Hi Amit, I'm trying to access an SD card/reader using SPI on a Raspberry Pi. I've had a little success - some of my cards work, some don't. I get errors from time to time, but they appear harmless. I seem to have cured a spurious timeout problem. I'm using pr_info() to dump debug messages into /var/log/syslog. Maybe we can compare notes and come up with a solution. Contact me off-list of you prefer. Cheers, Dave On Wed, Feb 01, 2017 at 05:46:34PM +0530, amit mahadik wrote: > Hi Jaehoon, > I tried the use_spi_crc=0 option too.
