<RaYmAn>
probably because the video driver is more or less a copy of the sun4i driver
<RaYmAn>
:)
<RaYmAn>
also, the Mali GPU probably still supports HDMI, it's just not hooked up to the stuff required to expose it

I found some board at work with an USB B-Socket, an FTDI and a digital insulator on it
<The-Compiler>
so I soldered wires and a connector to the IC pins and I hope it works :P
<calris>
that's a bit hard core :)
<Triffid_Hunter>
heh http://triffid-hunter.no-ip.info/100_1698.JPG <-- arduino modded for 3v3 operation, have used as impromptu 3v3 serial cable many a time just by pulling the chip
<mnemoc>
because of the lack of PIOs A13 needs to (ab)use the PMU
<jquip>
anybody got linux working on the h6 net book??
<mnemoc>
all A10 devices are mostly the same beside the script.bin config
<jquip>
well apparently !! I have a tablet for which I have things working fine.. Changed the script.bin (taken from the netbook).. but kernel doesnt seem to load at all.. no kern.log, dmesg...nothing in var/log...
<jquip>
and I dont have a serial logger to check the u-boot o/p
<mnemoc>
never use an script.bin from a different device
<jquip>
sorry let me rephrase (The tablet with its own script.bin works fine.. the netbook when used with the same sdcard and its own script.bin does not.)
<mnemoc>
some devices have troubles with NO_HZ and PREEMPT. try disabling those.... but having a uart/usb is still critical
<mnemoc>
if the laptop has the OTG port exposed you can test using a fel card and see if that boots
<jquip>
does the u-boot for the net-book differ from the tablet? the boot process seems routed to the scdcard... Android doesnt boot... but then it doesnt reach to a point where the kernel loads..
<jquip>
hmmm.. let me check on the OTG..
<mnemoc>
it can also be that the dram initialization of the device isn't compatible with the code in the public uboot

wait what, is the Mele A1000 or the A2000 newser?
<The-Compiler>
newer even
<jquip>
can any lead be found by looking at the android partitions on the config...(sorry to ask) I just have to go get myself a usb/uart then..
<mnemoc>
The-Compiler: A2000 is newer, but both have the same PCB
<mnemoc>
The-Compiler: mele has made 4 devices with the same board and only different case already
<The-Compiler>
okay, just had a source saying the A2000 is older, kinda confused me
<The-Compiler>
haha, I know :D
<mnemoc>
A1000, A2000, A100 and the latest A3600 (with real antenna!)
<The-Compiler>
haha, the 3600 looks ugly :D

heh, I wonder what all this "TTL to UART converter drawing too much current" thing is about
<The-Compiler>
the board I use has an electronical insulator on it after the FTDI (bummer I forgot the scheme at work) so that might draw some current and I can't simply disconnect the 3V3 pin
<cat1>
hmm, got 3.6 kernel working on my mk802 somehow.. had to comment reserve_fb however.
<cat1>
does anybody know what is this script about?
<cat1>
3.6 kernel freezes when it tries to access that.
<mnemoc>
that's a known problem in the 3.4 branch too
<mnemoc>
but there it doesn't freeze, it simply reads zeros
<mnemoc>
in the mean time comment out the "disabled" part and just assume the script.bin wants to enable all features
<mnemoc>
it's pretty frustrating....

it looks like there's a variable there called ?pair that it doesn't seem to be digging

The-Compiler: havy you tried different sdcard?

have..
<The-Compiler>
hm, not since I have the TTL to USB adapter
<The-Compiler>
same thing with a different card.
<rm>
The-Compiler, it does work in Android w/o problems, right?
<The-Compiler>
yes, Android boots fine
<The-Compiler>
and I see the SD card and the FAT32 partition on it
<The-Compiler>
hm, this time it did freeze while detecting the memory
<rm>
I'd get the *.bin file your device has in NAND
<rm>
and decode/examine it

compare with others
<The-Compiler>
hmm, I should be able to get it with Wireless ADB and adb pull, huh?

also, if someone has a statically linked memtest binary for android, let me know

Marex, well, core voltage is obviously wrong which is a step forward I think.
<hno>
but got a bit mixed results clocking the chip at standard boot frequency.
<hno>
and don't understand how the A10 SPL can work, it should have the same power issue.
<hno>
at least it's not u-boot issues I am fighting but mostly lack of knowledge of the chip in question.
<hno>
or chips actually, need to digest the AXP209 PMU a bit.

Finally found some time to take the plunge, going to strap Puppy on SDcard for MK802.
<hno>
Marex, and JTAG debugging of u-boot turned out very easy when u-boot at least starts to the command prompt. The relocation address is then easilly printed by bdinfo.
<hno>
The-Compiler, what board are you using?
<RaYmAn>
hno: so it worked with that exact offset? Or did you have to add e.g. 0x30?
<The-Compiler>
hno: Mele A2000 (or do you want me to be more specific?)

hno: vim arch/arm/lib/board.c ... s/debug/printf/ ... and fish the address from there ;-)
<hno>
RaYmAn, it works with that exact address (it is not an offset).
<RaYmAn>
Marex: you could just, you know, enable debug macros rather than rewrite c files ;)
<hno>
The-Compiler, Mele should be pretty stable on any setup..
<RaYmAn>
hno: it's an offset from memory base ;)
<Marex>
RaYmAn: this is faster :p
<RaYmAn>
Marex: not really :P
<Marex>
RaYmAn: and yea, I know ... I wrote debug_cond() and redid debug() some time ago ;-)
<The-Compiler>
hno: well, I get random freezes at random places when trying to boot anything except Android
<Marex>
I remember it more than well
<hno>
RaYmAn, no, it's the raw address.
<RaYmAn>
hno: nitpicking :P It's an offset from address physical address 0! :P
<hno>
But memory base is 0x40000000
<hno>
all sorts of wierd stuff before that.
<The-Compiler>
as soon as mum stops watching that stupid TV show I can get the *.bin off nanda
<The-Compiler>
both of my PC screens don't seem to like the mele
* RaYmAn
ponders where the hell he has a vga cable
<hno>
The-Compiler, if you have a debug uart then just mount /dev/nanda somewhere and copy the bin to an sd card. Or pick up the copy mnemoc have already collected at github.
<gimli>
jelly-home: +1
<The-Compiler>
hno: well, if I had some normal *.bin it would boot... or there is something else going on
<The-Compiler>
hno: I assume I don't get a shell via UART in android, or do I? :o
<hno>
I get a shell on mine.
<hno>
no prompt, but there is a shell listening.
<The-Compiler>
oh.
<Marex>
hno: export PS1 ;-)
<hno>
Not sure if the HDMI display problems with the mele is due to color scheme (YCbCr instead of RGB) or due to HDCP protection being enabled by default.
<hno>
Marex, I only run Android when booting fails so it falls back on NAND...

so I have script.bin/script0.bin/magic.bin - which one is the relevant one?

script.bin (script0.bin is a copy)
destinal_zzz is now known as destinal
<The-Compiler>
so that wasn't it... I don't find anything on how I should run memtest on the Mele.
<The-Compiler>
I still suspect it's corrupted RAM
<hno>
The-Compiler, do Android also have problems booting?
<The-Compiler>
no, Android boots fine
<hno>
in the last days while playing with A!3 I have discovered some things which is clearly done wrong in u-boot-mmc which may cause system instability.
<hno>
until linux kernel gets around and configuring things proper.

cpu core voltage is set wrong and some other small details.
