Resolved! FDCAN ROM bootloader pins for stm32H743ZI
As discussed in here, im trying to use ST\s ROM bootloader, when i read AN2606 Page 280 shows the FDCAN1 rx and tx Pins Those pins dont exist in stm32H743ZI@KDJEM.1 proposed "you can activate the FDCAN bootloader with only by PH13/PH14 pins." What ...
STM32G474 IAP bin file transfer stopped according to AN4657
Hello,Now I am designing a IAP program for STM32G474VET6 according to the AN4657 referred to STM32L476G_EVAL. and I used VScode +CMake tools.I have modified the flash_if.h because of the diffrence between STM32G474VET6 and STM32L476G as below /* Def...
Mass erase operation failed! Please verify flash protection
We have made a batch of 30 boards using the STM32U073. One of this 30 boards is not working as expected.I am able to connect STM32CubeProgrammer to the processor using the SWD port. I am using STM32CubeProgrammer v2.18.0. If I try and erase the flash...
Resolved! FDCAN bootloader on UFBGA169 STM32H743AI
Hi,App note AN2606 says I should use FDCAN1_Rx pin PH14 (similary Tx pin) to be able to use FDCAN bootloader but selected package UFBGA169 doesn't have such pins.Can I use default FDCAN Pins to work with bootloader?
Resolved! HAL_SPI error is not reported even with failed cases in STML4 device
HAL_SPI_Transmit(&hspi1, NULL, 0, 0); uint32_t error = HAL_SPI_GetError(&hspi1); HAL_SPI_StateTypeDef spiState = HAL_SPI_GetState(&hspi1); above lines of code i expect error = error codespiState must be error state , but i still gets error&nbs...
Resolved! Synchronize DMA to GPIO transfer on 2 distant MCU by external signal.
Hello, community. I have a task to transfer a value from the buffer of 64 values in memory to 7 GPIO by DMA every 1us. I solved it by setting a TIM2 timer Channel1 to Output Compare mode and TRGO to Update event. Then, I mapped the DMA request to TIM...
How to configure RTC_WUT_S wake-up source of WKUP6 event on STM32U545?
Dear Sirs,I would like to wake-up the STM32U545 using a WKUP6 event and the RTC_WUT_S source event.I'm absolutely not an expert, and this is the first time that I try to wake-up the MCU.I have not found any information on how to set the RTC_WUT_S reg...
STM32 UART does not receive first byte
MCU: STM32L476RGT6Hello,I am using UART to read data from the NEO-M9N GPS receiver. My receive buffer stores all received data besides the first byte:This forum states to add a delay between initializing UART and sending data, and this forum states t...
Resolved! STM32N6 boot application >64kB from external QSPI
Hi,I'm adapting the NUCLEO-N657X0-Q template "Template_FSBL_LRUN" to boot a tested application from the QSPIUnfourtunately, as soon as the binary becomes larger than 64kB and uses a second sector, the application will not boot anymore.I can reproduce...
