Lac, you probably installed flashrom from a binary package. The fix Edward gives is intended to go into a source file sb600spi.c and then compiled to produce the executable binary on your Lenovo Ideapad 3. Go to: https://www.flashrom.org/Downloads You will need to make sure you install the required dependent apps & libraries, then download the source. My suggestion is from GitHub thus: # git clone https://github.com/flashrom/flashrom.git When you have the source downloaded, navigate to the flashrom directory you have made and edit sb600spi.c to include your rev=0x51 chip. It's just a one line edit. Then, while in the flashrom directory, do # make stuff happens # make install Then try running: # flashrom -p internal Hope this helps, Clay On Mon, Dec 21, 2020 at 1:29 AM Lac Onis <laconis71@gmail.com> wrote:

Then, while in the flashrom directory, do
git fetch "https://review.coreboot.org/flashrom" refs/changes/79/48779/1 && git cherry-pick FETCH_HEAD then proceed with the rest of Clay's instructions..
# make stuff happens # make install
Then try running: # flashrom -p internal
Hope this helps, Clay

Lac, Edward has fixed flashrom to accommodate your 0x51 spi, so no need to apply any patch. You can use either: *git clone https://review.coreboot.org/flashrom.git <https://review.coreboot.org/flashrom.git> * or *git clone https://github.com/flashrom/flashrom.git <https://github.com/flashrom/flashrom.git>* then navigate to the resulting flashrom directory, and do: *make* *make install* Then run flashrom: *flashrom -p internal* It should show your spi chip. Best Regards, Clay BTW, my interest is because I have a similar AMD Zen Promontory chip (0x61) as your 0x51 chip. Welcome to the club!
