l2ping from either end works. I didn't cross-compile hcidump for the ColdFire
board, need to do some makefile wizardry in the parser subdir first. l2test
on both ends just sits there waiting for something, no doubt I'm not invoking
it properly. hcidump on the pc end shows the ping packets arriving from
ColdFire. I guess my connection is basically working. On the ColdFire
board:
/bin> hciconfig
hci0: Type: UART
BD Address: 00:0A:4F:00:13:5F ACL MTU: 192:8 SCO MTU: 64:8
UP RUNNING PSCAN ISCAN
RX bytes:289 acl:0 sco:0 events:14 errors:0
TX bytes:554 acl:0 sco:0 commands:14 errors:0

But invoking hcitool still yields:
/bin> hcitool info 00:0A:4F:00:09:5E
Requesting information ...
bcsp_timed_event: Timeout, retransmitting 1 pkts
Can't create connection: Input/output error
pid 54: failed 256

bcsp_timed_event: is a kernel error msg. I should probably try to set up an
l2test session properly next. Any advice?

Thanks,
