Re: [coreboot] T450S + Coreboot
by Mike Banon 28 Aug '18

And even if there weren't any problem with Intel Boot Guard, its not that easy to add a support for new board (impossible to do it over weekends, especially for the newcomers). If I were you I would have sold these T450S and bought some machine already supported by coreboot. It could be one of those Intel Thinkpads (although you'll have to spend time cleaning Intel ME) or maybe Lenovo G505S quadcore AMD laptop which doesn't have any Intel ME / AMD PSP backdoors in its' CPU at all - so no need to clean anything.

Re: [coreboot] USB cannot work

GRUB has an `lsmod` command, if that lists something with ehci or xhci, that might give a clue. Actually, I would just grep the source code. In my current GRUB master checkout, `git grep -i xhci` returns nothing. > But another question is then why EHCI driver cannot work when > running with Coreboot on Denverton-NS platform?

Sorry but T450S is not supported by coreboot. Here is a list of laptops that ARE supported: https://www.coreboot.org/Supported_Motherboards/old On Mon, Aug 27, 2018 at 4:23 AM Brian Herman <bherman.aconspart(a)gmail.com> wrote: > > I am in contact with a person with the means to reprogram a T450S. > https://www.allservice.ro/forum/viewtopic.php?t=1311 > What would I have to do to make coreboot work? > I think I would have to have two laptops or at least motherboards right? > -- > coreboot mailing list: coreboot(a)coreboot.org > https://mail.coreboot.org/mailman/listinfo/coreboot

Extracting MRC training data
by Antony AbeePrakash X V 27 Aug '18

27 Aug '18

Hi All, We are developing coreboot for Apollo lake custom board. MRC training data is enabled in FSP using Binary configuration tool. We are facing the following observations: 1. After flashing the first boot takes 10 sec to boot. 2. For next cold boot the boot time takes 6 sec and remains same. So we dumped the flashed coreboot image and re-flashed the dumped coreboot image to the chip. 1. After flash the first boot takes 6 sec to boot. 2. For next cold boot also the same 6 sec is observed. Could you please explain on the above observations ? Can we extract the MRC training data and add it to the coreboot image ? If yes, could you please share the steps to be done ?

Re: [coreboot] T450S + Coreboot

hi, at the current state it is not possible to properly install Coreboot to a ThinkPad, that is newer than the **3* series, because since Haswell, Intel introduced a new technology called "Intel Boot Guard"- which prevents any firmware that is not signed by Intel firmware to be used by the device. Therefore, no effort went into these devices yet, and probably never will, until there is a way to disable it permanently. Best regards Sellerie/Christoph Pomaska Am 27.

Pointless IMO. I doubt those guys have the skill to do so but for those who do - you'd spend tens of thousands in order to have a port for an old machine that still is stuck with ME and hardware init done entirely by binary blobs. I would save your money and instead buy an ivy/sandybridge thinkpad (can nerf the ME - but not disable which is impossible) or a G505S (owner controlled, no ME/PSP) and maybe also buy a KCMA-D8 (libre firmware, no ME/PSP thus owner controlled and can play the latest games at max settings in a VM with a good AMD graphics card) or TALOS 2 (open source firmware, it is a brand new high performance OpenPOWER system, it is a true special rarity) etc.

T450S + Coreboot
by Brian Herman 27 Aug '18

I am in contact with a person with the means to reprogram a T450S. https://www.allservice.ro/forum/viewtopic.php?t=1311 What would I have to do to make coreboot work? I think I would have to have two laptops or at least motherboards right?

bayou payload
by ron minnich 26 Aug '18

26 Aug '18

if I set bayou as the payload, i.e I get CONFIG_PAYLOAD_BAYOU=y in the file, nothing ever gets built. This is not as a secondary payload, just the payload. I believe this worked at one time. Am I missing something? thanks ron
