EC will not interfere if the board will be powered off, and you could directly flash a SPI chip without desoldering by attaching a test clip to it (which is connected to a flashrom-supported programmer like a cheap CH341A). Examples of the instruction: https://www.flashrom.org/ISP , http://dangerousprototypes.com/docs/Flashing_a_BIOS_chip_with_Bus_Pirate (for CH341A its the same, just a connection scheme and flashrom commands are a little bit different) On Fri, May 25, 2018 at 9:06 AM, Curi0 <[email protected]> wrote: > Hi, > I have a laptop with ITE 8518 and I want to try to port coreboot.
