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.
