found a way to use the usb output for a tv-out

According banxian Meizu says that adding tv out on m8se is possible under 10 $ so there must be a tv out somewhere, problem is where.
If someone could figure it out it is just a need for drivers.

or to connect a external drive

s3c6410 supports usb otg to do this, but when i contacted meizu in the past they denied that m8 had this, so i am not sure, maybe the normal usb port can be activated in this state to do this.

or a keyboard or anything else?

well i thought i saw some guys that were building drivers for Bluetooth keyboard/mouse sets to run on android, so this could be an option once BT works or one might make a mod like for Iphone: a keyboard, somekind of arduino to convert inputs from keyboard to serial debug port to provide the input...

(if you would take the VGA output/keyb/mouse/hard disk : M8 could be a great computersystem!! Even broken M8 due TS problems could be usefull again)

I will wait for my ttl converter but im more and more concerned if i had destroyed the serial port already...

I hope the serial is not fucked up. Future will tell...
but if it can give you any comfort, i fucked up my ttl also this weekend by soldering new wires to it:s i hope i can restore it other wise i am going to buy a new one (model like Loonix got? much easier since there is no need for soldering)

evow,bill,banxian or any other with a jtag:
Could some please try to dump the first
80MB

love to do it but my m8 i still on his way for replacement GRRRRRRRR!
sorry

ps i would dump the complete NAND , in case anyone screws it in the future..

edit about keyboard ideas:
Iphone:

link 2


Android:

In Android kernel there is a usb otg driver included and loads succesfull.
SMDK6410 Board has a HW otg port (one of 4 or 2 usb ports) if this is the one that goes out, i can see so problem.
BTW i think you could connect any usb hid device if you had a driver for it, so keyboards cams gamepady harddisks etc. but the future will show if we can get it to work

Thats good news!
but does not mean that there is an actual in/ouput.
anyone has an idea how to test this? Think it should be possible on the terminal but no idea how :P

If usb On-The-Go does not work, it could maybe be done with the normal usb to peripheral driver, but i am not sure about it :s
Drivers will be needed indeed, but first we should see debug output on the physical layer before doing a big job for nothing.

Btw R3wdy, anyone answered allready on the jtag request?
and do you have your jtag reader allready?
if not maybe you could load the upgrade system with your current kernel?

No one but you concernces my problems
Till today no jtag reader came, but i looked on the sjf code and there is a read function. With a little modification i think it can do a dump to disk. so i could write it back. This i will try when i get my jtag

i thought about the linux idea. I would need to copy the binary to ram and execute it there. But the linux kernel will not let me execute any code.
For this i need to ask linux experts.
The second thing i thought was dding from the mtd device so anyone could dump it for me, but this (reading or writing) mtdblock4 gives kernel exceptions. So no way i think. I cant exchange the kernel without upgrade system so i cant try other driver or so

P.S. ist a small r in r3wDy :P

No r3wDy!
I think nearly every one here hopes you will get your phone back to work!
You give so much good Advice it would realy be a shame if you should not profit from it yourself.
One of us will manage to dump the full Flash memory and then you will get your M8 back.
Please dont give up!

I just cant give any helpful advice thats why i dont try to 'rub it in'

BTW, is there any way to identify the JTAG contacts without a real JTAG reader?

If evow04 lives close enough to me ( ghent) , he could borrow my m8 to do the jtag readout ?

w have the jtag pinout already. I have just soldred a new ttl conerter now i will see if the serial of my phone still worx

sorry bad habbit

need to ask linux experts

why dont you try the guys from the mer project? they seem to be very willing to provide help?

i looked on the sjf code

beeing honest i would use openocd or how was it called, cause there is a support and community after it, they could provide us with info when needed?

way to identify the JTAG contacts without a real JTAG reader

Loonix, we have the m8 pinout, so there is no need anymore to identify the pinout, but i think you mean for M8SE cause if i remember well you have the SE?

We should urgently need the pinout for SE aswell, maybe Bill might have it?
Or we could try an other way:
if someone with normal m8 could measure the voltage for each jtag pinout that is known for M8, maybe they could provide us with clou´s to find pinout on SE? Since serial is 100 pct swapable between both models it might be the same for jtag..?

just soldred a new ttl conerter now

thumbs up!
btw since no one will be wanting to solder on m8, could you r3wdy try to make a schematic like i mentioned in the jtag topic? This to be used with pogopins?

close enough to me ( ghent)

cool! Ghent is not that far but hey nothing is in belgium cause it is that small.
Only problem is that i am pretty sure my jtag cable is dead and the only parallel port i have is on my 386 pc with win 3.11 lol
So reading out will be possible but how the hell will i be transfering file(s) from it to my other pc´s :P

I was waiting on buying a new jtag when i am sure my replacement gets shipped, with some luck it will be in stock in 4 days and 1-2 weeks later i could have mine back.

Think i will wait just a few more days and order a cable straight away.
edit; does anyone know if android/linux drivers are interchange-able?

im just to fucking dump to solder i think

I soldred the ttl coverter (btw this one DIGITAL CONVERTER KIT CMOS/TTL TO RS232, 3V, LOW POWER bei eBay.de: Sonstige (endet 03.11.09 20:35:58 MEZ))
gave it 3v and gnd from m8 bridged tx/rx with a cable and got nothon back in terminal... i think the character i type should come right back to terminal right???

r3wdy,
thing you could do first:
*shorten tx with rx on the serial ttl. (so do not connect to m8 just yet)
*launch HT/tt/dnw/..what ever..
*select the com port you use with the needed connection speed for m8
*input any keys.. it should immediatly return onscreen..

if not something is wrong with the ttl or ht/tt/ or other.
If it works:
*connect ttl rx with m8 tx & ttl tx with m8 rx & ground
(leave 3.3 volt vcc wire disconnected for now.)
*enable the terminal
*boot M8 and pray for output!

ps: researching jtag again, will update in jtag topic

*shorten tx with rx on the serial ttl. (so do not connect to m8 just yet)
*launch HT/tt/dnw/..what ever..
*select the com port you use with the needed connection speed for m8
*input any keys.. it should immediatly return onscreen..

tried this, but with gnd/3v from m8 to power max232. nothing came back... gmrl. i shortend rx/tx dirct on the cable -> came back ro i think its a problem with power/connection on the ttl conv. board. i will see that later i go running now

i go running now

enjoy!

interesting:
Open OCD guide

i shortend rx/tx dirct on the cable -> came back

so the ttl works!

gnd/3v from m8 to power max232. nothing came back

Did you try without vcc wire?

@r3wDy:
I leave 3v no conencted because my converter get power supply from PC side.

@evow04:
If you want to connect usb keyboard to M8 I think a boost module is used for get 3v to 5v, or keyboard have battery in itself.

@banxian: what are you doing for android right now? (i am pretty curious!)

first: inject loader and kernel into Meizu xip, type A / C though serial to jump Android / WinCE in 2 seconds hint. progress: inprogress.

second: write ROM cooking how to, and put patched aesop/bill version kernel / busybox rootchanger to gitorious and source forge, this makes other guys can easily and safety join our cooking. progress: preparing.

last: write bare screen touch detection n button detection in TinyLoader, when these function worked, try to write bare nand reader to separate kernel from MeizuOS. this makes people can update kernel / image / patched MeizuOS with bootloader separatly. because MeizuOS (stock firmware) only update in one or two mounth delay now. progress: finding method

dunno why ttl doenst work, will see tomorrow.
and i dont get jtag to work, sj tool doesent detect cpu, but i will try on another computer. And i need to think about how to connect cable to m8. i think my method is not not the best...

but all in all i think if not a miracle happens i will never get it to work again, just nothing works like expected this sux like hell

send it back 2 meizu ? =/

i'm sorry for you r3wdy... if i could do something, i would do it

@banxian: nice to see a progress the first thing you mentioned would be the dualboot or somethin else?

i can't wait for the howto, every morning, the first thing i do is, to check if you have written the howto

raoul

Banxian,
for touchscreen selection:
i would just go for the volume up/down + M key for the os selector,
It will save you problems and time.
I near future we could have a look onto TS if needed? (think loading ts will slow down boot)

About the dualboot, can busybox load wince also?
I would not make it difficult to make this happening:
partition movinand :
*500 Mib=> wince xip + settings (fat32)
*500 Mib=> android xip + settings(ext3)
*7~15Gib for userdata like mp3´s,movie´s ..
Let the tinyloader mount the xip.bin´s from there, it might slow down the boot proces while copying into ram but it will make upgrading the firmware more easy, just hook on to usb mode overwrite the belonging xip.bin, restart and done. (save lots of work and trouble from the upgrade menu)
And another way is looking at the uboot option since this can load ce + *nix, it is just a matther of compiling drivers into it and a selection menu?

dunno why ttl doenst work

didn´t you make a new usb cable?
if so, hook it (usb cable) onto m8 take the multimeter and check the voltages coming from m8, to make sure it is not a wiring issue.
Seems that you have a really annoying problem!

dont get jtag to work

Got your jtag reader?
If it does not run, try to look @openocd software and keep in mind that since you ordered a parallel cable it could be very slow in function.
I saw somewhere that openocd had a patch for the s3c6410..

i need to think about how to connect cable to m8

if you mean for jtag pins, take a look in the jtag topic, i posted a very clever and easy way to secure the connection between jtag cable and pinout by using some plexi in the form of the battery...
(shame still no one answered on to it!!!)

send it back 2 meizu ? =/

do not think it is an immediate option, cause the chance it will be replaced under warranty is small...

@Loonix, you still out there? if so, received your TTL allready?

@evow04:
If you want to connect usb keyboard to M8 I think a boost module

yes indeed that idea crossed my mind, but i must say that i am more interested in a BT wireless keyboard. So i am awaiting to get started with that once i have m8 back.

I am still here and still waiting for my TTL
shipping from china, exactly like the 10 pin mini USB connectors i ordered
but at least those eBay orders are already shipped in contrast to the Screen guard i ordered from another online shop -.-

I will grab my Multimeter again and try to find some useful values for the SE later.
