question on SMM
by ron minnich 30 Jun '17

30 Jun '17

there's something I am certain I don't understand about SMM on intel chipsets. The question is pretty simple. Consider a system with a recent intel chipset and flash. Is there some special secret sauce that disables writing to flash unless in SMM and if so, what is it? Thanks to anyone who can point me to chapter and verse of a data sheet. ron

Coreboot make script do not use custom, seabiosconfig file.
by Rostislav Okulov 29 Jun '17

29 Jun '17

I made my own seabios config file (.seabiosconfig) and put it in root coreboot directory. Add it in configuration like this CONFIG_PAYLOAD_CONFIGFILE="~/coreboot/.seabiosconfig" Next I do ~/coreboot> make to build coreboot but .seabiosconfig file skipped by make script and default file used instead (/coreboot/payloads/external/SeaBIOS/seabios/.config) How to properly add my custom seabios config file?

Hi Mike, Sorry, my last answer was very short. As M2N-E has a RS232 port, I am using cutecom on another computer connected through RS232/serial/com port. You could use a USB/RS232 too. Best regards.

PC Engines APU2: ASM1061 and mPCIe 2 slot
by Kamil Wcislo 28 Jun '17

28 Jun '17

Hi all, We've been investigating lately the issue with ASM1061 on the APU2 board, because it often turns up in different discussions. Problem is, that the mPCIe 2 slot on APU2 platform is not working the same as mPCIe 1 slot. Controller is not detected, and even if it is, the machine enters boot loop (after some disk is physically connected).I've pinpointed the location of the machine reset to AHCI port detect routines in SeaBIOS. I've made some notes about my investigation here: https://github.com/pcengines/apu2-documentation/blob/master/docs/debug/mpci… WLAN cards, as far as I know, work without major problems. The one difference between the slots is that mPCIe 2 is actually using PCI express channel dedicated to graphic card (so is using the root complex in north bridge), whereas mPCIe 1 is using PCI express root complex from the south bridge. Does anybody have any insights, where could I look further to investigate this issue, because I'm stuck at the moment? -- Best regards, Kamil Wcisło Embedded Systems Engineer http://3mdeb.com | @3mdeb_com

Re: [coreboot] coreboot Digest, Vol 147, Issue 19
by Keith Hui 28 Jun '17

28 Jun '17

Hi (again) coreboot: I read the below from the digest. Having brought the P2B-LS into coreboot along with RAM init to 440BX northbridge and cache init to Slot 1 CPUs back in 2010, I am interested in bringing this platform up to standard. Where can I read up on this cbmem in romstage standard? However, of the family I only have P2B-LS and P3B-F on hand to boot test. I just checked out the master from git in case they are part of the readings.

Hi Idwer, Thanks for the info. After adding changes, I can able to build coreboot with iPXE. After flashing coreboot.rom, still ethernet is not working (Ethernet port's LED is not blinking). Actually, My broad has Broadcom Ethernet controller. Is there any specific setting have to do for Broadcom in Coreboot's menuconfig. HW Details, CPU: Intel Rageley CPU. Mother Board: Accton AS7512X_32 Switch IC: Cavium.

X201 poweroff and suspend to RAM status?
by Marek Behun 27 Jun '17

27 Jun '17

Hello all, the last time I tried coreboot on X201 (2 months ago) there were some problems with powering the device off and also with suspend to RAM. These problems are also somehow mentioned on wiki in Issues. I would like to ask if someone has an idea how to try to fix this issues. I can do C programming and am willing to experiment on my X201, but do not know what exactly should I try and how... Thank you. Marek
