I'm experiencing issues with the sd_jpeg example included in the EVKB-IMXRT1050 SDK. The example will work on some SD cards and not others (different manufacturers and sometimes different capacities will behave differently), and sometimes erratically with a 'functional' SD card. Failure sometimes occurs in the MOUNT_SDCard() function during the last check:
// Open file to check
error = f_open(&jpgFil, _T("/000.jpg"), FA_OPEN_EXISTING);
if (error != FR_OK)
PRINTF("No demo jpeg file!\r\n");
This implies that the SD card is actually recognized and mounts properly, yet the relevant image files are not found. I am loading the program into SDRAM, and am able to step through the code using MCUXpresso.
Has anyone else experienced similar issues with the SD card and this example?
