Hi,I am currently developping a custom bootloader to flash my app with STM32H7A3ZIx / SDMMC / FATFS with DMA templateIt fetch a binary (*.bin) from an SD card, read maximum BUFFER_SIZE (=8192) and stores it in a uint8_t RAM_Buf[BUFFER_SIZE] array (8K...
OTG_FS_IRQHandler is endlessly called"signal handler called>() at 0xffffffe9"I have already increase the heap and stack size to 0x2000. I use the STM32H753i-EVAL2 board
Hello!Almost everything is in the title. Is there a way to rename the device I'm developing.When I lsusb, it says STMicroelectronics virtual COM port. How do I change that toMyDeviceName?Beside this, is there a need to get a vendor ID / product ID? I...
