A few weeks ago I externally flashed my T440p using version 1.0.6.

Today, after rebooting with iomem=relaxed, I tried to update internally to 1.0.7 with sudo ./skulls.sh -b t440p, but I got the following error:

Error: Image size (12582912 B) doesn't match the flash chip's size (8388608 B)!

I am not sure if I did something wrong during the initial flash and I am not familiar with this error, but below are the full outputs of my flashing commands:

I can't reproduce this. This is very strange. not sure whether Linux v6.1 does something differently in this case now - I'm still using v5.10 based kernels. Let's leave this issue open to check that.

Ok so I installed Debian which uses Linux v5.10 and I was able to update internally to 1.0.7, so I think Linux v6.1 does something differently.

One thing to note: I had no problem updating my X230 internally to 1.0.7 from 1.0.6 while using Linux v6.1, so this issue at least does not affect the X230.

interesting - looks like that'll be haswell-specific. we'll see. thanks for reporting.

Hi! I have both x230 and t440p and had the same issue only in t440p (Archlinux kernel 6.1.15-lts) which I was able to fix following flashrom FAQ.

That is as root:

modprobe -r lpc_ich

Or oneline with update:

modprobe -r lpc_ich; sleep 4; ./skulls.sh -b t440p

No need to enable iomem=relaxed in grub parameters.

Hope it helps
