The PXA27x controller works even with SDXC , that is tested. I
suspect there might be some change in the PXA3xx controller, but I
don't really know for sure. You'd have to check.
Thank you for your answer. are you using SD mode or SPI Mode? which
version are you using?
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 your
pxa27x 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?
