Sorry for the long delay, we are currently short on staff during summer break and you may experience delayed answers.

This ticket may help you to get an understanding of how to use an SD card with NCS and nRF9160.

Best regards,

Simon

So, I ran thru a debug session and found the assert you were mentioning. It does fire off from the fatfs_mount and I get a -5, which maps to FR_NO_PATH. I don't really understand what this error means tho. Is it expecting the SD card to be partitioned and have a directory called SD on it?

Thanks

Have you tried to debug your code and figure out why it's asserting. I guess the reason is due to the assert in ncs\v1.3.0\zephyr\subsys\fs\fat_fs.c→fatfs_mount(). If that fails, the chip will reset.

If fatfs_mount() fails, you should make sure you've connected the SD card correctly and also debug the function. If the mentioned assert is firing, then you could check what res is equal to, to get an indication of why it's failing.
