Hi, I am a bit stumped at the moment. I attached the files that use the main code.
In usbh_usr.c, the function "USBH_USR_ReadWriteFirmware(void)" is the ffucntion that attempts to open the file.
The line "if(f_open(&file, "0:g4_firmware.bin",FA_READ) == FR_OK)" is not returning true even though I have a bin file with that name.
f_open is in ff.c
It looks good to me? Does anyone see something wrong?
I am using Keil 5.18, and an STM32F2.
Thanks for you help,
