AM1I-A Failing to Boot
by Matt B 06 Jan '20

06 Jan '20

Hi, In the spirit of board report coverage, I pulled out the (used, but new to me) AM1I-A I have and spent a day or two trying to install the latest coreboot on it. The board boots fine under the stock bios, and returns to working order if flashed with my backup, but shows little signs of life with coreboot. Along the way I extracted and included the vgabios rom, as well as tried with a nivida card, so I'm pretty sure that's not it. I tried having it save the console output to flash, but that made the build fail. [1] Yesterday evening I noticed it was configured by default to use open-source init (and for some reason the build finishes without error), but as far as I know that doesn't exist for family 16h. Switching to BinaryPI causes the build to fail. [2] 3rd party blobs are cloned and enabled. I'm running an Athlon 5250, or something of that nature, with a couple of gigs of ram on one dimm. My current .config is [3]. Sincerely, -Matt [1] https://pastebin.com/FZEiCq8P [2] https://pastebin.com/Q30u7Lgs [3] https://pastebin.com/ufuq22i8

CompuLab Intense PC?
by Mogens Jensen 05 Jan '20

05 Jan '20

I have a CompuLab Intense PC that has not been patched for CVE-2017-8083 (no CloseMnf protection mechanism for write protection of flash memory regions), which should allow me to install coreboot without an external programmer according to https://www.coreboot.org/Board:compulab/intense_pc So far I have successfully compiled coreboot from master branch, with binary blobs extracted from stock firmware. 1. The coreboot toolchain is built with command 'make crossgcc-i386 CPUS=$(nproc)' as shown in the tutorial, but my system is x86-64 so should I have used 'make crossgcc-x64' instead? 2. As I'm not using an external programmer to flash coreboot, is it correct to run flashrom like this 'flashrom -w coreboot.rom -p internal'? or do I need to pass more arguments? 3. In my configuration, this option is set by default: CONFIG_UNLOCK_FLASH_REGIONS=y, just to be sure, this will allow me to flash all regions, including ME, again without an external programmer after coreboot is installed? Regards, Mogens Jensen

AMD fam15h / A88XM-E (F2A85-M) - fix for a Turtle RAM issue?
by Mike Banon 04 Jan '20

04 Jan '20

Sequel of a Turtle RAM issue [1] I had on fam16h AM1I-A : a pair of [2] modules crawls as 1333MHz CL9 on A88XM-E (F2A85-M clone) with A10-6700. That's despite a really similar pair [3], just 1600MHz CL9 and in a SO-DIMM shape, runs on its' top 1600MHz CL9 speed at Lenovo G505S with A10-5750M which is also fam15h. I hoped this Turtle RAM problem is isolated to fam16h (thought that fam16h AGESA was a bit immature at its' time of release), but seems it affects fam15h also! I tried making buildOpts.c of A88XM-E at [4] as similar as possible to a successful G505S, considering they are from the same fam15h family and hoping that my change [5] will force it running at least on 1600MHz - but didn't help. :( Consider installing those SO-DIMM modules with a SO-DIMM to DIMM adapter, but not sure it will change anything. Why AGESA memory training is such a crap on fam15h desktop, while working fine on fam15h laptop? My clumsy hacking of AGESA wasn't successful on fam16h AM1I-A - but maybe because I was trying to do that at the wrong places! So I really need your advice, where exactly are the critical AGESA source code places I should hack to force that "overclocking" ? Thank you very much in advance, wish you a Happy New Year ;-) [1] https://www.mail-archive.com/coreboot@coreboot.org/msg53845.html [2] Crucial Ballistix Tactical Series DDR3 1866MHz CL9 (PC3-14900 9-9-9-24) UDIMM 240-Pin modules, part number BLT8G3D1869DT1TX0 [3] Crucial Ballistix Sport Series DDR3 1600MHz CL9 (PC3L-12800 9-9-9-24) SO-DIMM 204-Pin modules, part number BLS2K8G3N169ES4 [4] https://review.coreboot.org/c/coreboot/+/30987 [5] https://pastebin.com/PKGUC0vf

Could someone with a Fam16 using integrated graphics test https://review.coreboot.org/c/coreboot/+/38056 and comment there whether it worked (still boots and display still shows)? -- - don't top post Mailing list etiquette: - trim quoted reply to only relevant portions - when possible, copy and paste text instead of screenshots
