I got the BlueZ...bad. Help...tumnus?
« on: February 28, 2004, 09:46:09 pm »
Using AmbiCom BT2000E (black, arched top), SL-5600 (PXA255, special kernel), and bluez-zaurus_2.3-2.4.18e-preempt_arm.ipk

# sdptool browse
Inquiring ...
Inquiry failed


The failure message appears immediately (ie it\'s not trying to discover and finding nothing).  Further investigation reveals:

# cardctl status
Socket 0:
  3.3V 16-bit PC Card
  function 0: [ready], [bat dead], [bat low]
Socket 1:
  no card
# cardctl ident
Socket 0:
  product info: \"AmbiCom,Inc\", \"BT2000E\", \"Bluetooth PC/CF Card\"
  manfid: 0x022d, 0x2000

        DOWN
        RX bytes:0 acl:0 sco:0 events:0 errors:0
        TX bytes:0 acl:0 sco:0 commands:0 errors:0


Finally, hciconfig hci0 up hangs forever...

Everything I\'ve read here suggests the BT2000E should be a drop-in-and-go card, and nothing cardctl or hciconfig tells me hints (to me, at least) why it refuses to initialise...

Help, please!

Try using the bluez ipks referenced in the BlueZ howto:
http://www.zaurususergroup.com/modules.php...ename=Bluetooth
I don\'t think the 2.3-2.4.18e version of the package is quite working properly.

OK, reverted to the bluez-zaurus_2.3-2.4.18d-preempt_arm.ipk package, but I\'m getting the very same output from all four commands, and hciconfig hci0 up still hangs.

What am I doing wrong?

Or, how soon will the no-PXA250-workaround non-preemptive kernel be available?  (I\'ll just keep trying new things until something works?)

Sigh.

Reverted to the stock Sharp kernel, installed the bluez-zaurus_2.3-2.4.18d_arm.ipk package, and service discovery works.  Kinda sucks being back at cache-workaround speed, though--especially with a PXA255.

When\'s that new special kernel hitting the street?

When a ZUG admin approves the download... I may have messed up some compatibility with those other modules somewhere (A BT card that refuses to be \'up\'ed is the symptom of this) and that\'s why I\'m going back to a fully compatible kernel.

So the PXA255s come with a kernel that has the PXA250 bug workaround turned on? That\'s stupid.

It would be interesting to see the Dhrystone output for someone\'s 5600 with a PXA255 CPU that has the ROM that it came with.

OK, technically this isn\'t the ROM it came with, since I reflashed it with a D/L of the 1.32 ROM from the Sharp website (to get rid of the \"special\" kernel), but the version it shipped with was 1.32, and these Dhrystone results are similar to those \"out of the box.\"

VAX MIPS rating =    195.116


I realise that 195 VAX MIPS is 22% better than the 160 I\'ve seen here on other threads with the PXA250 stock ROM, but I was getting 270+ with the \"special\" kernel, of which I can only attribute 71/400=18%=35 VAX MIPS to the 471 MHz overclock.  That would leave 40+ VAX MIPS to the credit of the pre-emptive patch, and I\'ve read your other threads where you described the pre-emptive gains as trivial, so I assume this kernel has the workaround turned on...

And BTW, tumnus, thank you for all the work you\'ve obviously put into the BlueZ package--this is a perfect example of the control, flexibility, and transparency I was hoping for when I ditched PPC for the Zaurus a couple weeks ago!
