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


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


More precisely:
  0x54: 0x00000000 FREG0: Warning: Flash Descriptor region (0x00000000-0x00000fff) is read-only.
  0x58: 0x0bff0500 FREG1: BIOS region (0x00500000-0x00bfffff) is read-write.
  0x5C: 0x04ff0003 FREG2: Warning: Management Engine region (0x00003000-0x004fffff) is locked.

Proceeds as follows:
* Turn off your laptop, remove battery and AC adapter.
* Turn off your laptop, remove battery and AC adapter.
* Remove the keyboard.
* Dismantle machine.
* 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' the only chip you need to reflash.
* Connect external SPI flasher to the 4MB chip.


I recommend using SOIC clip. Depending on the flasher you use, you may have to use separate
Remark: You will need a SOIC clip to connect an external SPI programmer.
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.
=== Flashing Process ===
 
1.) Read out the flash to make a backup '''Twice''', compare to ensure they match and then save a
copy of it on external media:


* 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 flash.bin
  flashrom -p <yourprogrammer> -r flash2.bin
  flashrom -p <yourprogrammer> -r flash2.bin
  diff flash.bin 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, connec to the right one.
'''If they don't match, do not proceed and if the file size is 8M you are flashing the wrong chip.'''
 
2.) Since you have to write only top 4M out of the 12M coreboot.rom, first split out those 4M by:


* 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
   dd of=top.rom bs=1M if=build/coreboot.rom skip=8


* Use flashrom to flash top.rom.
Then 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.

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)
  • GbE firmware
  • System flash (7M)

The 'Descriptor' region locks the flash and so you need to flash externally. ME firmware region is not readable from the CPU.

More precisely:

 0x54: 0x00000000 FREG0: Warning: Flash Descriptor region (0x00000000-0x00000fff) is read-only.
 0x58: 0x0bff0500 FREG1: BIOS region (0x00500000-0x00bfffff) is read-write.
 0x5C: 0x04ff0003 FREG2: Warning: Management Engine region (0x00003000-0x004fffff) is locked.
 0x60: 0x00020001 FREG3: Gigabit Ethernet region (0x00001000-0x00002fff) is read-write

Outline

Proceeds as follows:

  • Turn off your laptop, remove battery and AC adapter.
  • Dismantle machine.
  • Connect external SPI flasher to the 4MB chip.

Remark: You will need a SOIC clip to connect an external SPI programmer.

Flashing Process

1.) Read out the flash to make a backup Twice, compare to ensure they match and then 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 and if the file size is 8M you are flashing the wrong chip.

2.) Since you have to write only top 4M out of the 12M coreboot.rom, first split out those 4M by:

 dd of=top.rom bs=1M if=build/coreboot.rom skip=8

Then use flashrom to flash top.rom.
