Flashing
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.
