Hi Werner, The SeaBIOS .config is always been reset when I recompile the coreboot. I am trying to figure out how to avoid that.
Hi Zoran, I did not get grub2 prompt shell so I cannot do anything. I don't use UEFI or Legacy. I just use grub2 as coreboot's payload and if there is a shell prompt, then I can bring my linux kernel up. -Hilbert -----Original Message----- From: Zeh, Werner [mailto:werner....@siemens.com] Sent: Wednesday, January 10, 2018 1:34 PM To: Hilbert Tu(杜睿哲_Pegatron); coreboot@coreboot.org Cc: David Hendricks; Leo5 Huang(黃儀祥_Pegatron); Zoran Stojsavljevic Subject: AW: [coreboot] BDX-DE PCI init fail Hi Hilbert. It might be nothing but if I have a look at your last attached log I can't see SeaBIOS finding any USB devices. There is just one Error mentioned: >ehci_wait_td error - status=80e42 So what is special with SeaBIOS and Broadwell-DE: you have to unset the config switch called "CONFIG_MALLOC_UPPERMEMORY" in SeaBIOS config. With this option set SeaBIOS has issues with USB on Broadwell-DE. It might help you, just check it and give it a try if not unset already.
