DRAM:Timeout initialising DRAM

[tbalthazar]

Hi,

I'm trying too boot my Lime 1.
I tried flashing the focal minimal and buster minimal images I found here on 2 different SD card (1 brand new, 1 older), using Etcher.
I connected the serial cable and I'm using screen to try to understand what's happening.

With the 2 cards and 2 images, I get the same error message:

Code Select Expand

U-Boot SPL 2021.04+olimex-1-20210821.121541 (Aug 21 2021 - 12:16:45 +0000)
DRAM:Timeout initialising DRAM

resetting ...
Any idea what it means?
Thanks.
Regards,
Thomas.

What exactly are:

1) the board;

2) the board variant;

3) the hardware revision, as printed on the board?

I tested here, the latest A10 boards seem to work fine with these images. Maybe you have older revision that experiences some issues with these images.

Thanks for your answer. I didn't realize there were different revisions of the Lime 1.
It looks like mine is a A10 Rev E, with an A20 Dual-Core T (F610BA 6763) CPU. I bought it in January 2016.
Here's a picture of the board:


Are some older images available somewhere?

You posted in "A10" sub-forum but you have "A20" board. Your board is A20-OLinuXino-LIME, hardware revision E.

Can you send me the initial start up log (I need to know how the board gets recognized by the image which is printed at start; upload the log somewhere and post the link here)? Maybe you would need to configure the image manually, set the exact board version and revision in the U-boot via tools we have provided. This is explained in chapter 7 "U-boot tools") in this document:

The same document contains more information about where you can download images. Let me know if something is not clear.
