Portwell PQ7-M107

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.

Flashing coreboot

Internal programming

The main SPI flash can be accessed using flashrom.

External programming

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.

Known issues

  • The PQ7 module contains Q7 connector only. Depending on the carrier serial/video/pcie ports might be available.

Untested

  • hardware monitor
  • SDIO
  • Full Embedded Controller support
