NRF52832 FatFs "Disk initialization failed"

[bariserbay]

Hi,

I'm trying to run fatfs example in sdk. I only changed the spi pin numbers. What is wrong with that?

         ),

Here is RTT screen.

My schematic is;

CS-------------P0.08
MOSI----------P0.06
SCK-----------P0.05
MISO----------P0.00

Thanks..

Hi

Ok. I recommend (like @awneil suggests) you try this out with a development kit or something similar to narrow down the sources of the problem. If the example works using a development kit, there is likely an issue with your custom board. If it doesn't work using the DK, there's a software issue. This will give us a much better starting point to work from.

Best regards,

Simon
