Flash special target
by Michael Matz 25 Jan '14

25 Jan '14

Dear team, may you can help me for to fix some problem. I'm working in a company and we repair and produce for a well known costumer. Normally we upload the test firmware (Linux) to the device by Ethernet, with an encrypted Windows machine controlled from the customer. The tester show only not useful error, like DUT load stub. I work in the department for recover and repair ( Customer return ). Unfortunately the company is not willing to pay for professional tools. So may colleges (asian) they scrap the units, but my boss (Asian) complain. Now too the situation, I have a few units with firmware (Linux) and fortunately the have had a problem with the Ethernet so the tester is not able to delete the flash. I can use it for to debug the unit with the Bus pirate at UART mode. So I want to read this flash rom's and reprogramme the others to debug them. It is not clear the MCU is complete working or not, may some pins have a micro crack. How ever I have no SPI port on it, I have an JTAG an a Serial port. The flash it is a 1 to 4 MB TQFP with 48 pin. Exchanging the chip was already working for me, but as you know it is difficult and dangerous to solder on a 6 layer PCB. Of course I have all information about the chips, schematic and layout. I believe, I can use the serial port with bit-bang. But I have had no success (I read it one time on a other schematic). I'm the only one in the company use and have experience with Linux. So, if you have some time and willing to help, it will be great. As pay back I can give you the information with what parallel flash it is working (ICP). The only things, are not allowed for me is: to tell the customer name, share schematics, his product or firmware or CPU they use. But I can say it is a MIPS based MCU. Thank you in advance for any answer or help you can give to me. Sincerely Mike

MX25L25635F support?
by Brian Rak 24 Jan '14

24 Jan '14

How would I go about getting an additional chip supported? I've got one of these: http://datasheet.octopart.com/MX25L25635FZNI-12G-Macronix-datasheet-1253711… connected to a buspirate. I'm able to detect it: Found Macronix flash chip "unknown Macronix SPI chip" (0 kB, SPI). but that's about it. This isn't part of a BIOS (it's actually used by an IPMI controller), so I don't have any ability to attempt to use an internal programmer.

Fwd: Intel (R) Developer Zone - Case #: 00091086 [ ref:_00DU0JBUY._500U0AExiQ:ref ]
by Elmar Stellnberger 23 Jan '14

Dear FlashRom mailing list, I have a pb dot se 2 netbook with a CG82NM10 Bios chip. The good news is that Intel was ready to give us all necessary tech docs for supporting it by flashrom. Not so good news are: - the chip is not removable so trying to write it would likely only work once - I currently don`t have time to join your programming effort Nonetheless I believe that we should at least try to offer read support for the given chip. Being able to verify the installed Bios can already be of great value when it comes to system security. If that has worked well I am also ready to venture testing a write support though I would have to ask whether and how the chip could be repaired on a failed write attempt.

Supermicro X9SCL+-F BIOS (via buspirate)
by Brian Rak 22 Jan '14

22 Jan '14

The Supermicro X9SCL+-F has an SPI programming header which lets you access the BIOS without soldering. The pinout looks something like this: (orient board so PCI slots are on the top) DI - | | - GND CS * * VCC CLK - | BIOS | - WP DO * * HOLD HOLD - | CHIP | - DO WP * * CLK VCC - | *| - CS GND * * DI (edge of board) There is also a SPI jumper (J29). I'm unsure of what this does, but I had it open while doing this (though, it seemed to work closed as well) Once connected properly, the BIOS is detected: Found Winbond flash chip "W25Q64.V" (8192 kB, SPI) on buspirate_spi. I'm assuming everything else will work, though I'm still waiting for the initial read to complete.

Re: [flashrom] F2A85-M with flashrom

Hi, Thank you for the informations. I just tested with succes flashrom on the versions 6002, 6004, 6102, 6402. Only the 6404 version does not work with flashrom and it is the only version that has the printable character sequence "SecureBootSetup"... I still have a few things to do with coreboot. Thank you very much.

I ran into this too, and found out that F2A85M's BIOS v6404 prohibits access where v5018 (the version that was preloaded on my board) does not. I haven't tried whether any other build (5103 or 5104 or 51047 or 5202 or 6002 or 6004 or 6102 or 6402) blocks full access. To solve this problem: either downgrade or read the chip using (a breadboard and) an external programmer. > > Thanks, Best regards, > > Loic > http://hackurx.wordpress.com HTH, Idwer
