it's an ARM. There was a primitive memory test in the early days of our ARM ports that might be useful. It was simple but it caught our problems.

How about MemTest86? See this link http://www.coreboot.org/Memtest86, I never use it before.

How to check if DRAM init is OK?

Hi, I'm now porting coreboot to CubieTruck, a development board with an Allwinner A20 SoC. I use Mr.Nuke's code[1] and Allwinner's user manual for reference.However, when I modified the code and tested with the board, the console gave only two lines of message and it get stuck. So I thought DRAM init failed. I put some printks at bootblock_media.c, and found the bug occurs at line 118[2], which showed the access of a certain memory space caused the error. So I need to know how to check if the DRAM init works. Thanks Iru Cai [1] https://github.com/mrnuke/coreboot/tree/cubie_mmc [2] https://github.com/mrnuke/coreboot/blob/cubie_mmc/src/cpu/allwinner/a10/boo…

The ADL855PC is an embedded module that is using the i855GME chipset (the same as the Getac W130 as far as I remember). Last I checked, the 855 port was not very good, but there's probably nothing in the way of attempting to write a port for that laptop. You should make sure you have some means of recovering your flash chip back to something working, because writing a port and getting a system booting typically takes a few tries ;) Stefan

i855GM on laptop - possible or not?
by Andrey Korolyov Aug. 2, 2015

Aug. 2, 2015

Hello, I am trying to estimate amount of effort to make an old military Getac to work with coreboot (currently it runs Insyde with computrace-style code). All currently supported boards, lanner/em8510 and digitallogic/adl855pc are desktops, which means that I should play with EC support almost from scratch. Given the fact that i855G(M) was quite popular in P-M era, are there any real issues standing behind lack of support of a simular mobile platform in a tree? Thanks in advance!
