I believe the pxa_mmc_gen.c is what needs to be used. There is no other PXA MMC driver in U-Boot mainline. I now noticed it has some basic monahans (pxa3xx) support too.
Could you give out a log with MACRO CONFIG_MMC_TRACE on yourpxa27x device ? any initialize ,read ,write, erase operation?
Sorry for disturb you.No, I cannot, sorry. I don't have the PXA27x device handy.
Thanks , are you using SPI mode or SD mode with your SDXC card? This is Important.
SD mode.
In recently test, the mmc clock seemed didn't start successfully after stop mmc clock. if the function pxa_mmc_stop_clock was NOT used. the data sent to sdcard was corrupt. That's annoyed. Could you provide a way to solve the problem?
