I am using the STM32MP157D-EV1 board.The starter package is currently installed in EMMC boot mode.the version is "ST OpenSTLinux - Weston - (A Yocto Project Based Distro) 4.0.4-openstlinux-5.15-yocto-kirkstone-mp1-v22.11.23 \n \l" .I need to install Ubuntu 18.04 on this board, but I don't know how. Do I have to delete the installed package now and install Ubuntu 18.04?Ah, I downloaded the ubuntu-18.04.6-desktop-amd64.iso file. I can use Windows 10 and Oracle virtualbox.I want to use Windows 10 if possible, but if it's impossible, I can also use Oracle virtualbox.

Hello, I have an application whereby we have one ST25R3916B connected to 8 different antennas through relays. We need to read each antenna but with about 5-10 seconds between. This should allow enough time to initialize each antenna including AAT. The question is how is the best way to do this with the RFAL? I'm using the Polling Demo as a starting point since that looked like the easiest. Is this the correct order of operations? Will this properly clear out any lower level state variables that should be cleared between the different antennas?Stop the IC, using rfalNfcDeactivate(RFAL_NFC_DEACTIVATE_IDLE)Pause rfalNfcWorker()<switch the antenna relay, and wait for it to settle>Do everything in demoIni(), includingrfalNfcInitialize()Configure the discParams, Next, do the stuff in state DEMO_ST_START_DISCOVERY, including:Deactivate again (???)rfalNfcDiscover with our discParamsNext, do everything in DEMO_ST_DISCOVERY to read the UUID of the tag and be done.

Hello,I am using STM32G030F6P6 in one of my projects. I am using STM32 CubeMx as my IDE.In the datasheet I can see that it has 64KB of flash. However IDE perceives this as 32KB and I can not upload my code. This is what I read from the console. Does anyone know how to fix this issue.ThanksMemory Programming ...Opening and parsing file: ST-LINK_GDB_server_a02624.srec File     : ST-LINK_GDB_server_a02624.srec Size     : 47.18 KB  Address    : 0x08000000 Erasing memory corresponding to segment 0:Error: Operation exceeds memory limits.

helloI am studying by purchasing the EVALSTPM32 Board and connecting it to a PC via USB to Serial.If you look at the datasheet of STPM32, you can use the SYN and SCS pins to request a reset operation when booting the chip.However, the EVALSTPM32 board cannot control SYN when looking at the USB to Serial connection.In addition, DSP_CR3 SW_RESET also exists in the STPM32 chip.Question 1. What is the difference between reset using SYN and SCS and SW_RESET during chip booting?Question 2. When using UART communication of STPM32, is there any problem if SYN and SCS are connected to VCC?thank you.

Hi,I have a USB host HID FS/LS on a nucleo board (also on definitive hardware this happens). It works with several keyboards (Logitech, Acer, china trades, ...).Today, I connected an HP slim keyboard 803181-071 SP provided with my computer and after reset it doesn't initititate the enumeration. Using a logical analyser I see that both lines DP+ and DM- go high after connecting the usb host and there are 3 to 4 pulses around 50us. I suspect whether this could be a "chirp" sequencie trying to connect to the USB FS/LS host. To fix it, I needed to add a short delay around 1~2ms inside the library function HAL_HCD_Connect_Callback(), to ignore those 3 or 4 short 50us pulses that take around 200us. Can this delay do any harm? Should this delay be already provided on the HAL USB library? To achieve this delay, HAL_Delay(2) can not be used because would be called inside the ISR HCD_Port_IRQHandler and will get blocked. I used a for to 20000 @ 120MHz to get 2ms.I'm using CubeIDE 1.11.0 and last

Hello,I'm currently facing an issue with a basic project to setup the SDMMC1 peripheral where the function HAL_SD_Init() fails. The issue is happening inside HAL_SD_Init(), in SD_PowerON(), where it always returns HAL_SD_ERROR_UNSUPPORTED_FEATURE. I'm using a custom board with the STM32H743XI MCU with an external clock of 26MHz and the STM32CubeH7_FW_H7_V1.11.0 package.Please find below a picture of the STM32CubeMX Clock configuration:Here is the code that setup the clock:void hw_port_clock_init(void) { hw_clock_system_clock_init(); hw_clock_init_peripheral_clocks(); } static void hw_clock_system_clock_init(void) { RCC_OscInitTypeDef RCC_OscInitStruct = { 0 }; RCC_ClkInitTypeDef RCC_ClkInitStruct = { 0 };   // Supply configuration update enable HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY);   // Configure the main internal regulator output voltage __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1); while(!__HAL_PWR_GET_FLAG(PWR_FLAG_VOSRDY)) { }   __

STM32H745 IWDG if it reaches downcounter 0x0000, it mentions that system reset is generated.Is there any way to reset only M7 just or M4 just core.Also Errata Mentions that AXI domain is locked when watchdog reset is limited to CPU1 or CPU2 only.  Is there any way to reset single core without issue.

Hello,I am working on an IoT security project, where a TPM like STSAFE-A110 is required for signature verification and data decryption. The latter fails with the mentioned chip and the static (non-ephemeral) private key.Setup:X-NUCLEO-SAFEA1 board (with STSAFE-A110 TPM), pairing doneB-U585I-IOT02A MCU boardWindows 10 PCTera TermSTM32CubeIDEI have successfully run the Establish_Secret demo project, it shows ephemeral key usage: As I need the TPM's private key to survive the power cycle, I replace the ephemeral slot with the static slot 1, also on StSafeA_GenerateKeyPair call: The call to StSafeA_EstablishKey then fails with code 17 (STSAFEA_UNSATISFIED_ACCESS_CONDITION): Why does it fail? The documentation for STSAFE A110 clearly states that this feature is supported for slot 1 (document dm00675324): Thanks.

Hello, I've a strange problem and I can't find the answer on internet.I'm transmitting a data from UART2 of my STM32 Blue pill. Its just one line :- HAL_UART_Transmit(&huart2, (uint8_t*)Tx_msg, sizeof(Tx_msg), 100);While using with ST-Link, it works.When i connect micro usb from my laptop to Bluepill, it also works and transmits the data,But when i connect micro usb from 5V charger/adapter to Bluepill, it doesn't work. Bluepill is powered because LED is glowing but data isn't transmitted.I tried with various chargers of different power, but it doesn't work.Am i missing something?

Hello,I apologize if the answer is obvious but I want to confirm my understanding for the STUSB4710 (USB-C PD controller). Section 4.1 of the datasheet mentions that the default values for the voltage and current settings, which require NO I2C programming. I can optionally choose to overwrite these values via an I2C interface if I want. So if I use the 7.1. configuration, this means that, with no additional MCU, EEPROM or any other NVM, I can achieve:5V, 3A (15W)9V, 3A (27W)12V, 3A (36W)15V, 3A (40W)20V, 2.25A (45W)Is this logic correct?

Hi I want to use an EMMC( INSIGNIS NSEC53K) with STM32F405 SDIO interface. STM32F405 manual says: "Full compliance wit MhultiMediaCard System Specification Version 4.2."the EMMCwe have chosen: INSIGNIS NSEC53K. Its datasheet says:"Compliant with eMMC Specification Ver. 4.4, 4.41, 4.5, 5.0"Are these 2 kompatibel with each other? Will this work? At the moment I reach transferstate, but before I spend more time on it, it would be nice to know if there will be major issues.Which stm32 SDIO/SDMMC interfaces have a MMC spec version >= 4.4? Thanks

Is there the STM32U575I-EV Evaluation Board schematic somewhere? I cannot find it...

I am trying to connect to a Polar HRM with a STM32WB55 Nucleo board by modifying the BLE_p2pClient example. I tested the example and it worked in connecting to another ST board. Then I modified the code to connect to the UUID of the HRM I got from the scan, changing SERVER_REMOTE_BDADDR putting the UUID in reverse order. In the scan, I was able to find the exposed services to check if the scan was a success and got the UUID and RSSI from there. When I ran aci_gap_create_connection to connect, it returned a BLE_STATUS_SUCCESS, but I did not get a HCI_LE_CONNECTION_COMPLETE_EVENT like I did when I successfully connected to another ST board. I messed around with the connection interval, slave latency and supervision timeout, but still couldnt get the device to connect. I also am not seeing the complete name in the advertising data when I scan with the STM board, but I know its being advertised by checking with with a phone app and other device names are showing up as well. I tried the sam

I encountered a problem with inconsistent internal structure and marking for the same part number.We only found a document with such a problem.But it isn't suitable for this time.The document was published in 2014. It only mentions "T" and "K". But we need to explain "T" and "P".The detail as attachment. If they are the same in function?PCN MMS-MMY/14/8508 - Dated 16 Jul 2014

Hi,I developed an application with the Nucleo card which embeds an STM32WL55JCI6 starting from the "Sigfox_PushButton" example.The program uses 60 kB of flash and 8 kB of RAM and therefore works under the STM32WL55JCI6 which embeds 256 kB of flash and 64 kB of RAM.I would like to pass the programme to a smaller and cheaper microcontroller, the STM32WLE5C8U6 (64kB flash, 20 kB RAM).So I imported the project from the new target under CubeMX, I only had to reassign the used pins.Unfortunately, the problem is that when I compile the program, I am no longer at 60 kB of flash but at 84 kB used and the program therefore does not pass on the microcontroller. When looking at the flash memory usage details, the STM32WLE5C8U6 seems to consume much more memory in each function.I don't understand why the program which is exactly the same has a different size from one target to another ? Also, does this mean that the STM32WLE5C8U6 is unusable with Sigfox ?I'm confused, thanks for your help,Steven

Hi,I am trying to have a DMA move one unit of data every time the timer finishes it's counting period. The DMA would be circular so it would continually do this. I am going to be moving from a buffer to the CCR register of a pwm output. I saw a HAL_TIM_PWM_Start_DMA function but this does not allow me to specify the DMA to be circular or whether the memory side is stored in bytes/words/etc. How would I go about triggering a DMA on every cycle of a timer with hal?

I have an STM32L100C-DISCO board (MB110B Rev. B) and I want to install the LSE crystal, which is not populated by default. I consulted the schematic in the UM1656 "user manual for the 32L100CDISCOVERY discovery kit". Crystal X3 has a part number of "MC306-G-06Q-32.768 (JFVNY)" on the schematic. I consulted the JFVNY datasheet. The footprint didn't look right, but I purchased some crystals anyways. Of course the crystals are much too small to solder to the pads on the board. What crystal should I purchase to match the X3 footprint on the MB110B discovery board?

I´m using the SPI1 via the alternative pins PB3-PB5 and I'm experiencing various issues. I have previously used the STM32F722 with somehow same CubeIDE setup and code and that works perfectly.I have made a simple test application that only sends one byte via. HAL_SPI_Transmit.When setting a high baud rate (20M) it seems to work ok. This is too high for my design and baud rate is lowered. When monitoring the SPI clk. not all clk. cycles are transmitted. Lowering the baud rate even more results in no clk. cycles being transmitted.Any idea and thanks in advance...
