Part Number: AM6421
Other Parts Discussed in Thread: AM6422
Hardware :
-
Target board: Custom AM6421B board
-
Base image source: AM6422 EVM Buildroot image (used as base for our custom board)
-
TI reference board: AM642 EVM
Tool Chain :
Buildroot: 2026.02
We are using a Buildroot image that was originally built for the AM6422 EVM (with DDR4 2GB) as our base. We are adapting it to run on our custom AM6421B board (with LPDDR4 512MB).
We created and are using a custom LPDDR4 dtsi for our board
