I've had success with READ, ERASE, WRITE with this part.
I'm unsure how to test PROBE and WP, but I am happy to do both if you send me some guidance as to what to do.
Thanks,
Bill

This flash part has status UNTESTED for operations: PROBE READ ERASE WRITE WP
The test status of this chip may have been updated in the latest development

please email a report to flashrom@flashrom.org if any of the above operations
work correctly for you with this flash chip. Please include the flashrom log
