rpi_3_defconfig is the 64 bit aarch64 config and it's for all models of the 3B, so the original, the 3B+ and the CM3, the rpi_3_32b_defconfig is for 32bit ARMv7 booting so running a 32bit OS on all variants of the 3. > [2] Anyone managing to build u-boot for the RPi 3b+? Yes, the one you built above will detect both models, the rpi_3_32b_defconfig config is also for both models but is for 32 bit OS (32b) _______________________________________________ boot-architecture mailing list [email protected] https://lists.linaro.org/mailman/listinfo/boot-architecture
