[U-Boot] Rockchip RV1108 eMMC initialization fail

[U-Boot] Rockchip RV1108 eMMC initialization fail

[alex94]

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-td343843.html#a343866

about using eMMC with RV1108.

When U-boot starts, and I try to access the eMMC, here is what I get:

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.

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.

[U-Boot] Rockchip RV1108 eMMC initialization fail

[alex94]

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:

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-td343843.html#a343866

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.
