Any one tested with Strontium micro HCSD card? I followed the abobe suggestion. I am getting the error Storage init ERROR! GPIO Pins of nrf9160 used: CLK-29,MOSI-27,MISO-30,CS-26

I didn't get any error in fat_fs demo once the SPI buffer is assigned. I could mount the card and read the root folder structure.

Hi Zack,

[quote user="Zack Mak"]The solution to this problem is to set the "Size of RAM buffers for SPIM peripherals" to some number. If the size is set to 0, the SPI transceive function will always return error.[/quote]

Thank you for pointing that out. I was not aware of this as I have not been able to test with an SD card.

The customer writes that he still has issues, an error from disk_access_init(). Are you getting this as well?

Hi,

I fixed that problem and now able to access SD cards.

The "no GPIO device" message turns out unrelated to this issue at all. The CS pin is actually controlled by the SDHC_SPI driver, not the SPI driver.

The solution to this problem is to set the "Size of RAM buffers for SPIM peripherals" to some number. If the size is set to 0, the SPI transceive function will always return error.

Best regards,

Hi,

FYR

I added the CONFIG_GPIO=y to prj.conf and the error message is still there.

I also tried the hex file that you uploaded in another thread. The error message is still there.

Thanks

Hello,

I added the CONFIG_GPIO=y to prj.conf and that removed the "CS control inhibited (no GPIO device)" error on my side.

Have forwarded this to our NCS team, and will get back to you/customer ASAP.

Kind regards,
