In that case it's +not needed to extract blobs from vendor firmware and internal flashing is +sufficient. +* To flash the whole chip (e.g. to disable ME) blobs are needed to build +coreboot. Blobs can be extracted with util/ifdtool from 4MiB full dump image +(see below). Its recommended to include the VGA BIOS as well (4MiB write only). +Kconfig is prepared already if it gets enabled (path and 8086,0102). +``` +coreboot/3rdparty/blobs/mainboard/msi/ms7707 +├── descriptor.bin +├── gbe.bin +├── me.bin +└── vgabios.bin +``` +* Never write a full 4MiB image if blobs are not included. The generated +coreboot.rom file is always 4MiB but the 2MiB flash command below will only +flash the last 2MiB (BIOS) block. +* The J1-Jumper sets the 'Flash Descriptor Override Strap-Pin' and enables +full 4MiB access for internal flasher (read and write). +* **Write BIOS-range** (2MiB) with J1-Jumper=off (as on picture/default + position): +``` +flashrom -p internal:ich_spi_force=yes --noverify-all --ifd -i bios -w coreboot.rom +``` +* **Read full dump** (4MiB) with J1-jumper=on: +``` +flashrom -p internal -r original.rom +``` +* **Write full dump** (4MiB) with J1-Jumper=on: +``` +flashrom -p internal -w coreboot.rom +``` +* After successful flashing turn main power off, wait some seconds to drain +the capacitors, pull the battery and set the JBAT (clrcmos) jumper for some +seconds. Setting the jumper alone is not enough (the Fintek is VBAT backed). +Put all back in place and restart the board. It might need 1-2 AC power cycles +to reinitialize (running at full fan speed - don't panic). +* External flashing has been tested with RPi2 without main power connected. +3.3V provided by RPi2. Read more about flashing methods [here](https://doc.coreboot.org/flash_tutorial/index.html). +* In case of going back to proprietary BIOS create/save cmos settings as early +as possible (do not leave BIOS on first start without saving settings). +The BIOS might corrupt nvram (not cmos!) and leave the system in a dead state +that needs an external flasher to revive. If stuck, reset the Fintek (see +above) and restart the system several times and/or try setting J1 to +temporarily disable ME. + +![](J1-flash-protect.jpg) + +* The JSPI1 header (5×2 2.0mm pitch pin header) for external flashing is +directly connected to the flash chip.
