For Microchip I had to revert commit ec7c2a107a59a60079eff3308e791a3441231f2e. It seems there is a Kconfig naming conflict. I use: CONFIG_BUILTIN_DTB_NAME="pic32mzda_sk" CONFIG_BUILTIN_DTB=y CONFIG_MIPS_NO_APPENDED_DTB=y Furthermore I had to recognize that ethernet is not working in Linux, just in u-boot. But that is unrelated to the patches. You can add my Tested-by: Waldemar Brodkorb to the patch series. best regards and thanks very much, Waldemar --+d3DKV7c4yq6zleZ Content-Type: text/plain; charset=utf-8 Content-Disposition: attachment; filename="rb532.txt" [ 0.000000] Linux version 7.0.0-rc5+ (wbx@fluor) (mipsel-openadk-linux-uclibc-gcc (GCC) 15.2.0, GNU ld (GNU Binutils) 2.46.0.20260210) #1 Fri Mar 27 20:44:56 CET 2026 [ 0.000000] CPU0 revision is: 0001800a (MIPS 4Kc) [ 0.000000] User-defined physical RAM map overwrite [ 0.000000] Primary instruction cache 8kB, VIPT, 4-way, linesize 16 bytes.
