[U-Boot] Rockchip RV1108 eMMC initialization fail
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

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

Did you try my patchset to add it?

Please give it a try.
I tried it, but the same error still occurs :/

How does the log look for an SD ? I suspect it's probably clock or pinmux that's broken.
The log for SD card is the same like the one I posted, when using mainline u-boot from Denx. When using u-boot from rockchip, the log is slightly different, but it is the same error. I will put that log here too as soon as I can.

Command 8 fails, which is the first command to which the card must respond. Thus, something is fundamentally wrong with the communication with the card.
I should also mention that, I put U-boot itself into SD card/eMMC, so when I start the board, it gets loaded into RAM from SD card/eMMC. But after it loads and I can interact with it, I cannot communicate with the memory card(using the 'mmc' set of commands).
I have managed to find a workaround on Rockchip MINI EVB RV1108 board, putting the kernel image into USB, which I have access to, through the 'usb' commands. After the kernel starts, the SD card gets recognized by the kernel, and I can load the root filesystem from the SD card. So the problem is, after U-boot starts, I cannot use the SD card to load the kernel.
But on my custom board, I dont have USB, and I have to use the eMMC all the way through.
Also, here is the U-boot log when it starts, so under the MMC field, my eMMC gets recognized:

I appreciate a lot for the help till now, Regards, Alex

You might have PIN conflicts. Try to disable the SPI NOR and GMAC to start.
I tried that, but the same error happens.
I saw that here in the first post:
http://u-boot.10912.n7.nabble.com/Rockchip-RV1108-eMMC-support-not-working-t...
in the U-boot log, GPLL is 384000000, where in my log is 1188000000.
Also, in the same post from above, what kind of MMC card is used?
And here is the U-boot log, when I enable debug in include/common.h just to put more information.

Our board has a very minimal dts, we removed a lot of the nodes while adding support for it. Something like this: http://termbin.com/gqyd
Give this a go and see if it helps.
