Hi community!

Good news. I was able to port Coreboot on the motherboard asus m5a78l-m lx3. I took for the base source code of two projects - amd mahogany_fam10 and asus m4a785-m. I've added support for DDR3 and graphics core HD3000.
 
The results are shown below:

 

SeaBios 1.9

Windows 7 SP1

Ubuntu Linux 15.10

Memory 1600 2 Gb

Memory 1600 4 Gb

Now I have two problems that I can not solve:

1. Memtest86+ memory issues when testing the read / write errors occurs.
2. The problem with the amount of memory on Linux.
The above problems are also included in the projects - amd mahogany_fam10 and asus m4a785-m. These projects I tested the motherboard asus m4a785-m. Also on these issues was described here https://www.coreboot.org/Board:asus/m4a785-m and https://www.coreboot.org/Board:asus/m4a785t-m.
I would be grateful for any help.
Thank you!

I was able to start up the internal graphics core, but unfortunately only in text mode. I think the problem in the initialization in funcution - internal_gfx_pci_dev_init and rs780_internal_gfx_enable (src\southbridge\amd\rs780\gfx.c).
The lack of documentation does not give me the opportunity to properly install the necessary bits for gfx.
Thanks for any help.

Hi!

I need help to porting coreboot Asus M4a785m on Asus M5a78l-m lx3.

I'm trying to porting coreboot on the motherboard Asus M5a78l-m lx3 (rs780l/sb710). I cannot find documentation for the northbridge rs780l.

My configuration:  cpu - Athlon 2 x2 220 (K10), memory - 2 + 2 Gb DDR3, video - Asus GT520, sata segate hdd 500Gb, sata asus dvd-rw.

I have a positive result for the configuration with memory 2Gb and external video card Asus GT520. I can load Linux kernel 2.6.

But, i have two problems:

1. I cannot load coreboot with internal graphics card (hd 3000). Coreboot stops loading and to print on console "Calling option ROM…". May be the problems with gfx configuration?

2. I cannot run Linux with memory 4Gb. Coreboot is loading, SeaBios is loading too, but  Linux stop load on usb3-2 and ata1 setup. May be the problems with memory map?

Please, help me. I can provide all the necessary information from the log coreboot, SeaBios and Linux.

Thanks.
