Seen like some issue on my dts or fdt_get_patch (lib/libfdt/fdt_ro.c) it is returning FDT_ERR_BADSTRUCTURE U-Boot> dm tree ... simple_bus [ + ] `-- aips-bus@02100000 eth [ + ] |-- FEC mmc [ + ] |-- usdhc@02190000 i2c [ ] |-- i2c@021a0000 i2c [ ] |-- i2c@021a4000 i2c [ ] `-- i2c@021a8000 So when I uncomment the "phy-mode" on the dts file [1] I was able to get the proper i2c addr. Couldn't find why the phy-mode node as a corrupt block based on comment from include/libfdt.h about FDT_ERR_BADSTRUCTURE. Simon, any help?
