Hello all,
I have some troubles to initialize the micro SD card with my custom board.
I have used the nRF 52 DK to write a basic code and do some test. For micro card SD with the nRF 52 DK I have used this micro card SD reader
Here you can find the basic code. With my custom board the code can not do the initialization function. As the result disk_state = disk_initialize(0); is always true.

and in the make file I have add the path to the file custom_board.h and I have changed the CFLAG like this
CFLAGS += -DBOARD_CUSTOM
# CFLAGS += -DBOARD_PCA10056
Do you have an idea why I can not initialize the micro SD card ?
When looking at the schematic if you find something strange with the antenna or related with the BLE you may have spotted another error as I can not connect to the BLE (but I am able to detect it ! ).
Thank you very much for the help. As you can understand when looking at the custom board schematic, I have spend a lot of time and energy on this project and I start to feel low when running in so complicated problem.
Best regards,
Loïc
