nic_slogf not working with io-net
Hi,
I am trying to write an SCC ethernet driver for my 800fads.
I am facing a problem using nic_slogf.
mount hangs wen i try to mount the driver, but wen i comment out nic_slogf, the driver gets mounted.
mount process is in RECIEVE bloked state.
But if i use nic_slogf in a seperate application program, its working.
I am using nic_slogf in the init function of the dll entry.
Please help. Below is a snippet of the function and state of io-net.
Thanks,
Jayanth
</snip>
int init_scc_eth(void *dll_hdl, dispatch_t *dpp, io_net_self_t *ion_ptr, char *options)
{
//setbuf(stdout, NULL);
nic_slogf( _SLOGC_NETWORK, _SLOG_ERROR, "Hello World 1\n");
if ( (pv_immr_base_addr = mmap_device_io(32*1024, (get_spr(PPC800_SPR_IMMR)&PPC800_IMMR_ISB_MASK))) == NULL ) {
errno=EIO;
return -1;
}
...

Re: nic_slogf not working with io-net
Yes I have slogger running.
If i log messages through an application program independent of io-net, its
working perfectly.
(Ran the application, confirmed the messages logged.. then mounted the
driver which fails)
Here is how I am mounting my driver...
#io-net &
#mount -T io-net /proc/boot/devn-temp.so
(system hangs if nic_logf is used in the driver entry)...

Re: nic_slogf not working with io-net
The pidin shows that thread 3 tried to lock the
same mutex twice. Attach to io-net with the
debugger and get a backtrace of thread 3. The
slogf probably just changes the timing and has
nothing to do with the root cause.

Re: nic_slogf not working with io-net
Hi Sean,
I need a little help in attaching the debugger.
My board is connected to the host only through one serial cable which I use
for console terminal.
Can we attach a debugger through the same serial connection? coz my setup
does not yet
have an ethernet driver.. yet.
If yes, can you tell me how to or point me to the link with instructions?
Thanks,
Jayanth

If all you want is a backtrace, do this:
# dumper -p <pid_of_io-net> -d /tmp
which will snapshot a core file of io-net
which you can then look at with gdb.
