Hi,

We have a custom board based on rv1108 evb where we are trying to add eMMC support.

Here are the changes we made so far:

With this change the eMMC driver is loaded:

U-Boot 2018.11-rc1-00097-ge89d583-dirty (Oct 08 2018 - 16:11:40 -0300)

Model: Rockchip RV1108 Evaluation board DRAM: 128 MiB APLL: 600000000 DPLL:1200000000 GPLL:384000000 MMC: dwmmc@30110000: 0 Loading Environment from MMC... *** Warning - bad CRC, using default environment

and we can also check the 'mmc info' command:

=> mmc info Device: dwmmc@30110000 Manufacturer ID: 70 OEM: 100 Name: M6270 Bus Speed: 52000000 Mode : MMC High Speed (52MHz) Rd Block Len: 512 MMC version 5.1 High Capacity: Yes Capacity: 3.5 GiB Bus Width: 8-bit Erase Group Size: 512 KiB HC WP Group Size: 8 MiB User Capacity: 3.5 GiB WRREL Boot Capacity: 2 MiB ENH RPMB Capacity: 512 KiB ENH

I don't have a 1108 board with emmc on my hand.

the mmc info show that the eMMC has been detected. So would try other mmc commands such as: mmc read/write ?

but we are not able to save the environment to the eMMC card:

=> saveenv Saving Environment to MMC... Writing to MMC(0)... failed Failed (1)

Maybe you need a deeper dig to find the point where the error happen

=>

Any ideas?
