I've problems with a PL2303 and the mele. I changed the cable and the serial port is configured 115200 8N1 without flow control but the only thing I see when booting is "HELLO! BOOT0 i" (it boots ok)

Now it gets to "HELLO! BOOT0 is starting!" (it boots fine but I don't see anything else at the serial terminal)

check voltages on rx/tx on both ends. 3.3v is low, 0 is high.
<rz2k>
my old ft232 died with constant 0 on rx

<lundman>
sure its not your terminal program
<specing>
hackandfab: what do you have between the pl2303 and the mele?
<hackandfab>
a CDrom audio cable with RX and TX pins inverted and GND to GND
<hackandfab>
I had the 4 colour cable from cubie but CD cable seems better

I wonder what these weird pl2303 out there are ... the one I bought in a retail store 5 years ago is a line driver with +- 13V on its outputs...
<specing>
*dongles
<hackandfab>
my PL2303 doesn't have any capacitor in it (I searched arm-netbook irc log and found mnemoc had problems long time ago with another pl2303)
<hackandfab>
There is a very similar PCB but with a capacitor and a jumper on dealextreme. I've got the one Cubie sells at aliexpress
<specing>
I have nfi how my PL2303's circuitry looks like, it is covered in black plastics
<specing>
it seems so rugged that it would survive a 10m drop

<libv>
pfff.
<libv>
it only works with a usb->ttl uart module.
<mnemoc>
?
<specing>
?
<libv>
you know the serial issues i have been having...
* mnemoc
missed that part of the story
<libv>
and the max2232 module thingie i also bought
<libv>
over the last two weeks
<libv>
level shifter and serial to usb thing: broken.
<specing>
heh
<mnemoc>
ow
<libv>
actual cp21012 3.3V uart: works.
<mnemoc>
ah, now I remeber. you wanted to drill the black cover of your mele to get a DB9 serial port
<libv>
yeah, which i can forget now :)
<mnemoc>
:)
<libv>
at least the board is not broken :)
<libv>
so my worst fear didn't come true.
<mnemoc>
gut :)
<libv>
sadly though, i spend 6d a week at the customer now
nibb_ has quit [Read error: Connection reset by peer]
<libv>
and that probably will not change until september :(
<mnemoc>
:(
<mnemoc>
no summer vacations with your mele then?
<libv>
nope :(
<mnemoc>
:'(
<libv>
the original image on the thing has a noisy wifi driver
<mnemoc>
btw, do you know any good reference/sample to port the sunxi-disp dirvers to KMS?
<libv>
you probably want to look into rob clark's code
<libv>
everything else will be too big a mess
<mnemoc>
easy solution, build 3.4, wifi is broken there so it won't bother you :)
<libv>
hehe
<libv>
did it use to run at all with any kernel?
<libv>
any buildable kernel that is
<mnemoc>
wifi? yes
<mnemoc>
beware there are two drivers, the mainline rtlwifi one which neeeds a hack to be usable
<mnemoc>
and the allwinnerized noisy driver everyone uses
<mnemoc>
if you modify the usbc and usb_wifi section of your script.bin you can get the usb controller enabled since boot and then the mainline driver will take over
<mnemoc>
libv: "rob clark's code" means omap kms driver?
<libv>
right

<WarheadsSE>
mnemoc or anyone, familiar with any issues with the g2d driver?
nibb has joined #arm-netbook
<mnemoc>
WarheadsSE: i don't think anyone has ever tried it before
<mnemoc>
WarheadsSE: there is a directfb driver in the buildroot in the SDK hacked on top of vmware's driver
<WarheadsSE>
K, it just looks like it is often coming up, or instatiating when my boots shits.
<WarheadsSE>
Is that what the g2d is?
<WarheadsSE>
a hacked up graphics pit?
<mnemoc>
2d hw accelerator
<WarheadsSE>
mm
<WarheadsSE>
Havent tried *hard* to get that working
<WarheadsSE>
All the base systems seem to work fine
<WarheadsSE>
should have pictures of the A100 for you later
<mnemoc>
it would be great to make a exa driver using that 2d acceleration
<xenoxaos>
ya....but the micro/mini jack has 5 pins
<xenoxaos>
so you need to see if it's forcing OTG or not
<xenoxaos>
nm....if it shows up in lsusb, it should be good
<DonkeyHotei>
the cable has only 4 wires
<DonkeyHotei>
adb does not see it
<DonkeyHotei>
usb debugging is enabled
<xenoxaos>
any errors or anythnig in dmesg?
<DonkeyHotei>
dmesg on the laptop, or on the mele?
<rm>
WarheadsSE, mnemoc - so on a rebuilt kernel /dev/fb* appear instanly after "modprobe lcd"
<rm>
which i did not even have (=n) on previous iteration
<WarheadsSE>
heh
<WarheadsSE>
so my list *does help
<rm>
the problem was that lcd wasn't built
<xenoxaos>
good

[Sat 2012-07-21 02:20:37 PM PDT] <DonkeyHotei> so i finally got a usb device cable hooked up to the mele, but adb doesn't see it. what gives?
