. I've discovered a rather incredible phenomenon. I'm using a 3.3V battery for VBAT. When I disconnect the VDD of the MCU, it abnormally triggers the LSECSS fault. As a result, after disconnecting the VDD of the MCU, the system uses the LSI as the RTC clock. However, the LSI cannot operate in the VBAT voltage domain. Below is my log：« hello world! DR:[0x2101] TR:[0x00] BDCR:[0x00]DR:[0x2101] TR:[0x00] BDCR:[0x00]DR:[0x2101] TR:[0x00] BDCR:[0x00] not init backup domain!

Hi evryone, I'm trying to initialise a very basic UART communication between my stm32 L552ZE-Q and my computer by following this tutorial: https://www.youtube.com/watch?v=dEQwSl8mCFs&t=924s I have no errors, no warning while compiling and the problem is that there is nothing displayed on the PuTTy teminal. I also used TeraTerm and VScode serial terminal and nothing happened. I tried also on an other computer and same problem. I have upgraded the code by adding a blinking LED to verify if something is even running and the LED is blinking but again nothing on Putty...  while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ HAL_UART_Transmit(&huart2, tx_buffer, 27, 10); HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_9); HAL_Delay(1000); } I've checked the COM port used in my device manager and set the correct Baud rate, I don't know to do next. Thank you for your help! Louis

Hi, i can definitely use a push in the right direction as i am really stuck on this one. Goal is to push new firmware onto a STM32F446 via the built-in bootloader. For this i have connected two MCU's on a CAN bus, the receiving one is a STM32F446. I use CAN2 (see an2606 table 80) pin PB5 as RX and PB13 as TX.  Strange combination by the way. One if default and one is the alternate pin. Anyway.. Baudrate is set to 125kHz on both MCU's. I reset the STM32F446 with BOOT0 high so i get into the bootloader. On the sending side, i send out a can message with id 0x79 with one byte data, a 0x00. (documention states it does not matter what you send, so i thought to do one byte with just a zero)    This should trigger a response from the bootloader with a ACK, but it does not. I get nothing. What i see is that the target reboots after this message. I suspect becuase of a timeout or other error or so. It happens fast, so timeout is probably in a few ms or so. I have tried diffe

Hello,I would like to go a bit deep in the inductive wake up function. Unfortunatly seems that i will need to work with delta 1 at least for the moment, but due that it is a battery powered device i need to avoid as much as fake awake when there is no RFID card in front.1) Im playing with your 3916B Discovery kit connected to  my antena instead ST antena board, and im seeing for example that on phase awaken, mostly of the “fakes” are values under the reference, like i set as reference 120 and fake shows a value of 119, never 121. Is that realistic to say that fakes will follow that logic? Or it is just coincidence…2) Has ST any statistics about behaviour with Delta 1?3) In addition, my feeling is that Just rebooting sometimes the reference is taken for example as 120 and sometimes in a range of 140. i think im not modifying anything. Any idea about why this could be? I mean, is normal to read such different values as reference? Im using Discovery firmware, with no modification.4)

Following up on a diff post.  I have a strange result. If I call the GetSensorId for the VL53L1X we use today I get a return of decimal 61098 which is 0xEEAA.  However the comments in the code claim for the GetSensorId should be: "This function returns the sensor id, sensor Id must be 0xEEAC".  Which is inconsistent? What is even stranger is that the L4CD shows it should be 0xEEAA (which we have not even received yet). I'm perplexed now.    

Hello everyone,I'm sitting over here working on one of my projects and found that STM32CubeMX generated code with an error. My project uses the STM32H7R3L8H6H MCU with Ethernet activated in the connectivity. I have my project set to "generate individual files" because I like it more that way. However, the file "eth.c" contains an error at the beginning of the file: #if defined ( __ICCARM__ ) /*!< IAR Compiler */ #pragma location=0x24020000 ETH_DMADescTypeDef DMARxDscrTab[ETH_RX_DESC_CNT]; /* Ethernet Rx DMA Descriptors */ #pragma location=0x24020080 ETH_DMADescTypeDef DMATxDscrTab[ETH_TX_DESC_CNT]; /* Ethernet Tx DMA Descriptors */ #elif defined ( __CC_ARM ) /* MDK ARM Compiler */ __attribute__((at(0x24020000))) ETH_DMADescTypeDef DMARxDscrTab[ETH_RX_DESC_CNT]; /* Ethernet Rx DMA Descriptors */ __attribute__((at(0x24020080))) ETH_DMADescTypeDef DMATxDscrTab[ETH_TX_DESC_CNT]; /* Ethernet Tx DMA Descriptors */ #elif defined ( __GNUC__ ) || defined ( __ARMCC_VERSION )) /* GNU

Hello, I have a brand new STM32C0116-DK evaluation board (official) and I fear I just bricked the on-board ST-Link :\ I wanted to run an example (blink LED) from the CubeIDE provided examples. When I pressed run, a popup displayed to notify me the ST-Link firmware should be updated. So I launched the process but the popup window freezed. I closed CubeIDE and disconnected the USB cable... Now the ST-Link LED is blinking RED at about 0,5 Hz and Windows doesn't detect any USB device at all (nothing is enumerated in device manager, nor a "USB device not working properly" popup) I think I did a mistake...I will need it to work from home home for the two weeks. Is there a way I can force it to pass in update mode? I only have this board at hand right now, so is the only ST-Link debugger I have (had)...
