Re: [coreboot] No VGA output on e350m1 after flashing. what to do?

Hi! On 30.06.2013 19:28, Christian Weinz wrote: > Maybe I didn't include the VGA option in the make menuconfig process. > How can I solve this problem? You need to add the VGA Option ROM (VGA BIOS -> Add VGA BIOS image). I've extracted it from the UEFI, but you also could use these: http://www.coreboot.org/index.php?title=ASRock_E350M1&oldid=11114 at the end of the page or you also may be able to use the default AMD fam14 (Persimmon) vbios. You will need to agree to the click through: http://wwwd.amd.com/support/vbioslic.nsf/userverify?openform http://www.coreboot.org/AMD_DB-FT1_PERSIMMON It's a pity, that bios_extract didn't work for now. You could use the AMI Aptio EFI MMTool with wine: http://win-lite.de/benutzer/fernando/BIOS-Tools/AMI_Aptio_EFI_MMTool_v4.50.… You need to extract OntarioEFIVbios with PCI ID 1002,9802 as Option ROM.

ASUS KCMA-D8 workstation board port offer
by Timothy Pearson 20 Jan '17

20 Jan '17

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 All, After reviewing some of the comments on the ASUS KGPE-D16 being essentially too large of a system and too expensive for many people, and the fact that modern, blob-free systems are not really available in the mid-range arena, Raptor Engineering would like to offer to create a native initalization blob-free port for the ASUS KCMA-D8, which is essentially the KGPE-D16's ATX-compatible "little brother". We would be asking $15,000 for the port, including upstreaming to the master coreboot tree. We already have extensive experience with these Family 10h/15h boards, and would be able to create a port of similar quality to the existing KGPE-D16 source in terms of both code quality and overall functionality. If this is something you might be interested in please let me know. We are able to accept multiple payments from various sources for the same project (within limits), so if this is something your local Linux groups or similar might be interested in we should be able to keep the cost on any one individual or organization to a reasonable level.

Re: [coreboot] F2A-85M: Different VGA BIOS needed after CPU Upgrade?

Hi John, > It sounds to me as though the PCI id's of the graphics card for the > upgraded CPU may be different (I could be totally wrong about that, so I > defer to others on the list if I'm barking up the wrong tree) and your > coreboot image may need to be updated accordingly. Of course, it could > also be the video BIOS that's the problem as you've suggested. Thank you for the hint. I inspected that, but the PCI-IDs actually look the same: 00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Trinity [Radeon HD 7480D] [1002:9993] (A4-5300) and 00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8670D] (prog-if 00 [VGA controller]) (A10-6700) Looks like the VGA BIOS is really different: # diff vgabios_a4-5300.bin vgabios_a10_6700.bin Binary files vgabios_a4-5300.bin and vgabios_a10_6700.bin differ Guess I will have to to "update" the VGA BIOS then.

The board had Coreboot installed before with the VGA BIOS extracted from the A4-5300. However, I did not get any video output when trying to boot after the upgrade, so I replaced the flash chip with a backup with the vendor BIOS that works. > > > > Is it likely that the A10-6700 needs a different VGA BIOS or does this this rather look like a different issue?

Linux 4.7 kernel payload with CoreBoot 4.4
by Trammell Hudson 12 Dec '16

12 Dec '16

The Linux 4.7 kernel payload crashes early in the boot process with CoreBoot 4.4. I traced it to these instructions that are finding a safe spot to decompress the rest of the kernel and patched around it with a hard coded location: diff -u --recursive /home/hudson/build/clean/linux-4.7/arch/x86/boot/compressed/head_64.S ./linux-4.7/arch/x86/boot/compressed/head_64.S --- /home/hudson/build/clean/linux-4.7/arch/x86/boot/compressed/head_64.S 2016-07-24 15:23:50.000000000 -0400 +++ ./linux-4.7/arch/x86/boot/compressed/head_64.S 2016-08-05 12:07:11.399854225 -0400 @@ -340,9 +357,15 @@ 1: /* Target address to relocate to for decompression */ +#if 0 movl BP_init_size(%rsi), %ebx subl $_end, %ebx addq %rbp, %rbx +#else + // coreboot does not populate the init_size boot param? + // fake it with a hard coded value + movl $0x97b000, %ebx +#endif /* Set up the stack */ leaq boot_stack_end(%rbx), %rsp It seems that the Linux kernel bzImage is supposed to set this value, rather than coreboot, so my comment is likely incorrect. Dumping linux-4.7/arch/x86/boot/header.o, it looks like init_siez is supposed to be 0xcf5000, so I wonder if %rsi is pointing to the wrong location. In 4.6.4 the computed address was hardcoded: movl $LOAD_PHYSICAL_ADDR, %ebx /* Target address to relocate to for decompression */ addl $z_extract_offset, %ebx 3e: bb 00 00 00 01 mov $0x1000000,%ebx 43: 81 c3 00 00 00 00 add $0x0,%ebx -- Trammell

Hi, FOSDEM 2017 deadlines are soon. Do we want to have a full developer room, a talk or just a stand? Unfortunately I won't be able to attend, so someone else will have to be the formal contact for organizing our stand/devroom/talk. I will help with submitting proposals if this is desired by the person organizing our stand/devroom/... Who is willing to take care of our FOSDEM 2017 presence? https://fosdem.org/2017/news/2016-07-20-call-for-participation/ Deadlines: Developer Rooms: 9 September Main Track Talks: 10 October Stands: 31 October Lightning talks: 25 November Regards, Carl-Daniel

Building Intel SoC Apollo Lake with DDR3L+PMIC
by morris.wang 11 Oct '16

11 Oct '16

Hello, I am building coreboot image for Apollo Lake. My designed mainboard comes with DDR3L SODIMMs + PMIC. To my knowledge, RVP1 board is for DDR3L SODIMMs and discrete VRs. RVP2 board is for LPDDR3 and PMIC. If I selected under coreboot configuration: Mainboard --> Mainboard vendor (Intel) Mainboard model (Apollolake DDR3 RVP1) How to modify VR type from Discrete to PMIC??? Kind regards, Morris

i2c_writeb vs i2c_raw_write output
by Haleigh Novak 07 Oct '16

07 Oct '16

Hello All, I am currently trying to send POST codes from Coreboot (downloaded approximately a month ago) to a Beagle I2C/SPI reader, specifically via i2c. I don't know the register needed for i2c_writeb() so I figured I would use i2c_raw_write(). In general since I have been unable to locate anything explaining the difference between the two functions I would really appriciate it if someone could explain it or direct me to where I can find documentation. I am hoping that the explaination/resource will either tell me where / or direct me to how I can figure out where the i2c_raw_write will write to (if it will just write directly to the Beagle or somewhere else)? Or would it be better to send it to a register with i2c_writeb()? I am running Coreboot on an ASROCK Mainboard, model IMB-A180. Thank you. HN

LPC and m.2 connector
by Rafael Machado 30 Sep '16

30 Sep '16

Hi everyone I have a question. Sometime ago i bought a Mini Pcie post card to do some tests, and it works really well, on a really old notebook. Now I'm doing some research on a newer notebook, that doesn't have a Mini Pcie connector. The only available connector is a m.2 Key A. So my question is. What are the chances os my PCie post card work on the m.2 connector after having an adapter like these: [image: pasted1] [image: pasted2] Does any one know if the m.2 connector has any direct connection to the LPC lines, on the same way as the PCIe slots have ? Thanks and Regards Rafael R. Machado
