i have a question
<ritech>
hi all
<ritech>
want change nand flash to emmc flash on rk3188
<ritech>
need to change ubootloader?
<naobsd>
ritech: generally flash memory is soldered, it cannot be changed
<ritech>
why not ?
<ritech>
i change nand to emmc , easy flash , but boot problem
<ritech>

[mmc1] [ 3.837916] .Line4036..The End of SDMMC-probe Ver.6.07 The last modify date is 2013-1
<ritech>
this is my log
<ritech>
it show mmc0:0001 016ge2
<ritech>
but mmcblk0 : p1 p2 p3
<ritech>
wrong
<ritech>
i think mmcblk0: p1(boot) p2(bootargs) p3(hwconfig) p4(loader) p5(recovery) is right
<ritech>
so maybe loader.bin wrong , cant flash partition
<naobsd>
why do you think "mmcblk0: p1(boot) p2(bootargs) p3(hwconfig) p4(loader) p5(recovery) is right"?
<naobsd>
how did you make partition on emmc?
<ritech>
p1(boot) p2(bootargs) p3(hwconfig) p4(loader) p5(recovery) show on my nand flash boot log
<ritech>
first i use AndroidTool 2.3 flash loader.bin on maskrom mode , then find a loader device , upgrade android.img , reboot
<ritech>
on my nand flash , all be ok, but change to emmc flash , boot failed , jump to recovery mode
<naobsd>
if recovery mode works, then hardware is working
<naobsd>
what's "flash boot log"?
<ritech>
i think loader different between on emmc and nand
<naobsd>
you don't any Rockchip support to do it? there should be docs and loader files
<naobsd>
you don't _have_ any ...
<ritech>
Recovery system v4.4.0 E:failed to mount /metadata (No such file or directory) mount cache fail,so formate... format '/dev/block/platform/emmc/by-name/metadata' to ext4 filesystem executing '/sbin/mke2fs' Could not stat /dev/block/platform/emmc/by-name/metadata --- No such file or directory
<ritech>
yes , iknow recovery will work , but show this log
<ritech>
i dont have rockchip support , i just buy firefly and radxa
<naobsd>
well
<ritech>
Starting recovery on Sat Jan 1 12:06:03 2011
<naobsd>
what you are talking (mmcblk, recovery) is the things _after_ loader. I cannot see any detail about eMMC/loader things
<naobsd>
loader works very initial stage only
<naobsd>
if something like recovery is running, it means that loader worked well
<naobsd>
can you explain "p1(boot) p2(bootargs) p3(hwconfig) p4(loader) p5(recovery) show on my nand flash boot log" more?
<naobsd>
and can you explain how did you make partition(=parameter)?
<naobsd>
and detail about loader.bin and android.img
<naobsd>
important details are not explained yet
<ritech>
ok
<ritech>
i find a new problem , i cant format my emmc flash throught androidtools 2.3
<ritech>
but nand flash format is ok

I'm trying to boot a rock2 square using mainline uboot and a kernel. I wonder if anyone's found a working example of this or a guide somehwere, or has some debuging tips.
<Sandy>
er, rock2=3288, and linux kernel. I think i'm not getting uboot to load my kernel image, initrd, and dtb right
