Hey there, flashrom told me to send you this log alongside the output of lspci, so here you go ;) Kind regards, A. Engelke ======================================================================== $ sudo flashrom -p internal -r curie-backup.rom flashrom v1.2 on Linux 5.6.14-20.05.23.amdgpu (x86_64) flashrom is free software, get the source code at https://flashrom.org Using clock_gettime for delay loops (clk_id: 1, resolution: 1ns).

We could not detect this for sure because your vendor has not set up the SMBIOS tables correctly. Some internal buses have been disabled for safety reasons. You can enforce using all buses by adding -p internal:laptop=this_is_not_a_laptop to the command line, but please read the following warning if you are not sure. Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See the manpage and https://flashrom.org/Laptops for details. If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff.

Note: flashrom can never write if the flash chip isn't found automatically.

Converting STLinkV3-MODS to a high speed QSPI programmer
by Miklos Marton 24 Jul '20

24 Jul '20

Hello folks, Now that the STlinkV3 bootloader protocol had been broken unlocked I started to wondering about creating an alternative firmware to it which would allow very high speed SPI programming (up to 108 MHz clock) even with quad SPI configuration. Other than the firmware it would require the creation of an interposer PCB with proper signal integrity but I think I can manage that. AFAIK at the moment there are not any QSPI flashrom programmers, so some flashrom side patching will needs to be done. I would be courios if anyone else would be interested in such a project! -- Best regards, Miklos Marton
