---------------------------------------- Bug #310: Coreboot 4.14 fails on a Lenvovo T440p https://ticket.coreboot.org/issues/310#change-1160
* Author: David Hoelscher * Status: Resolved * Priority: Normal * Assignee: Angel Pons * Start date: 2021-06-02 * Affected hardware: ThinkPad T440p * Affected OS: All (coreboot bug) ---------------------------------------- Hi all,
coreboot 4.14 dies on early boot. The T440p ended with led blinking and beep sound.
This was my first try - so i think it was maybe a problem with mrc.bin or vga.rom. But if I skip back to version 4.13, everything works fine (4.13 working config is appended). I don't know how to get debug information on this early stage of boot. Does anyone has a hint? A Raspberry Pi as an external flasher is available.
Further - is it possible to flash only the 4 MB BIOS chip? This IC is very easy accessible. I am afraid to disassemble the complete backplate to access the other 8MB chip again. Initially I flashed the complete Rom without ME on both chips.
