Checked Pm25LV010 Chip for PEWR
by Matthias Larisch 19 Dec '13

19 Dec '13

Dear all, I successfully flashed a notebooks GPU BIOS SPI Flash Pm25LV010 using flashrom. I don't know why but I used Flashrom 0.9.4 and not the latest one and therefore had to add the WREN feature flag that is already present in 0.9.7. I used the bus pirate with 120kHz SPI mode. Notebook is fine again and a friend of mine happy :) (He flashed some non-mobile gpu bios from within windows using another tool... Don't ask) Regards, Matthias

I'm curious if it's just that SRP0 bit that seems stuck. If the /WP pin is not grounded, then hardware write-protection should not be in effect and you should be able to effectively disable write-protection by clearing the range of protected blocks even if SRP0 is set to 1. > > If you have a voltmeter handy, you can also try measuring the voltage >> on > > > the /WP pin (pin 3).

Trouble disabling write-protection on Chromebook
by BM-2cWKH3wgq8zXX9eHfba16oTc8b61ead4Yq＠bitmessage.ch 16 Dec '13

16 Dec '13

Hello flashrom developers, I'm having trouble disabling write-protection on my Samsung Arm Chromebook. So far I've removed the metallic sticker covering the "write-protect screw hole" according to the pictures on the Chromium wiki <http://www.chromium.org/chromium-os/developer-information-for-chrome-os-dev…>. On the Snow board, this hole ships with no screw in it. As root in developer mode, the output of flashrom -v is "flashrom v0.9.4 : 4169bc8 ...". The first time I ran flashrom --wp-disable, I got a message saying the operation FAILED with error=1. At that point I took the board apart again and cleaned the write-protect screw hole with q-tips dipped in rubbing alcohol. When I reassembled the Chromebook and tried again with flashrom -V --wp-disable, the last few lines I receive are: w25_set_srp0: old status: 0xb8 w25_set_srp0: new status: 0xb8 w25q_disable_writeprotect(): error=1. No -i argument is specified, set ignore_fmap. FAILED restore_power_management(): Power management enabled As you can see, I can't seem to disable write protection on this chip. I'm running stock ChromeOS. Any idea what I might be doing wrong? Thanks in advance.

Serprog/Arduino flasher
by Eric Marks 14 Dec '13

14 Dec '13

I successfully used a Arduino Uno as a serprog programmer to program a SST25VF016B with Flashrom 0.9.5.2-r1517 on Ubuntu. I had tried hooking the eeprom up to the Arduino via level shifting via resistors, and then via level shifting mosfets + resistors, and finally via a level conversion chip, but none of them worked reliably. I finally converted my Ardruino Uno to 3.3v by replacing the regulator. http://learn.adafruit.com/arduino-tips-tricks-and-techniques/3-3v-conversion This was a much easier solution, and it worked reliably. Once converted to 3.3v, no extra components are needed. Just wire the eeprom directly to pins 10,11,12,13, GND, and 5V (which is now actually 3.3v). Remember, three pins of the eeprom go to 3.3v. I still had to slow the UART speed down to 115200 for the Arduino sketch on the Uno, and while reading took a normal amount of time, it took several hours to program the chip. I used -VVV to enable very very verbose output to monitor the progress. Could someone update the wiki with this information? It didn't look like there was any place to sign up and edit it myself. http://www.flashrom.org/Serprog/Arduino_flasher Thanks for helping me save a server!

I'm not subscribed to the list, but I thought I'd report a successful flash of this motherboard. Thanks! Attached (assuming it isn't filtered) is the -VVV output from the flash. -- Mark Nipper nipsy(a)bitgnome.net (XMPP) +1 979 575 3193 - "We enter into life naked and howling, covered with blood.

I can be there on Saturday, but my availability will be spotty (read: maybe 3 hours) on Sunday. If someone commits to taking care of the booth on Sunday, I'll submit a booth application.
