[Bluez-users] Can't open device hci0. No such device(19)

[Daniel Haensse]

Hi list,

On the embedded platform when I call hciattach, it generates some error, on 
which I need a hint now to search the bug.

I'm working on a bluez port for uclinux running on the dragonix platform which
uses a 68vz328 uP.I did cross compile the latest bluez kernel and userland stuff
for the 2.4.20 kernel and did substitute fork with vfork in hcid for support of 
uclinux.

On my SuSE 8.2 box (pretty outdated bluez sources), I have the bluetooth
modules running without any problem (attached on ttyS0), however the 
embedded modules are a newer version with larger flash memory (class1, Mitsumi  
WML-C20, CSR chipset on UART).

Find attached the error log, with debug enabled in the kernel net tree.
What is this timeout  OCF_WRITE_PG_TIMEOUT? Sometimes I also get a
OCF_WRITE_CA_TIMEOUT succeseful. Might this be related to our "slow" cpu 
(68vz328)?

Could anybody please point out where to start?

regards

Dani
