Proprietary components status

  • CPU Microcode (optional)
  • ME(Management Engine) => you do not have to touch it (just leave it where it is)
  • EC(Embedded Controller) => you do not have to touch it (just leave it where it is)

GPIO layout

This information should not be considered reliable in any way, shape or form

  • GPIO57 - OUT - controls..

General Purpose Events layout

  • GPE? - EC SCI
  • GPE? - EC SMI

Flashing

Location of the SPI chips

T530 has 2 flash chips of 8M and 4M. They're concatenated to one virtual flash chip of 12M which is itself subdivided in roughly in 4 parts:

  • Descriptor (12K)
  • ME firmware (5M-12K)
  • System flash (7M)

ME firmware is not readable. Vendor firmware locks the flash and so you need to flash externally (unless until someone figures out a way around it).

Proceeds as follows:

  • Turn off your laptop, remove battery and AC adapter.
  • Remove the keyboard.
  • Connect your external SPI flasher to the top SPI chip which is under palm resting space, on left side of the board. It's a 4M chip. IF you've chosen CBFS_SIZE 4M or smaller that's the only chip you need to reflash.

I recommend using SOIC clip. Depending on the flasher you use, you may have to use separate 3.3V source. Make sure not to feed more than 3.3V ot the chip. I used buspirate as flasher and 3.3V power lines from another computer.

  • Read the flash. Twice. Compare the files to be sure. Save a copy of it on

external media. 

flashrom -p <yourprogrammer> -r flash.bin
flashrom -p <yourprogrammer> -r flash2.bin
diff flash.bin flash2.bin

If they don't match, do not proceed. If the file is 8M, you're flashing wrong chip, connect to the right one.

  • Write the flash. Since you have to write only top 4M, first split out those 4M:
 dd of=top.rom bs=1M if=build/coreboot.rom skip=8
  • Use flashrom to flash top.rom.

If you have trouble reading the chip successfully, the most common problems are

  • insufficient power supply
  • bad contacts
  • too long wires
  • bad pinout

The cable shipped with buspirate was too long, and needed to be trimmed.
