partial_lock_test (Lock_top_quad, Lock_bottom_quad, Lock_bottom_half, and Lock_top_half) tries to: 1. Disable HWWP 2. Lock partial 3. Enable HWWP 4. Try to write the locked partial and expect a failure ... The 4th step only works on flashrom binary since the binary will set FLASHROM_FLAG_VERIFY_AFTER_WRITE=1 by default and it will error out while verifying. But libflashrom does not set any flag beforehand, so it has FLASHROM_FLAG_VERIFY_AFTER_WRITE=0 and thus it will think the write command works normally and raise no error. This causes the issue that flashrom_tester with libflashrom has been failed until today. To solve this issue, there are two solutions: 1. Take care of the default flags in libflashrom 2. Always pass --noverify to flashrom binary and verify it afterwards. To make both methods more consistent, I fix it with approach 1.

flashrom README
===============
flashrom is a utility for detecting, reading, writing, verifying and erasing
flash chips. It is often used to flash BIOS/EFI/coreboot/firmware images
in-system using a supported mainboard, but it also supports flashing of network
cards (NICs), SATA controller cards, and other external devices which can
program flash chips.
It supports a wide range of flash chips (most commonly found in SOIC8, DIP8,
SOIC16, WSON8, PLCC32, DIP32, TSOP32, and TSOP40 packages), which use various
protocols such as LPC, FWH, parallel flash, or SPI.
Do not use flashrom on laptops (yet)! The embedded controller (EC) present in
many laptops might interact badly with any attempts to communicate with the
flash chip and may brick your laptop.
Please make a backup of your flash chip before writing to it.
Please see the flashrom(8) manpage :doc:`classic_cli_manpage`.
