Verdin AM62 Module
==================
- SoM: https://www.toradex.com/computer-on-modules/verdin-arm-family/ti-am62
- Carrier board: https://www.toradex.com/products/carrier-board/verdin-development-board-kit
Quick Start
-----------
- Get the binary-only SYSFW
- Get binary-only TI Linux firmware
- Build the ARM trusted firmware binary
- Build the OPTEE binary
- Build U-Boot for the R5
- Build U-Boot for the A53
- Flash to eMMC
- Boot
For an overview of the TI AM62 SoC boot flow please head over to:
