Re: Support for GD25LR512ME flash chip.

Victor, Thank you so much for the datasheets! I did a review of the pending patch, and now it will be possible to finally finish the patch from 2021 and get the chips submitted. Also thank you for attaching the log. Not sure if the log is complete? It ends at the start of the reading operation, but there is no final message of SUCCESS or FAIL. However, importantly, I could see in the beginning of the log which platform was detected, and it is Promontory. Which means... Avinash, Most likely you are hitting a known issue, you can read more details here: https://ticket.coreboot.org/issues/370 The issue is for Promontory, and also for chips larger than 16Mbyte: which is exactly what you have. I was actually trying to get help from AMD with this issue, so it's really good to have you here on the mailing list! Maybe you can help? Someone from AMD would be in the best position to fix Promontory, you have all the datasheets available, and all the hardware. Thank you!

Adding support for a new chip
by Jean-Baptiste Skutnik 07 Jun '24

07 Jun '24

Hello all, I broke my motherboard and flashrom would help me save 300$. I need to flash the BIOS chip and unfortunately, only the older version of the chip seems to be supported, so I would need to patch support in. The chip is the Winbond W25X40CL, which appears to be an upgrade over the W25X40 that flashrom supports. However, when hooking it up, the latter is detected and only the first 500K are available. I would need some guidance on what to do next. Looking through the gerrit I see the patches for new chip support add to flashchips.c and include/flashchips.h. Is there some documentation on what the fields represent in there so that I am not plugging randomly ? How does the process work when recognizing chips ? Would adding this chip create a conflict with its predecessor ? Thanks, JB

Issue with Flashrom: Failed Erase Operation
by Imed Hanchour 16 May '24

16 May '24

I am writing to report an issue I encountered while attempting to use Flashrom on my system. I am currently using Flashrom version 1.4.0-devel on a Raspberry Pi running Linux 5.15.61-v7+ (armv7l). When trying to perform an erase operation on a Macronix flash chip "MX25U3235E/F" (4096 kB, SPI) using the linux_spi interface, I encountered the following error: FAILED at 0x00000000! Expected=0xff, Found=0x00, failed byte count from 0x00000000-0x003fffff: 0x3b5631 ERASE FAILED! Erase/write done from 0 to 3fffff Erase FailedYour flash chip is in an unknown state. I have attempted to troubleshoot the issue by ensuring proper connections and trying the operation multiple times without success. I have also verified that the flash chip is supported by Flashrom. Could you please provide guidance on how to resolve this issue or any additional troubleshooting steps I can take? I am eager to contribute to resolving this problem and willing to provide any further information or logs that may be needed. Thank you for your attention to this matter. I appreciate your support and assistance. Best regards Imed

RFC: removing 1 second verification delay
by Brian Norris 12 May '24

12 May '24

Background: https://review.coreboot.org/c/flashrom/+/80807 A long time ago, in the pre-git times [1], flashrom added a 1 second delay to all verification, and claimed that some chips "need some time to calm down." The commit message claims it "fixes a few reports where verify directly after erase had unpleasant side effects like corrupting flash or at least getting incorrect verify results." It provides no details of what systems, chips, or programmers were involved. This delay remains in the --verify path today, and IMO, it's a big waste of time. If there are truly chips that are, say, deasserting the BUSY line before they're truly finished programming ... well, we should track those chips down and add targeted quirk flags for them. We shouldn't penalize all flashrom users in all cases for all time. Personally, I highly doubt that this delay is still relevant today -- there may have been a bug in some programmer that has since been fixed; there may have been some malfunctioning system that is no longer in use; ... or it's possible this is still hiding a real buggy chip somewhere out there. I propose: we still remove the delay. There's plenty of description in the above Gerrit link about why, and how we can handle regressions. (For one, it's relatively simple to split up a --verify operation into its constituent --write/sleep/--read operations, for debugging.) The request: 1. Tests: I've tested a few Chromebooks, but imagine this had to have been some more esoteric system. Extra testing is welcome. 2. Thoughts: does my proposal make sense? Am I missing something obvious? 3. Awareness: if nothing else, this email may serve to highlight in case we land the above patch and later hear back that there are some sketchy --verify reports from users. Thanks, Brian [1] The svn->git commit in question: commit 8ab49e72af8465d4527de2ec37b22cd44f7a1169 Date: Wed Aug 19 13:55:34 2009 +0000 Disallow erase/write for known bad chips so people won't try without a clear understanding

Thanks, Avinash, Can you advise which board are you using? I have tested this patch with the USB programmer only since I do not have access to the motherboard. Hi, Flashrom team, Can you also help on this?
