What we have done?
Our open-source firmware trainings are typically structured into two parts. A theoretical and a practical hands-on part. Those require hardware to work on. Therefore we ported coreboot on the AAEON UP² computing module.
We implemented the following additional features:
- TPM CRB interface driver
- Intel Platform Trust Technology (iTPM) driver
- Verified and Measured Boot functionality
- Serial Console (UART0) support
- Tested with LinuxBoot or Linux payload
Why is it important?
If it comes to open-source firmware trainings, it is important to have a small form factor platform which is affordable but supports a rich set of features required within the workshop.
We decided to go with the UP² because it has support for open-source firmware like TianoCore or slimbootloader. So we could gain better insight how things work internally on the Intel Apollolake platform.
It shows again how cost-efficient hardware platforms can be ported even without datasheets or schematics. Going the open-source firmware road is an essential path in eliminating high cost firmware development and creating transparency for customers.
