Hi, marek
I've seen on the Internet that pxa310 support SDHC up to 32GB, butI'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 particularprocess 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 theMultiMediaCard 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.
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 .
