Hi, I am trying to use eMMC as a storage medium for my custom board based on Rockchip RV1108.
I have already made the changes as described in this thread:
http://u-boot.10912.n7.nabble.com/Rockchip-RV1108-eMMC-support-not-working-t...
about using eMMC with RV1108.
When U-boot starts, and I try to access the eMMC, here is what I get:
=> mmc info CMD_SEND:0 ARG 0x00000000 MMC_RSP_NONE CMD_SEND:8 ARG 0x000001AA RET -110 CMD_SEND:55 ARG 0x00000000 RET -110 CMD_SEND:0 ARG 0x00000000 MMC_RSP_NONE CMD_SEND:1 ARG 0x00000000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:0 ARG 0x00000000 MMC_RSP_NONE CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0x003F8000 CMD_SEND:1 ARG 0x40300000 MMC_RSP_R3,4 0xC03F8000 CMD_SEND:2 ARG 0x00000000 MMC_RSP_R2 0x07FFFFFF 0xFFFFFFFF 0xFFFFFFFF 0xFFFFFFFF
DUMPING DATA 000 - 07 FF FF FF 004 - FF FF FF FF 008 - FF FF FF FF 012 - FF FF FF FF CMD_SEND:3 ARG 0x00010000 RET -110
So, as the last line says, I get Linux error code -110, which means "Connection timed out".
Here is info about the card I am using:
Flash Info: Manufacturer: SAMSUNG,value=00 Flash Size: 7457MB Block Size: 512KB Page Size: 2KB ECC Bits: 0 Access Time: 40 Flash CS: Flash<0>
I have also tried with different SD cards on Rockchip MINI EVB RV1108 board, but I get the same error.
I get the same error with U-boot from Rockchip, and mainline U-boot from Denx.
Any ideas?
Thanks, Alex
