Do you mean supported boards table, and the 3rd column from left for ALIX 2C or ALIX 6 has invalid links? That would not be your fault. When alix.2d was pushed to board_status, it also refreshes .2c and .6 entries even when they don't exist as individual updates on the wiki. Kyösti

SPI Flash debug console on H8SCM
by Fabian 21 Sep '17

21 Sep '17

Hi everyone, I try to get coreboot run on my H8SCM. Sadly I get no log over serial or USB. So I want to give SPI console a try. It seems to be a very new feature introduced here [1]. When I compile coreboot it fails with this warning: warning: (CPU_SPECIFIC_OPTIONS && CPU_SPECIFIC_OPTIONS && CPU_SPECIFIC_OPTIONS && CPU_SPECIFIC_OPTIONS && CONSOLE_SPI_FLASH) selects BOOT_DEVICE_SPI_FLASH_RW_NOMMAP_EARLY which has unmet direct dependencies (SPI_FLASH && BOOT_DEVICE_SPI_FLASH_RW_NOMMAP) As written in [1] it's only tested for Skylake. How much effort is necessary to port it to my board? Are there more Information about SPI console? Or is there an other way to get log from my board? One more question to the AMD experts: There are two motherboard models "H8SCM" and "H8SCM (Fam10)". Whats the difference? Greetings, Fabian [1] https://mail.coreboot.org/pipermail/coreboot/2017-June/084538.html

I'm not sure if it helps, but we can commit to test all PC Engines platform. 3 weeks ago we obtained all ALIX platforms. Unfortunately things like ALIX.1C are no longer in production (replaced by ALIX.1E). Development recovery for platforms not touched for 3 years takes time. We are confused about various pieces when trying to upload recent board status: 1. How to handle situation when hardware was replaced by new revision ? 2. Is cbmem required ? (Geode LX do not have support for cpufreq - cbmem complains) 3. There is seem to be some glitches in the system - not sure if triggered by us eg. alix.6 bootlog link seems to be broken. We feel responsible for PC Engines platforms and keeping them in coreboot tree. Things that I think we can do better is: 1. Adding missing wiki pages for PC Engines platforms. 2. Adding people from 3mdeb as official maintainers of PC Engines platforms - would that be accepted ?

Is there FSP binary used for this platform ? Both with Tirumalesh we asked Intel, but they point to documentation that I have no access to.

doubts on FSP

I try to understand coreboot source for x86 (intel/kblrvp). But I have encountered some difficulties. In romstage fsp_memory_init, try to find fspm.bin. ``` if (cbfs_boot_locate(&file_desc, name, NULL)) { printk(BIOS_CRIT, "Could not locate %s in CBFS\n", name); die("FSPM not available!\n"); } ``` But my firmware not contain. ``` ➜ coreboot git:(master) build/cbfstool build/coreboot.rom print Name Offset Type Size cbfs master header 0x0 cbfs header 32 fallback/romstage 0x80 stage 36876 cpu_microcode_blob.bin 0x9100 microcode 0 fallback/ramstage 0x9180 stage 75335 vgaroms/seavgabios.bin 0x1b800 raw 27648 config 0x22480 raw 107 revision 0x22540 raw 570 spd.bin 0x227c0 spd 2048 cmos_layout.bin 0x23000 cmos_layout 1132 fallback/postcar 0x234c0 stage 24932 fallback/dsdt.aml 0x29680 raw 16738 fallback/payload 0x2d840 payload 63916 payload_config 0x3d240 raw 1652 payload_revision 0x3d900 raw 234 (empty) 0x3da40 null 1713240 mrc.cache 0x1dfec0 mrc_cache 65536 (empty) 0x1eff00 null 16280 bootblock 0x1f3ec0 bootblock 49152 ➜ coreboot git:(master) build/cbfstool build/coreboot.rom layout -w This image contains the following sections that can be accessed with this tool: 'BIOS' (read-only, size 2097152) 'FMAP' (read-only, size 256) 'COREBOOT' (CBFS, size 2096896) It is at least possible to perform the read action on every section listed above. ``` ------------------ 王翔安全研究员广州市腾御安信息科技有限公司广州市天河区珠江新城华穗路406号保利克洛维二期中景A座1020-1024
