Acer Aspire 8730g (Nuvaton/Winstron WPCE755)
by celliwig＠nym.hush.com 02 Jun '23

02 Jun '23

Hi, This may be of help to someone (or not ;)! Following the request in the 'Laptops' section of the wiki to send in code, here's my attempt to implement an opaque programmer for the WPCE775. Obviously programmer_table.c/programmer.h need to be updated to reference the programmer, and the Makefile updated to actually build it. i8042 code is there to reset the KBC as the trackpad will go crazy after swapping the EC to Flash Update mode. This is very much a work in progress. It's only been used to write/erase a single sector so far. So use at YOUR OWN RISK!!! Some notes on extracting this from a phlash16 WPH file can be found here: https://github.com/Celliwig/Reverse-Engineering/tree/main/Acer/8730g Specifically the found WPCE775 commands: https://github.com/Celliwig/Reverse-Engineering/blob/main/Acer/8730g/wp-acc… Hope this helps somebody, Celliwig

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 flashrom 1.4.0-devel (git:) on Linux 5.10.0-21-amd64 (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). Found Spansion flash chip "S25FL128L" (16384 kB, SPI) on ch341a_spi. === 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 version of flashrom. If you are running the latest development version, please email a report to flashrom(a)flashrom.org if any of the above operations work correctly for you with this flash chip.

# 25th May 2023, 6.00-7.00am UTC+0 Attendees: Stefan, Damien, Edward, Anastasia ## Decision summary * see notes ## Agenda * [aklm] What's left to branch 1.4 * ready to delete makefile? * only one windows programmer left, to build with meson * progress bar * feature is incomplete, we can add [experimental] to the manpage TODO * amd spi [https://review.coreboot.org/c/flashrom/+/65237](https://review.coreboot.org… * renaming chain from Martin goes first * Edward's chain goes after that * new erase stuff can be better tested * let's split ichspi into two * [aklm] What is our procedure to sign the release tarballs? The process for 1.3 was rather chaotic, better have a well-defined process. * aklm needs to create the key * next meeting we sign * [aklm] let's enable erase/write optimisations by default? DONE * I want to complete this test [https://review.coreboot.org/c/flashrom/+/67535](https://review.coreboot.org… * static bool use_legacy_erase_path = false breaks one unit test full_chip_erase_with_wp_dummyflasher_test_success -> FIXED * [heijligen] add Chromebook specific documentation * aklm: maybe we can collect the links to chromebook documentation pages which are publicly visible. It would be good to have a page on the website which is a collection of documentation specific to chromebooks. TODO aklm try to find out. * existing docs might be removed and re-written, so adding links won't work * we need to start a new page, and gradually add stuff * check what are the questions on the mailing list, the most common questions need to be documented first -- Anastasia.

by lame_temp_email 21 May '23

21 May '23

exact same error readout as Daniel Rozsnyó (see link below, from April 23): https://mail.coreboot.org/hyperkitty/list/flashrom@flashrom.org/thread/P7TQ… Could not find in documentation any indication of non/compatibility of mainboard, computer, or CPU. Would appreciate any help to confirm or deny if possible to make headway towards successful flashing. Thanks. Sent with [Proton Mail](https://proton.me/) secure email.

flashrom discord channel
by Anastasia Klimchuk 20 May '23

20 May '23

Hello everyone, I wanted to share that there is a #flashrom channel on discord. It existed for a while, but I only very recently learned about it. I suspect it might be the same for many people who have no idea the channel exists. I updated the Contacts page (old and new) with the info: see https://www.flashrom.org/Contact#Discord or check the latest doc/contact.rst in your repo, and follow the invite link. The channel is on the coreboot server, so if you join you get all of coreboot and flashrom channels in one place, which is convenient. See you there, -- Anastasia.

MX25U12873F Flash ROM Write Success
by 抗グリアジン IgG抗体 20 May '23

20 May '23

My name is gliadin. I used Flashrom to write using RayeR's RayeR_SPI. here is report. Since the circuit is a breadboard and a voltage divider with resistors, there may have been a lot of errors. However, I am satisfied because the parallel port could actually become a ROM writer. thank you. I connected the load "MX25U12873F" to a 60Ω resistor and a 200Ω voltage dividing circuit, and adjusted the voltage to around 2.0v. Others were made by connecting 4 resistors of around 2kΩ, Darlington transistor (2SC1959) power through a 1.2kΩ resistor, and connecting to GND. The four resistors are on the JSPI side (ROM side). Otherwise the ROM could not be searched. When I made a dump file of the written contents and checked the binary data with GHex, it was written firmly to the end, so I don't think there is a problem, but I will report it. sudo flashrom --programmer rayer_spi -w B350M_E7A37AMS.1O6 flashrom v1.2 on Linux 5.15.0-72-generic (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). Using RayeR SPIPGM pinout. Found Macronix flash chip "MX25U12835F" (16384 kB, SPI) on rayer_spi. Reading old flash chip contents... done. Erasing and writing flash chip... Erase/write done. Verifying flash... FAILED at 0x001cd9cf! Expected=0x46, Found=0x0d, failed byte count from 0x00000000-0x00ffffff: 0x1804b4 Your flash chip is in an unknown state. Please report this on IRC at chat.freenode.net (channel #flashrom) or mail flashrom(a)flashrom.org, thanks!

GallopMem 25Q64ASIG
by Chris Kuethe 16 May '23

16 May '23

Hi Folks, I was able to dump an 8MB GallopMem device using flashrom. As this does not appear to be a natively supported device. Here's the output from "flashrom -VV -p ch341a_spi" -- GDB has a 'break' feature; why doesn't it have 'fix' too?
