When testing Philipp's branch, I was also testing the commit you mention to see if anything broke since I last changed u-boot on my radxa rock. And the above commit started just fine, when starting from an sd-card.
Not sure from which medium you're starting though. But from what I remember Pawel got nand working in his rk3066 series, but that is not yet merged.
I boot from emmc, I will go on hack on it.I finally can boot it with the rock_defconfig. But the way topackage the tpl spl u-boot a little different.
cat ${DIR}/out/tpl/u-boot-tpl.bin > tplspl.bin truncate -s 1020 tplspl.bin sed -i "/^/{1s/^/RK31/}" tplspl.bin cat ${DIR}/out/spl/u-boot-spl.bin > spl.bin truncate -s %2048 spl.bin cat spl.bin >> tplspl.bin Then the tplspl.bin + u-boot.bin should package byboot_merger(tplsplb.in for FLashData, u-boot.bin for FlashBoot) from
rockchip downstream u-boot repo: ./tools/boot_merger ./tools/rk_tools/RKBOOT/RK310BMINIALL.ini
download to emmc by "upgrade_tool ul" command. According to ourbootrom code author, the rk31(maybe include rk30) bootrom has a limitation that the idbblock couldn't accessed by upgrade_tool wl command.
I do have a script handling that [0]. At least for the sd-card variant a simple "openssl rc4" works just as well as the legacy boot_merger :-)

Is there a way to download the out that generated by[0] toemmc/flash? It seems that the upgrate_tool can't access 0x40 of the emmc/nand on rk3188.
you have the @rock-chips.com address, so I'd guess you might even have the better resources to find out ;-) .
In any case, as I said I haven't looked at all at the internal storage on my radxarock so far.
But as the rk3066 and rk3188 are so similar I've added Paweł.
@Paweł: you had uboot starting from nand on your rk3066 board, maybe you could describe how you wrote it to the board so maybe Andy can check if he needs to adapt anything?
Almost all knowledge i had about rk3066 boot process was from Heiko and bootrom disassembly.
Andy, do you have any output on serial console ? (TPL, Uboot-spl or anything else) Can you compile u-boot with #define DEBUG in rk3188_common and send the output? Also you can check size of u-boot tpl (less than 1kb), u-boot spl + tpl (less than sram size on rk3188, i think it's 32KB)? This is important as you wont get any output on serial console if you don't meet this conditions. Also on rk3066 bootmerger FlashBoot size + FlashData size should be less than 256KB (32KB for FlashData, and the rest for FlashBoot, if it's more than 256KB, you get few lines of errors when flashing with upgrade_tool and might have no output on serial console)
One more thing ... to boot from usb with openssl rc4 method on rk3066 i think only one back to bootrom is needed, two if you are booting from nand.
Cheers Paweł
Thanks Heiko
