<Tony_>
(2) RK_RK616 is for machine self.
<Tony_>

I was just a bit ... shocked as after the high postage price there where unexpected high taxes on the delivery bill and then after unpacking and installing the board did do nothing...
<AstralixNB>
But it looks like it doesn't start any LED and the preinstalled Android doesn't show any logoshow and then it didn't like my TV...
<AstralixNB>
But then, after seeing the blue light flashing, disconnecting and reconnecting the TV, Android is showing up...
<AstralixNB>
So it just needed some patience...

Ok, after the shipped Android worked, I flashed lubuntu image... both don't work at all.
<AstralixNB>
the 0930 image crashes as the kernel tries to init DRAM
<AstralixNB>
the 0809 crashes as uboot isn't satified with dtb...

<AstralixNB>
hehe... I thought it works the other way round... I get a board with working images and then I program non working ones...
<mmind00>
sounds very much like the issue with the mmu ... Rockchip fixed that with the uboot in the rkchrome-repo, but I guess it never made it into a bsp
<mmind00>
maybe the firefly guys had upgraded uboot on their dev-boards but forgot that the ones shipped out had old loaders
<AstralixNB>
no idea... But I am at the company... A binary image would be great
<AstralixNB>
Can't find dts node for fuel guage cw201x
<AstralixNB>
Is probably not for this board
<AstralixNB>
So the board revision (even not printed on the PCB) must be a v0930
<rperier>
ohh yeah, indeed it might explain your issues
<rperier>
(I am talking about the bootloader bug)

But it is complicated to write in their forum as the editor is doing funny things with the line spacing and such, but the symbols are labeled with chinese explanations...
<AstralixNB>
mmind00, the patch you posted is for the kernel? Are you aware of any uboot that takes care of correct MMU handling?
<mmind00>
yep ... Rockchip fixed that in may or so after I reported the issue ... github/rkchrome/uboot is doing the right thing for example
nighty-_ has joined #linux-rockchip
<AstralixNB>
I check that out and try to bake it
<mmind00>
and therefore also naobsd's (currently missing) fork is fine
<AstralixNB>
yes, both are missing... naobsd and his repo...

Hi naobsd, nice to see you!

<AstralixNB>
naobsd, did you have the current uboot for RK3288 with the fixed MMU setup?
<naobsd>
I'm not sure which file does mmu setup in u-boot
<AstralixNB>
Did you remove the repo for uboot?
RayFlower has quit [Read error: Connection reset by peer]
RayFlower has joined #linux-rockchip
<naobsd>
temporary removed, I need to do some conversion
<naobsd>
same source (but modified history) will be available
naobsd has quit [Quit: Page closed]
<AstralixNB>
no problem. I clone the firefly repo and check what's inside. For the MMU thing, ask mmind00 for some hints, I catch up after the pizza that just arrived :)

how it is possible to deliver to non-working software like this one... seriously... (for a company, the context is different when this is a FLOSS project driven by a community)
<rperier>
I mean, as you said only the stock uboot shipped with your device worked... it sucks seriously

kenguru: what do you mean by wideband?
<field^Mop>
ok, afk again.. sorry
<BorgCuba>
field^Mop, thanks for the info
<BorgCuba>
the weired thing is that it worked for quite some time
<BorgCuba>
i tested with ft232 and pl2303
<kenguru>
no, but same usb-com adapter, didn't read the whole article is the drivers only faulty or the device unreliable itself. I Opened again that page and well it seems they are just discussing about the ubuntu support for it.
<BorgCuba>
maybe I try a level shifter
<kenguru>
