Hi, marek
I've seen on the Internet that pxa310 support SDHC up to 32GB,
but
I'm using u-boot 2014.01, It could initialize OK.
Device: PXA MMC
Manufacturer ID: 3
OEM: 5344
Name: SS08G
Tran Speed: 26000000
Rd Block Len: 512
SD version 3.0
High Capacity: Yes
Capacity: 7.4 GiB
Bus Width: 4-bit
It shows time out while reading block . Is there any particular
process should be add?
It is well possible that the driver is broken on PXA3xx . Note that
mainline U- Boot doesn't really support PXA3xx . Are you working on
PXA3xx support for mainline U-Boot ?
I'm looking for support for pxa310 MMC SDHC .
In the PXA310 SPEC:
The MMC module is based on the standards outlined in the
MultiMediaCard System
Specification Version 3.3.1. The SD module manages one SD or SDIO card
based on the standards
outlined in the SD Memory Card Specification Version 1.10 and SDIO Card
Specification Version
1.0
I'm doubting if the controller support SDHC (SD 2.0) ?
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.
Also, you didn't really answer my question with regards to porting U-Boot
above. If you do that, use latest mainline, not 2014.01 .
I just have to add SD support for my board, It's emergency. sorry for
that.
Hmmm.
Best regards,
Marek Vasut
