Intel Bay Trail read report
by Antonio Ospite 28 Feb '15

28 Feb '15

Hi, I've got a Bay Trail tablet[1] and I tested flashrom on it, see the attached report. As reported in [1] I compiled flashrom statically on my host and then executed it under Android on the target. Reading the SPI flash works fine, is it safe enough to test writing too? I ask because accessing the SPI flash physically for external programming can be a little more inconvenient for a tablet. Another question: would it be possible to use flashrom to only reset the firmware _settings_, while leaving the code untouched? Thanks, Antonio [1] http://ao2.it/110 -- Antonio Ospite http://ao2.it A: Because it messes up the order in which people normally read text.

So we should remove the current limitation after some more testing... I'll leave this email here as an reminder. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Abit KN9 board enable method, lspci -nnv
by Georg Sauthoff 28 Feb '15

Hi, as discussed on IRC (#flashrom) today, current flashrom trunk fails writing the flash chip on an Abit KN9 Ultra/SLI board. Reading works, though. The failure message is: flashrom/trunk/flashrom --programmer internal -c Pm49FL004 -w M520A_23.BIN flashrom v0.9.8-rc1-r1885 on Linux 3.2.0-4-amd64 (x86_64) flashrom is free software, get the source code at http://www.flashrom.org Calibrating delay loop... OK. Found chipset "NVIDIA MCP55". Enabling flash write... OK. Found PMC flash chip "Pm49FL004" (512 kB, LPC, FWH) mapped at physical address 0x00000000fff80000. === This flash part has status UNTESTED for operations: ERASE WRITE 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. Please include the flashrom log file for all operations you tested (see the man page for details), and mention which mainboard or programmer you tested in the subject line. Thanks for your help!

Looking for another erase function. No usable erase functions left. FAILED! Uh oh. Erase/write failed. Checking if anything has changed. Reading current flash chip contents... done. Good, writing to the flash chip apparently didn't do anything. This means we have to add special support for your board, programmer or flash chip. Please report this on IRC at chat.freenode.net (channel #flashrom) or mail flashrom(a)flashrom.org, thanks! It fails because the chip is write protected, by default. It turns out that the board enable method for the Abit KN9 Ultra is the same as for the Abit KN8 Ultra - which is already included in flashrom (nvidia_mcp_gpio2_lower()). That means that I could successfully flash that chip multiple times with flashrom using that board enable code.
