hello all I have a AC8350 (BX09) which is maybe a K-R42 and was wondering what people knew about the linux boot process and debugging it on linux, for example do people know where I casn attach a serial consol?
<oms101>
my mission is to try and get fedora running on it, ideally with wayland but xorg would be fine too
<oms101>
I also want to compile some kernels for it
<AstralixNB>
Hmm... but that should be working y just using some existing images
<oms101>
I got picuntu runnign on it and was quiet impressed
<oms101>
but sadly no network
<AstralixNB>
yes, so if you got that step working you're in :)
<AstralixNB>
oh. Hmmm...
<AstralixNB>
There are several different options how to run a mac i/f with RK
<AstralixNB>
i.e. they allow to configure one GPIO to deliver the 25MHz clock to the PHY so it doesn't need any extra crystal
<oms101>
yes I will try again soon (maybe today, though tonight I am off to the CCC looking for lifts to FOSDEM)
<oms101>
but I woudl like to get my own kernel booting with network before the weekend
<oms101>
sounds like with the GPIO being re purposed for such things the networking in rk3188 chips is very problematic
<oms101>
(next couple of hours I will focus on moving moneys around and paying bills then comes then next hack time)
<AstralixNB>
may be I am still in here

How can I change a parameter in my tablet (rk2928) without updating whole system via RK Batch Tool?
<pfcode>
Is there any easier way to do that? Somekind of flasing only parameter value to specific address?
<oms101>
dear pfcode , I am new here too so dont know, I have tried and failed, simply flashing the parameter file has led me to need to erase the idb to get thigns back
<pfcode>
maybe we should try to decompile RK Batch Tool to get know about that :D
<pfcode>
hm..
<pfcode>
but it's not so crazy idea
<oms101>
well Im a begginer
<oms101>
but
<oms101>
I belive its possibel to trap usb traffic
<oms101>
I think this might be just as easy (hard)
<oms101>
I think to do this its easiest to do with the vm layer
<pfcode>
yes
<pfcode>
but
<oms101>
but since i have never done it
<pfcode>
i'm thinking about using an arduino board as a 'proxy'
<oms101>
but google translate will help you read it
<pfcode>
yeah, i know
<oms101>
seems some one has been reversing the batch format
<pfcode>
he wasn't reversing the flashing process, but only the bootloader code
<oms101>
I had a look at the parameter file
<oms101>
it seesm to be soem text with a header
<oms101>
followed by some blank characters
<oms101>
I was gonna nock up a small python scritp to make the header and trasnlate text
<oms101>
I found with a hex editor I coudl change paramters
<oms101>
and they stayed
<oms101>
but I did not change the length of the parameter string
<oms101>
thats my next plan
<oms101>
but I am plaing with an rk3188
<pfcode>
you don't have to change its length
<pfcode>
you can use as many space characters as you need to fill the space
<pfcode>
linux kernel will skip it between arguments
<oms101>
so I took out the paramters file
<oms101>
backed it up
<oms101>
hex edited
<oms101>
and reflashed
<pfcode>
did it work?
<oms101>
is that what you are trying to do ?
<oms101>
I changed the name of the SDK
<oms101>
I will have to confirm (in about an hour)
<pfcode>
you don't have to.
<oms101>
but as far as I remeber I changed the SDK name
<pfcode>
i'm trying to change the parameter to modify the partitions
<pfcode>
i'd like to have one, big partition for system on nand
<pfcode>
and sdcard
<pfcode>
of course, i know i also need the boot partition
<pfcode>
another question, the last time I was flashing it with Arch Linux (chrooted from boot environment) I ran xorg, gnome3, wifi successfully
<oms101>
I am on a simlar path, but I never succeeded in changign the partitions sizes and making it boot
<pfcode>
but I couldn't get the mali400 to work with acceleration
<pfcode>
and I haven't found the drivers to the touchscreen
<oms101>
I tried flashing it with picuntu and never got wifi or LAN but was super impressed with the performance (even on X) though 3d acceleration was missing

I am afraid I dont knwo about such things
<oms101>
I am using a AC8350 (BX09) and it has no screen just HDMI and composite out
* pfcode
is copying a folder with rom data I was working with a few months ago :>
eebrah_ has quit [Ping timeout: 260 seconds]
<karlp>
yeah, I'm still struggling to get a viable screen connected
eebrah_ has joined #linux-rockchip
<karlp>
getting both a usb connection for debug and flashing as well as a hdmi screen I can see at somewhat the same time and inputs is tedious
<karlp>
got a hdmi-vga adapter that works with another hdmi device, but not with my rk3066 stick :|
