question for Ziann123 – I have Jtag connectors or at least I think I do. It shows pad with GND, TX, Rx, 3v3. Do you picture of your connector you used to connect to the jtag connector? should the device have power or does the power come from the Jtag?

Hi Francis,

I wouldn’t pay $45 for a brand new M001, let alone for parts! The market has moved on a lot in the last 12 months.

You might be able to find someone whose M001 has died in a different way and get a touchscreen more simply, though. Good luck!

Thanks for this. I just hooked up my broken M001 (smashed touch screen, broken lcd) fire up Putty and up come the linux boot messages. Command line fun! Now all I have to do is to work out whether it’s worth forking out $45 for replacement parts. To tell the truth the M001 aint very good – horrible, horrible 256 colour(in 2011) LCD and laughable battery life. ( But I do like the guess at what the ipad was going to look like – attractive if not very functional). The M009s is thankfully much better.

It looks like Im closer to a working unit BWO the SPI method…
Still cannot get a response from the JTAG connector, but only a couple days away from the SPI fix…

Will drop by again to say ‘yay or nay’!

Hello again!

I found out later that the ‘soft brick’ (what I call it now) DOES in fact have JTAG pads on it, and I (supposedly) connected to it with a BLACKCAT-USB unit…

Does not do much more than questioning if the device has power.
As the BC is also setup to program SPI directly I have ordered the chip adapter and wait for its arrival. I have already removed the SPI from the ‘hard brick’ (different device. same chip) and intend to ‘practice’ on it before swapping out the chip into the ‘soft brick’…

But I DO have a Sylvania board (more like the ‘hard brick’ in design) that works!

@hoppo Not trying to act the Martinet or anything here, but you don’t solder the Nokia CA42 USB to LVTTL serial port adapter to your JTAG pads. JTAG sigals are stuff like TCLK, TDI, TDO, TMS etc.(on the CPU card of my (Maylong?) ‘Pad.)
whereas our serial console port has good ol’ TXD RXD power gnd.
(that’s in ‘The Dongle Box’ for my ‘Pad, thought I didn’t have one for a minute there)
BTW 115000 baud no flo control for serial console.
if it stays ‘dead looking’ then it’s JTAG time.

Thasso,

It’s a serial port, with some caveats:

First, it’s just a LVTTL (3.3v) serial port not an RS-232 serial port. Different signal voltage levels.

Second, Linux kernel console is running on that serial port so AFAIK you’d need to change the console= boot parameter to put the console somewhere else, before you could use it.

Another 3.3v serial port (ttyS1) is apparently available on the dock connector. I don’t know the details, but you might want to try and find out about that one (although USB is also available on the dock connector, and internally, you could always hook up a USB GPS device or a USB< ->Serial adapter with a GPS device.)

Hello there,
great Work!!!!

I have one simple question: is the serial Port, which you have used, a real serial port? For example: Can i solder a GPS Mouse with a serial cable (RX TX etc.) directly to the Pins and select this Port in any software? The great benefit would be that there is no need for drivers when the navigation software talks directly to the GPS receiver via Serial port and gets it datas via RX TX…
Please gimme a answer…
