I was just wondering if you overcame that kernel panic problem you had.  Well, congrats on your 128MB C700 revival!

I've just received my renewed C700 from Maslovsky  Not it has a new PXA255 CPU and 128 MB RAM onboard. I will try to solder BT module to FFUART again.
[div align=\"right\"][a href=\"index.php?act=findpost&pid=96045\"][{POST_SNAPBACK}][/a][/div]

Is that 128 RAM, or storage space?  Is there a thread somewhere describing/discussing the process?

Cheers!

Anton,

Are you talking about your c860 or c1k? If you guys find a way to trace btuart lines on c1k's pcb, please let me know. I'm not ready to lose my ffuart yet, still need it for serial communications. Also, if anyone would be brave enough to desolder pxa270 from C1k/c3K/c3.1K pcb, I'd like to see hi-res pictures.

I just made a small workaround. But the problem is still exists. When HCI layer is calling serial driver write function this sometime couses bcsp layer's pointers corruption.

Interesting... I'm using Affix and bcsp support seems to be ok there.

The problem isn't in bluez, i think. It's seems that the sharp's serial driver couses some memory corruption.

128 MB of RAM.

i am also intrested in high res photos of any of the c3x00 or c1k, i am sure i saw one where they removed the chip (or was that a c700). the pxa270 also has a bluetooth serial port that can go up to just under 1Mb/s, i also belive it had a 64 byte buffer instead of the 32 byte one but i cant find any info in the pdf's to prove/disprove this

It's still my C760 with a black keyboard from a C700 and black screen from C750 with 128 Mb or RAM and soon-to-have bluilt-in bluetooth

And we have plans to solder 128 Mb of RAM to my C1000 too...

I have success with an adaptation of the Albert's serial driver to run on PXA25X. Bluetooth is seems to be rock stable now.

You may already have seen the [a href=\"https://www.oesf.org/forums/index.php?showtopic=15043]photos[/url] I published in this forum topic.  Let me know if you need more detail.  I can magnify and crop any specific chip or section of the C3k motherboard I took pictures of.  Cowardly, I did not desolder any of the chips from the board.

2x4ever,

If you have any patches or suggestgions, that would be great! Did you test this driver with irda and apm suspend/resume? I didn't have much time to test it, so any help is appreciated. I hope to find some time to revisit it soon.

Any news on your modifications? Am still champing at the bit. I am still thinking that a C3100 with the C1000 firmware and an internal CF bluetooth adaptor would be the coward's way out!

I haven't seen/heard that anyone is using  an internal CF slot of C3.1K for anything other than CF/IDE cards. My quess would be that it won't work for serial UART CF cards, like bluetooth cards, at worst,  or would require to write a custom driver, at best.

Why not?  The C3100 kernel supports 2nd CF slot as well as pcmcia scripts do. I think any CF card will work just fine.  I would have tried that myself but I don't have a C3100 to play with...
