This does not answer the concern - it's not the same SoC. The most generic compatible denotes the most common part. I would argue that instruction set and architecture are the most important differences. None of ARMv8 SoCs (SoCs, not CPU cores) have "arm,armv8" compatible and you went even more - you combined two architectures in the most generic compatibles. > >> >>> Using same SoM and Carrier board? >> >> It's like saying PC with x86 and ARMv8 board are the same because they >> both use same "PC chassis". > > What I meant is board based on Family SoC(R9A07G043) that is either based on ARMv8 or > RISC-V cpu architecture. I don't see this related to the topic at all. What board do you use, does not matter. The board does not change the fact these SoCs have entirely different architecture - ARMv8 and RISC-V.
