This page describes how to run coreboot on the Portwell PQ7-M107.
PQ7-M107 are assembled with different onboard memory modules: Rev 1.0 Onboard Samsung K4B8G1646D-MYKO memory Rev 1.1 and 1.2 Onboard Micron MT41K512M16HA-125A memory Rev 1.3 Onboard Kingston B5116ECMDXGGB memory
Use 'make menuconfig' to configure onboard memory manufacturer
in Mainboard menu.
This board currently requires: fsp blob 3rdparty/fsp/BraswellFspBinPkg/FspBin/BSWFSP.fd Microcode Intel Braswell cpuid 1046C4 version 410 (Used pre-built binary retrieved from Intel site)
The main SPI flash can be accessed using flashrom.
The system has an internal flash chip which is a 8 MiB soldered SOIC-8 chip. This chip is located on the top middle side of the board. It's located between SoC and Q7 connector. Use clip (or solder wires) to program the chip. Specifically, it's a Winbond W25Q64FW (1.8V), whose datasheet can be found here.
