This one is super interesting -- it's triggering an error in the parser. I'll look more at this tomorrow -- thanks!

[hughsie]

Okay, weird -- the file is smaller than I expected:

du -h ../../fwupd-test-roms/lenovo-thinkbook_14s_yoga_itl-lenovo_mt_20we_bu_idea_fm_thinkbook_14s_yoga_itl.bin
8.1M

i.e. it's truncated at 0x800000 -- and included me, desc and not bios -- but we should have created a blob with image_size=0x17fffff -- i.e. there seems to be something funky with the dump script.

[hughsie]

@a-andre I've modified the script to be more paranoid -- can you try again (and re-paste the script console output) with https://raw.githubusercontent.com/fwupd/fwupd/wip/hughsie/ifd-helper/contrib/dump-mtd-ifd.py please. Thanks!

I forgot to mention, this was created using Arch Linux.

tried to read 0xffffff and instead got 0x0

Do you have any new lines in dmesg about intel-spi please?

No. There is no new line in dmesg after running the script.

[hughsie]

I've asked Mauro (the intel-spi MTD expert) to look at this as I'm a bit stumped.

[hughsie]

@a-andre can you get us the output of mtdinfo -a please
