Dear u-boot community, I have a rockchip rk3328 Board here I am trying to boot linux kernel upon. It is a Dusun DSGW-210 which seems to resemble the setup
board=evb_rk3328 board_name=evb_rk3328 Dusun offers a SDK which they claim to be working in their system, the rootfs can be a debian or a buildroot one. I can not compile it (Host needs to be darn old, I got stuck realizing python2 with ftdi libs is required). Reagardeless I want to port their stuff to yocto linux anyway and since the u-boot an kernel config resemble vanilla evb_rk3328 setup and config I thought it should not be too hard. But it is. For me. I used the JeffyCN yocto meta layer, compiled it and flashed the images. And voila, u-boot seems to work fine! When U-boot starts the kernel I get "Synchronous Abort" handler, esr 0x02000000 The output looks this way: => boot Could not find misc partition ANDROID: reboot reason: "(none)" Not AVB images, AVB skip Booting IMAGE kernel at 0x00280000 with fdt at 0x08300000...

What should I do next to further debug the issue? What I especiall wonder is what does "WARNING: could not set reg FDT_ERR_BADOFFSET." mean, is this harmful or leading to the root cause? I have full boot logs for the working Dusun u-boot and my u-boot available, is it from interest or helpful to post them here completely to compare? Also I found one - may be significant - difference: My u-boot says: Model: Rockchip RK3328 EVB MPIDR: 0x80000000 PreSerial: 2, raw, 0xff130000 DRAM: 2 GiB Sysmem: init Relocation Offset: 7da71000 Relocation fdt: 7bc664a8 - 7bc67ce2 CR: M/C/I Using default environment The Dusun u-boot says: Model: Rockchip RK3328 EVB MPIDR: 0x80000000 PreSerial: 2, raw, 0xff130000 DRAM: 2 GiB Sysmem: init Relocation Offset: 7da71000 Relocation fdt: 7bc664a8 - 7bc67ce2 CR: M/C/I Using default environment Is the difference in "Relocation Offset" my problem? Other Addresses appearing look similair in my u-boot like the Dusun u-boot (kernel load addr, RAM banks added, device tree addresses...).
