Stuffing Serial Bluetooth Module Inside C1k Casing
« Reply #90 on: September 09, 2005, 08:58:44 am »
not had a response from my contact, but he tends to spend a lot of time away, plus if he's got kids, he'll probably be having  a last minute holiday before schools restart.

so, in summary... all we need is the right bluetooth modules and to swap the flash and RAM chips in the 3100, replace the internal microdrive with a wireless lan adaptor, and we've got the ultimate PDA!

Just got news from CSR (Thanks, Miguel!) - There're no UART lines traced on DELL 350 module to either its connector or pads. So this module is NO good for using as a serial module. Sorry for bad news, folks...

any one know if there is a second usb port with tracks going somwhere we can solder ot, the pxa in those chips have 3 usb host ports and one client port (the client port can also reroute the signalks from one of the usb host ports to do usb OTG)

albertr, i need your help
It's seems that you know sharp's serial driver internal very well. After finishing all the soldering stuff i have a problem with software now. The problem is that when i run hciattach it initializing bt module and then after a second or bit less zaurus is fully, totaly , absolutely hangs. If i enable DEBUG stuff in the driver then it doesn't hangs but BT isn't working well.

Umm... weird. Is it in BCSP mode? Can you see if kernel spits out any error messages? I.e. configure syslog to log everything out to console, make your current vt a console and run attach command from this vt?

Yes it's in BCSP mode. I can't see any kernel error messages since it's hangs so completle that even fb driver isn't working. Some times it doesn't hangs and all working very good until i relaunch hciattach. And this is happening at any speed even at 38400.

By the way: i've tried your desharpised serial driver? but it seems that it isn't designed to work with an old pxa. It isn't receiving any characters.

If you didn't solder it to ffuart, how about running getty on ttyS0 and redirecting console output there?

The serial driver has some PXA270 dependencies, i.e. fifo size.

I've burned my ffuart so this isn't possible. I've changed FIFO size to 32 is there any other dependencies?

Ok i've got an OOPS with kernel panic "Aiee, killing interrupt handler! In interrupt handler - not syncing". I will check a backtrace.

Fifo size is defined in linux/include/asm-arm/arch-pxa/serial.h, make sure it's 32 bytes for PXA25X.

I think fifo thresholds might need to be adjusted as well, i.e.: check UART_FCR_TRIGGER_14 vs. UART_FCR_TRIGGER_8 where appropriate.

Errata #20 does not apply to PXA25X, so it needs to be undefined.

You may want to check conditional code (controlled by other defines) as well, since I didn't have PXA25X in mind, i.e. grep for "PXA" and "SHARP" defines.

What do you mean? How did i soldered it and where? I've soldered it to STUART. But STUART is sucks. Doesn't actualy working at speed > 38400.

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.
