As the newbie guide went to the topic of "I killed my simpad-what now?"
I started a new post.

the green light went to blinking after some charging.
I understand that I will flash the original simens OLD bootloader - using the jtag technic.
so I will go back to need to flash the new simens 2.5.3 -> to erash the flash, and then, need to flash the blupdater.img. right?

wouldn't it be simpler to just flash the blupdater.img?

Niv

Niv, a couple of us gave you the steps depending on which image you wanted to use.

If you are intending to try the old 0.8.0 or 0.8.1 images, you *will* need 2.5.3.

If you are simply flashing in the newer 0.9.0 or 0.9.1 images, you need to upload blupdater.img

I Mach so:

pin 1+2 bridge during I RESETS presses (in the back at the PAD)
>ich receives over serially the messages, which you gepostet.
pin 1+2 no more does not bridge, again RESETS!
>bl 2,4 bootet normally.

I agree with this. However I had forgotten this and put Familiar Opie 0.8.2 on top of blupdater.img and things seem ok. I think I remember reading that blupdater.img is not compatible with Win CE images, but I don't recall it being incompatible with Linux versions below 0.9.

That is mostly text. Save as a document or text file. You can word wrap if you have to.

Oops ... I stand corrected. Its more like, for newer >= 0.9.0 images, you *will* need blupdater.img and not the other way round. Also, with 2.5.3 Siemens bootloader, you will be able to flash back to wince images. Else, you need to revert to the simpadSL4.rom old bootloader before flashing in the siemens images.

You should try it so we can know if you can.

If you are at the point of jtagging, then you can pretty much fix whatever goes wrong with respect to flashing. Good luck.

I don't understand the guide: what pin should I solder to what?
I guess its pin 2 of J10 -> pins 2 and 4 at J12

niv · « **Reply #13 on:** August 30, 2005, 01:45:27 pm »

OK I soldered J10, and put a jumper to short it.
I used a cable that didnt have the GND lines connected.
I have now fixed it,and the cabe is as in the schem.
still, when I load Jtag and run the first command , It doesnt see the DLC5 cable.
I will look in to how the parralel port is defined in the bios, tomorrow.
Any help is welcome,
Niv

It's been a while since I jtagged my pad, so I can't remember exactly.
I believe, I didn't use /dev/parport because I hadn't parport support in the kernel. Instead I used
jtag> cable parallel 0x378 DLC5

How did you built your cable? It's important to keep it short and to have a GND line between each signal line.
