STM32F103 "Device electronic signature" unreadable after USB init

I can usually read my STM32F103XB's "Device electronic signature" ("Flash size register" and "Unique device ID") both by "using the JTAG/SWD or the CPU", as per that quote from the RM0008 documentation. The correct addresses hold values of 0x0080 (in...

I am trying to use fatfs with STM32L496g. Whenever i call f_mount, i am getting res = 1, (A hard error occurred in the low level disk I/O driver). I am using a discovery board for now. The sample project that comes along with it, is working fine.

I have tried debugging, and the error comes wheneverf_mkfs -> find_volume-> checkfs -> move_window -> disk_write is called.looking at it, i see the implementation in diskio.cDRESULT disk_write ( BYTE pdrv, /* Physical drive nmuber to identify the d...

USART protocol in bootloader : behavior of readout unprotect

Hello,I have a small question about the bootloader, I guess this is common to all protocols but I have only tested with USART protocol. After sending the command readout unprotect, the application note states that :"After the transmission of the [fir...
