Solved

My program writes to flash but needs to know if it has been run before since the chip was re-programmed. I've set up a section in the flash memory that gets written to by the programFLASH2 (rx) : ORIGIN = 0x08100000, LENGTH = 1024K .option : { . = ALIGN(4); _s_my_option = .; *(.my_option) . = ALIGN(4) ; _e_my_option = .; } >FLASH2This appears as expected in the load map.I've then setup an array in this section in the main programconst char initoptions[256]__attribute__ ((section (".option"))) ={0xFF};but this doesn't appear in the map and is not getting written when I reflash the chip.What am I missing?Thanks

Hi all ! I am mainly working on Linux with GNU toolchain. It works well except for graphics programming as TouchGFX works only on Windows.I would like to know if someone find a solution to this problem. But perhaps everybody works on Windows ... I will appreciate your experience feedback.For info, I have tested the new Qt demo for the STM32F769i Discovery board. It works well. But, as no source code is provided, I am not sure it fits my build chain.Thanks,Olivier

I use stm32cubemx try to create a usb pd project, but usb pd can't be choosed.stm32g431rbtx.​

HelloI've been working on a project on an nucleo F411RE and everythings been going fine.I then had to port the project to nucleo H743ZI.As i am using the DMA i had to change the ram from DTCRAM to RAM_D1.Before the change to RAM_D1 i could have strings greater than 15 chars, e.g.std::string test("12345678901234567890");Would not crash my program.After changing to RAM_D1 the program would get to the string and then go directly to the void _exit (int status) loop.Anyone have any ideas what might be the problem ?

I bought B-G474E-DPOW1 and had one typec interface, which cc connect ucpd_dbcc pins. I need another typec interface to send pd message, could I use the ucpd_cc pins for this? And I try to change the demo code "USB-PD_Consumer_1port", set USBPD_PORT_COUNT=2, while got error when pd init, error in USBPD_PE_Init. /* PE SET UP : Port 0 */ CHECK_PE_FUNCTION_CALL(USBPD_PE_Init(USBPD_PORT_0, (USBPD_SettingsTypeDef *)&DPM_Settings[USBPD_PORT_0], &DPM_Params[USBPD_PORT_0], &dpmCallbacks)); #if USBPD_PORT_COUNT == 2

I have connected the nucleo board to my PC using micro usb cable but when I press degugging button in Keil uVision5 it shows "Internal Command error".How to enable debugging in Nucleo board?

That question started bothering me when I was struggling with TLE493D that started interrupting using the i2c clock line.It looked like the i2c in the F429 was gone bananas and keeping the i2c stuck (busy).I was thinking of feeding the i2c the clock pulses and maybe end condition by writing to the GPIO data registers (bit banging), but would that be seen by the i2c? It's not clear from the pictures in the reference manual.It looks (in the pictures) like at least a pin acts as a pin for alternate function, GPIO input and analog input at the same time. And I can read back (GPIO input) the GPIO output pin state.Maybe I can even use ADC to measure the pin's GPIO output voltage? Or get a GPIO input while also measuring the input signal voltage with ADC?I guess, though, that only one "party" can drive the pin output at a time?Oh, and I'm talking about these pictures: https://bluetechs.files.wordpress.com/2013/12/115.png

I'm developing a custom board with STM32WB55CGU6 with firmware based on Cable Replacement example. Trying changing the advertised name, I can not put more than 5 chars, the BLE stops working. I know the standard advertising supports until 7 chars. What I have to configure to have a bigger advertised name ?

Hello,I would like to signal a possible error on the reference manual of the STM32L496 (RM0351 Rev 6)At pag 348, section 11.4.5, Table 45 the first line (source port 8bit, destination port 8bit) indicates that the Number of data items to transfer is 8, however I think it should be 4.Moreover: I don't clearly understand the description of the NDT register. It is described as "the number of data items to transfer", however it looks more like as "the number of DMA transfer". In fact, regardless the sizes of data (MSIZE, PSIZE) the NDT is decremented after every DMA transfer, being it 32,16 or 8 bit. Then for me the fact that it refers to the number of data items is misleading.

I have a weird problem. I have the Nucleo board with a TLE493 magnetometer connected. When I connect the USB cable (power the system), file manager opens. If I then close the window, upload my SW using Atollic, my magnetometer code works fine, but if I don't use the debugger, initialization of TLE fails - the I2C HW is already "busy". (TLE starts interrupting via the I2C clock line).What's different in the boots? The boot0-pin is low by default, and it hasn't been touched.What code initializes the USB and what else does it do? I'm using I2C2 with PF1 as the clock line.

Following up on my last question about the LTDC interface (That's now working) I'm working through the app note 4861.Where for the LTDC interface there is a nice walkthrough on how to find the timing values there is nothing like that for the SDRAM selection. bummer.I have made a board with AS4C4M16SA for the SDRAM, datasheet here: https://www.alliancememory.com/wp-content/uploads/pdf/dram/64M-AS4C4M16SA-CI_v3.0_March%202015.pdfThe timing information is on page 20.But the app note states that one can either use the CubeMX interface or use the BSP files.it goes (lightly) over the BSP integration but don't mention the CubeMX at all.More specifically I am looking for a way to figure out the timing setup from the datasheet:Those are the value for the SDRAM supplied with the STM32F746G-DISCO board.. is there any pointers on how to adjust these values for a new chip?Also - since I'm running the TouchGFX integration I have a file called 'HW_Init.cpp' In the top there is a couple of definitions

Hi,I have an application of which uses the STM32F469NI with two MX25L12833F QSPI flash in dual flash mode and are encountering an issue when using HAL_QSPI_AutoPolling().CLK is configured at 1MHz (to allow for logic analyser), both devices share the same CLK and nCS lines, where nCS is provided from BK2_nCS.When performing a sector erase, the instruction is sent to both chips as outlined in AN4760 section 2.2.4, the peripheral is then configured to auto poll for the WEL and WIP bits to be reset. I am seeing that it does not respect both chips. The device on QSPI1 can finish and the autopoll stops yet the device on QSPI2 continues the erase operation. See attached snippet from a logic analyser where device 1 is CH2-5 and device 2 is CH6-9.Is this expected behaviour or is extra configuration required for autopolling when using Dual Flash mode?Thanks,Jack

Hello and thank you for your help ahead of time.I am working on a vehicle detection product using the LIS2MDL and noticed a strange anomaly with the Z-axis when I was testing for stability over temperature. Showm in the attached photo, the Z-axis randomly become very noisy until i moved a piece of ferrous metal near the sensor, at which point it stopped. It was only the z-axis too, all others remained very stable as can be seen in the graph. It should also be noted that this behavior was rare and doesn't happen every time im evaluating the stability. This behavior is very undesirable if it would happen randomly on the final product.Any idea on what could be causing this? Could the Pin 5 Capacitor trace length cause this? Any ideas are greatly appreciated.Thanks again for your help.

My M24LR04E Discovery Board is not showing up when using the CR95HF Development Software's "Auto Detect tool" or the "Vicinity Tags - NDEF Message user interface" tool. In these tools the tag just doesnt show up as seen when you scan for tags. In the "Tag Detection tool" however, the tool is shown (however this isnt very usefull, it only shows that its a ISO15693 tag). The M24LR04E Board itself still has the functionalities to show the voltage of the field or to show the temperature sensor output. The NDEF message however reads:"NOT A NDEF TEXT MESSAGE"How this (probably) happened:I was playing around with the discovery board for my internship, to get to know NFC. I have installed the CR95HF Development Software that goes along with the M24LR04E Discovery Kit.When playing around with the Vicinity Tags - NDEF Message user interface, I could read and write away NDEF messages to the M24LR04E Discovery Board.After that I opened this program: the ISO15693 User Interface M24LR04E. Here I sta

Hello All,I have used STM32F103RBTx Dev board previously on Windows (windows 7 Professional) Platform with Kiel uVision4 IDE and STM32CubeMX 4.24 tool.I had also build an example code which used PWM, GPIO, UART and SPI peripherals and it worked properly.As per requirement now i have to use Ubuntu 14.04 Linux based system with Atollic TrueSTUDIO® for STM32, Version: 9.2.0 and STM32 CubeMX version 5.3.0.I have Installed Atollic IDE and STM32CubeMX and also installed Embedded Software package for STM32F in CubeMx, reference Image attached belowAfter this by refering the video on the link given below i tried to build the blinky example code,https://www.youtube.com/watch?v=6RqUkFIeN6w&t=470sHowever I was able generate the code but when i compile the code i am getting error mention in the attached screen shoot.So is there any Dev board specific package installation to be done so that it finds the HAL Library path which is mentioned in error messageOr, I am missing out on something while

Hi,I have made a PCB with ST25R3911B. Regarding the matching network and the antenna, I have design them starting from the X-NUCLEO NFC05A1 evaluation board (the antenna is the same).The firmware on the microcontroller works, because we have tested it with the X-NUCLEO NFC05A1 mounted over NUCLEO F072RB (the microcontroller is the same STM32F072RB and the pinout is the same).Unfortunately the custom board is not working properly: the IRQ pin is always high (we are using wake up mode for phase/amplitude). In AN4985 there are images of the RF output signal, that are the same that I am obtaining on the X-NUCLEO NFC05A1. Unfortunately on my custom PCB it seems there is not an RF output signal.In the attached images you can see the voltage value at pin 11 of ST25R3911B (RFIO2), I have an RF output on the EV board, but on my custom board the voltage level is Always at 5V. The voltage at power supply pin is correct, as well as the crystal oscillation frequency.There must be an hardw

As per the section 5.2.3 of the STM32H747I-DISCO board user manual, the default configuration of the hardware is to use SMPS mode but the default mode generated by STM32CubeMX when you select STM32H747I-DISCO board is LDO. Because of this mismatch, the board is bricked.ST should have used the same power supply configuration in both the hardware board and default CubeMX configuration.

Hello Community, Is there a fast way to clear the EEPROM of ST25DV. for example, a fast API to clear the whole EEPROM, and how long it will take? I want to have the option to clear the memory when a special command is written through RF Thank you very much for your help

Hi,I'm working with the STM32H750VBTx and I switched to the latest FW version package, STM32Cube FW_H7 V1.3.2.CubeMX generated the stm32f7xx_hal_conf.h file and a line was added to this file:#ifdef HAL_EXTI_MODULE_ENABLED #include "stm32f7xx_hal_exti.h" #endif /* HAL_EXTI_MODULE_ENABLED */The EXTI flags are all enabled in the CubeMX.The stm32f7xx_hal_exti.h file does not exist and so a fatal error is generated: stm32h7xx_hal_exti.h: No such file or directoryIs there a new version of FW H7-package?Do you know this problem?

As described in your help center, I configure my canvasBuffer in my main.cpp. As I have a quite important requirement, I put it in a specific section of my internal RAM memory.However, the designer seems to override this in all my viewBase files with a 3600 buffer size, and not in my reserved section anymore of course, which is a problem. In the designer, when a screen is selected, on the right, there is an option to overwrite the canvasBuffer (quite new option ? I do not really remember it). However, those option are unchecked on all screens, and still defined in the viewBase files.Is there any way to avoid that and keep using my dedicated memory located region for it ?

Is it possible to override a ScrollList so that list scrolling is controlled by a separate widget? This separate widget is on the same screen as the ScrollList, but is outside of the ScrollList. I would still like to be able to use normal press & release on the Items inside the ScrollList.In other words, I do not want to allow the user to scroll the ScrollList by dragging on the ScrollList itself.If that is possible, exactly what would need to be overridden to accomplish that?

Hi,Having tested all the examples from the STM32F7 package for the STM32F769 Discovery kit, I started to write my own project from scratch. For thios, the starting point is the STMCubeMX tool.So far, everything went well till I reached the point of the LCD. I cannot get it working. I compared the generated code with the one of the BSP. It is similar except inthe initialization sequencethe value of some configured timings, that STMCubeMX does not allow to set as in the BSPHas anyone any experience and advices to get a LCD working from a STMCubeMX project ?Thanks in advance.Regards.

I'm using both SPI1 and SPI2 on an STM32G071RBT Nucleo board, using STM32CubeIDE code generation and LL interface. Both SPIs are configured to use DMA for receive and transmit. SPI1 uses channels 2 & 3; SPI2 uses channels 4 & 5. The DMA transmit complete interrupt is enabled on the receive channels. (2 & 4).SPI1 works fine, but not SPI2!?!?! The SPI transaction is successfully started, and the data sent, but I never receive the channel 4 transfer complete interrupt. Any thoughts? Does the DMAMUX need to be configured to receive a channel 4 interrupt? (The interrupt handler is called "DMA1_Ch4_7_DMAMUX1_OVR_IRQHandler".)Thanks for any help.
