Building EDK2 based firmware for MinnowBoard

Published at April 3, 2018 · Bartek Lew · 2 min read

Building EDK2 based firmware for MinnowBoard There are some options to build firmware for MinnowBoard, a Bay Trail based SBC (Single Board Computer) from Intel. We prefer usually coreboot as simplest and fastest, open source solution, but sometimes we want to have UEFI interface. UEFI itself doesn’t cover whole boot procedure, so its open source reference implementation, EDK2 is not enough to build firmware for hardware plafrorm, we need to provide PI (Platform Initialization) phase implementation....

Building UEFI based firmware on MinnowBoard

Published at March 28, 2018 · Bartek Pastudzki · 8 min read

Building coreboot on well supported platform such as Bay Trail is quite straightforward task, however we need to remember about some things in order to have coreboot working. First of all we need to provide up-to-date microcode and FSP (Firmware Support Package), which are not included in coreboot source tree and coreboot build system won’t complain about it. Second thing is that Bay Trail has TXE firmware on the same ROM as boot firmware so we have to make sure that we won’t corrupt it because it would brick the platform....

Minnowboard Turbot remote firmware flashing with RTE (Remote Testing Environment) Introduction Work related to a hardware carries some restrictions which don’t occur when working only with a software. One of them is a limited number of devices. This one may cause a problem with a accessibility to the platform. The limited number of users could slow development and testing. What is more work with a hardware requires a minimal knowledge of the theory of circuits and signals to eliminate platform damage by a user....
