Error to initialize the sdcard (disk_initialize)

You can set a flag, then later handle the data in your main loop, but if you do not want to do this you can change the SPI interrupt priority:

If you have copied most of the functions from example "fatfs", then you can change sdk_config.h::SPI_DEFAULT_CONFIG_IRQ_PRIORITY to '6'.

Hi Alseth,

Unfortunally I cant change the function call to main context because I need to write into sdcard when the the firmware receive a bluetooth message.

Summing up, I have some develop boards and when one board sends to another board, the board that received the bluetooth message must to save the message into sdcard.

How I can change the priority these interrupts or how I how I can to do to discovery which interrpt is preventing the firmware to write into sdcard?

Hi,

Are you calling this from an interrupt? If yes; then you are looping here because you're waiting for another interrupt, configured with lower or equal priority as the one you're in.

Could you try scheduling the function call to main context instead?

Best regards,
