Oh, a difference: $ tools/mkimage -n rk3288 -T rksd -d tpl/u-boot-tpl.bin idbloader.img && \ cat spl/u-boot-spl-dtb.bin >> idbloader.img
I'm using the idbloader.img that u-boot automatically spits out. $ tools/mkimage -n rk3288 -T rksd -d tpl/u-boot-tpl.bin idbloader-manual.img Image Type: Rockchip RK32 (SD/MMC) boot image Data Size: 20480 bytes $ cat spl/u-boot-spl-dtb.bin >> idbloader-manual.img However.. the generated idbloader-manual.img from the commands above is identical to idbloader.img that u-boot produces compared with md5sum. Are you writing the following? sudo dd if=idbloader.img of=/dev/sdd seek=64 sudo dd if=u-boot-dtb.img of=/dev/sdd seek=16384 (where /dev/sdd is a MicroSD card) These should be enough to get into u-boot at startup... correct? I'm not missing some requirement of u-boot.bin on a FAT32 partition or something? -- Alex September 23, 2019 8:31 AM, "Jonathan Gray" <j...@jsg.id.au> wrote: > On Mon, Sep 23, 2019 at 01:06:35PM +0000, Alexander von Gluck IV wrote: > >> Ok, looking for differences now.. >> >> * Older Tinker Board?
