We came across a situation where an application code which is working for STM32H753 revision Y when moved to same MCU's revision V does not even go to the main.cpp.Sometimes if it manages to go to main.cpp it writes to I2C1 some values consistently ...
Hi.Im experiencing a race condition in SDMMC_CmdReadSingleBlock. (being called trough HAL_SD_ReadBlocks_DMA).SDMMC_CmdReadSingleBlock calls SDMMC_SendCommand in order to start transfer.Then it calls SDMMC_GetCmdResp1 to verify that transfer is starte...
Dear I try to porting the sample code (from STM32Cube_FW_F3_V1.11.0\Projects\STM32303E_EVAL\Examples\UART\UART_WakeUpFromStop) to my PCB board with STM32F303RC, but I can't wake up MCU from STOP by UART Is there anyone know whether the example code ...
I have multiple boards of STM32L476 board. In our application, we have OTA module in which we use dual bank feature.The OTA flow is like:1) Read data from SPI2) Write to Bank 2's pages in incremental order3) Once all data are transferred, go for flas...
Hello everyone,I am facing issues while performing Signal Integrity analysis using STM32h IBIS model.Currently i am analysing Signal Integrity for I2C signals where i am configuring my MCU I2C signal levels to 3.3V, but when simulated i am getting 2....
When connecting a parallel FLASH device to the micro the address mappings are thus:For a NOR FLASH device with an 8 bit data bus, the internal address (FMC_Ax) maps directly to the micro hardware pins (HW_Ax).8-Bit Data BusFMC_A0 => HW_A0 ======> FL_...
I am using STM32L4 discovery board and External QSPI to save data. From the datasheet, it is mentioned that before every write, erase command has to be issued. But when I issue Erase Block or Subblock command, complete Chip is getting erased. Can any...
Hello!. I Have two firmwares: bootloader and application. MCU is STM32L031K6U6First launched bootloader checking backdoor pin and launching appliction or starting firmware update process. If need just start firmware all work fine (bootloader don't ch...
Hello,I use DMA UART on Rx.but I get interrupts on half complete and full complete.is it possible to get interrupt earlier? when I get "\n" char?maybe the best way to mange is to use circular DMA, and when the half complete interrupt is fired, save t...
I am using an STM32G4. I want to output PWM from a timer channel on one pin (call it pin A) and have a GPIO output on another (pin B). Then I want to be able to switch the functions on the two pins so that pin A is now a GPIO output and pin B is the...
