Fwd: Dell 3100 Chromebook

---------- Forwarded message --------- From: Tim Tech <agitimtim(a)gmail.com> Date: Thu, May 20, 2021 at 12:07 PM Subject: Re: [flashrom] Dell 3100 Chromebook To: Mike Banon <mikebdp2(a)gmail.com> The flashing setup seems to work fine with any other chip. The chip in question is a Winbond 25Q128FWPF. This chip is on the Dell 3100 and HP 11 G6 EE chromebooks and is the only chip we've had an issue with so far. I attached an image of the chip itself, in case there is any other info on there you need. I don't see this chip on the supported hardware, so maybe it is not yet supported?

Are you able to help with the following issue? Thank you *Calibrating delay loop... OK.Found Winbond flash chip "unknown Winbond (ex Nexcom) SPI chip" (0 kB, SPI) on ch341a_spi.* *This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITEThe test status of this chip may have been updated in the latest developmentversion of flashrom. If you are running the latest development version,please email a report to flashrom(a)flashrom.org <flashrom(a)flashrom.org> if any of the above operationswork correctly for you with this flash chip. Please include the flashrom logfile for all operations you tested (see the man page for details), and mentionwhich mainboard or programmer you tested in the subject line.Thanks for your help!Read is not working on this chip. Aborting.*

Found unknown SPI flash chip
by Kratzmann, Jakob 11 May '21

11 May '21

Hello flashrom team, I have detected an unknown SPI flash chip. The output of the command `flashrom -VV -p linux_spi:dev=/dev/spidev0.0,spispeed=512` can be found in the attachment. I am using a Raspberry Pi 2 B+ with flashrom on Linux 5.10.17-v7+ (armv7l). XMC 0H128AHIG P1W93800 is written on the SPI chip. Please do not hesitate to contact me if you have any further questions. Best regards Jakob Kratzmann

Re-building after failed flash
by Clay Daniels 07 Apr '21

07 Apr '21

I should have been more patient, but I used flashrom to attempt to install a bios update from MSI, and it kept looping through the attempt giving an error message about "unable to erase". I eventually got the pid # with top, and killed the job. Everything seemed OK, so it was late and I shut the computer down with the normal Ubuntu shutdown. The next day, it would not boot. By not boot, the fan & lights came on, I thought I heard hard drives, but absolutely no video. I messed with it for several days, then ordered a new motherboard. After installing the new mb, hopefully correctly, I have the same problem. I can't think of anything left undone. Is it possible a failed flash can fry the video card? I re-used memory, etc, but the monitor shows no activity. When I built this computer in September 2019, the motherboard worked out of the box, and already had a bios installed. I am assuming the new motherboard has a bios installed too. Any help appreciated, Clay Daniels

Re: (Re)Unsuccessful Read with FlashRom
by Mike Banon 07 Apr '21

If you suspect that your BIOS is infected (BadBIOS?), I could only suggest doing a hardware ISP flashing with one of the flashrom-supported programmers (i.e. green PCB ch341a) and a test clip like SOIC8 (to be able to attach to a chip without any soldering) while the board is turned off of course. This should be the most reliable. Before flashing a new known good BIOS image that you might obtain i.e. by extracting from a manufacturer's update utility, please dump the previous contents with a programmer: so that you'll be able to recover from it just in case, and maybe even look through it for any hard evidence of a BIOS virus to share it with the community (if that's really true, could be quite interesting for research purposes). Also I copy this message to a flashrom mailing list, in case someone else could also advise you. On Wed, Apr 7, 2021 at 2:05 PM Rahngue NGARIERA <youetonam(a)gmail.com> wrote: >> >> Hi Mike. I didn't mention it in my previous email, but I used also flashrom 0.9.6 on Ubuntu 14.4 Which failed on both Probe and Read with "Hardware sequencing was requested but the flash descriptor is not valid.

And checking on the main board I did see that chip. It's AT26DF081A. I did try to read on FlashRom 0.9.4 (on DOS) using the -c parameter with AT26DF081A first (as in -c AT26DF081A) but that failed. Then just to see, I tried to read with -c AT25DF081A ( since 0.9.4 was seeing two chips). But it also failed.
