gta01-pm-bt.ko is missing from modules

[bmidgley@…]

As documented in the wiki on ​http://wiki.openmoko.org/wiki/Bluetooth_Support
there is a module gta01-pm-bt that is required before the bluetooth adapter can
be used. It is not being built into the ramdisk.

I'm using a kernel and image dated 1 May 2007:

openmoko-devel-image-fic-gta01-20070501054014.rootfs.jffs2
uImage-2.6.21.1-moko10-r0_0_1883_0-fic-gta01.bin

sorry, I meant root filesystem above not ramdisk.

[laforge@…]

this is not a module, but built into the kernel. however, due to a mismatch of
platform devices and corresponding drivers, I believe the driver was not bound
to the actual device.

[bmidgley@…]

I probably should have mentioned this is a P1 device.

I look forward to doing some bluetooth hacking when you have a fix ready :)

[bmidgley@…]

even after

modprobe hci_usb

and

echo 1>/sys/bus/platform/devices/gta01-pm-bt.0/power_on

the bluetooth adapter does not appear using hciconfig -a

I've tried this on the latest dev image and on an image I built using
mokomakefile. Same result.

What hardware revision do you have? "P1 device" doesn't really make too much
sense, since P1 still has not started yet.

[bmidgley@…]

ok sorry I just assumed it was a p1 since it arrived very recently...

hardware gta01
revision 0240

[bmidgley@…]

for what it's worth, I have been able to get the bluetooth radio to work using a
recently built image. It shows up in lsusb and hciconfig.

I load hci_usb automatically and then manually power up the radio twice in a row
and then reset it. Even that doesn't always succeed, but at least with some luck
I can get the radio working and do some testing.

I suspect it's a fluke with this p0 phone.

[bmidgley@…]

I'm closing this ticket. The bluetooth radio will turn on and works consistently
if I power up and reset in a script so they happen one after the other. I
documented this in the wiki.
