The AM62x LP SK board is similar to the AM62x SK board, but has some significant changes that requires different device tree.
The differences are mainly:
- AM62x SoC in the AMC package that meets AECQ100 automotive standard.
- LPDDR4 versus DDR4 on the AM62x SK.
- TPS65219 PMIC instead of discrete regulators.
- IO expander pin names are wired differently.
- Second ethernet port is currently disabled as the boards do not have the part physically installed.
- OSPI NAND vs OSPI NOR.
- No WLAN chip instead a SDIO M.2 connector.
