I guess Astralix know about them, he said he disassembled boot code
<naobsd>
ah, I didn't know he read that gist, what I said is he (probably) knows same thing

hmm. I still have no idea about trailing extra 2 bytes which is added to ddr/usbplug control transfer, and no idea about crc for writing via bulk transfer
<naobsd>
for former, there might be answer in bootrom, for latter, there might be answer in RK official .exe
<fonix232>
well I'd preferably replace the whole thing with u-boot
<fonix232>
and fastboot
<fonix232>
for flashing
<naobsd>
"replace whole thing" sounds very good, but personally I'm feeling "loading u-boot instead of kernel" may be enough
<naobsd>
anyway, to make working u-boot will be hard
<naobsd>
(for me)
<naobsd>
there is no information about nand controller

<fonix232>
yes I know :\
<fonix232>
that's the hardest part
<fonix232>
hopefully we can convince Rockchip to release the information
<naobsd>
for me, it's difficult to say "it can" for everything which doesn't exist now...

yes, I know
<fonix232>
and understand
<fonix232>
oh well
<fonix232>
open bootloader is a nice dream, but it's sooo far
<fonix232>
would be a lot easier to boot any generic linux on it
<naobsd>
I can boot any linux kernel with stock(closed) bootloader
<naobsd>
so I have interest to do something in kernel
<naobsd>
(un?)fortunately, CWM/adb/flash_image runs nicely, so I can use them to flash images to nand
<naobsd>
I'm sure it's not so nice for open source things, but I have no skill/time to do everything open ;)
<naobsd>
"u-boot instead of kernel" will be good for me. I heard mmc is DesignWare, I guess there is some code for u-boot

<fonix232>
and how would u-boot instead of kernel help?
<fonix232>
you still need the kernel itself
<fonix232>
but by replacing the bootloader with u-boot, we would have a more secure way of flashing
<fonix232>
without killing the device if misflashed
<fonix232>
and there would be no need for the stupid RKAF images
<fonix232>
also by any chance do you know the Ugoos UM2?
<naobsd>
"u-boot instead of kernel" == "replace kernel with u-boot"
<naobsd>
I can't find any difference about what u-boot gives
<naobsd>
I have no idea why RKAF is the problem, it's not mandatory thing even for now
<fonix232>
if you want to update the bootloader, then yes
<fonix232>
and yes,I get it
<fonix232>
but u-boot is not a kernel
<fonix232>
it is a bootloader
<fonix232>
what you just said was like "oh I'm gonna replace the kernel with grub"
<fonix232>
RKAF is a problem because every damn new chipset comes with a new chip ID, and just recently with the 3168, they randomized it
<fonix232>
I have a friend with a 3168 tablet,and she cannot make a factory flashable image because of this crappy change
<naobsd>
I don't know about RK3168, but RKAF (and RKFW) image are not mandatory to flash images to device
<naobsd>
"replace kernel with u-boot" == I'm talking about bootloader, not kernel.
<fonix232>
yes you can use the RKDevTool to flash partitions
<fonix232>
but that still won't be able to flash the param file properly
