Change in flashrom[master]: dediprog: Fix SF600 4BA mode
by Patrick Rudolph (Code Review) Nov. 25, 2023

Nov. 25, 2023

Hello Patrick Rudolph, I'd like you to do a code review. Please visit https://review.coreboot.org/c/flashrom/+/34629 to review the following change. Change subject: dediprog: Fix SF600 4BA mode ...................................................................... dediprog: Fix SF600 4BA mode Flash chips greater than 16MiB require 4BA mode support. Current master doesn't support such mode as the SF600 uses PROTOCOL_V3. Fix protocol version check to support 4BA on PROTOCOL_V3, too. Tested on SF600 V:7.2.45 Able to read and write "IS25WP256" (32768 kB, SPI).

Change in ...flashrom[master]: [RFC] cli_classic: Add `--mode (read|write|verify|erase)` parameter
by Nico Huber (Code Review) May 13, 2021

May 13, 2021

Nico Huber has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/30979 Change subject: [RFC] cli_classic: Add `--mode (read|write|verify|erase)` parameter ...................................................................... [RFC] cli_classic: Add `--mode (read|write|verify|erase)` parameter In case the user only wants to specify files for specific layout regions, we need a way to set the operation without specifying a file. Instead of making the <filename> argument optional, we can add a new syntax for this particular purpose. This way, we avoid complex command line parsing and can do more sanity checks and provide better error messages. TODO: Update manpage in case this gets accepted.
