Hi,
I often use a simple bit-bang function at some high buad rate and one
gpio pin. I hook a serial terminal to it. Depending on CPU speed, etc.
interrupts may have to be disabled during the time the character is
actually being sent. One character at 115,200 is 0.1ms so unless the CPU
is very

You won't see anything from preinit with set -x because when preinit is

Thanks to everyone for the great suggestions!
Since I'm new at going this deep into shell debugging (and almost
never on a embedded target) I'll have to check out each of these
suggestions as I've never heard of some of them.
Is it possible to start preinit with -x and redirect the output to the

Ah, I didn't think of that!
I didn't think about running wireshark to capture the script output
... I'll have to look into that. I'm well versed in wireshark.

I've never needed to really get into the startup scripts much but now
I need to try and understand how the mini_fo union gets set up so I'm
trying to learn the startup scripts like preinit.
When I ad to fiddle with this part of the code, I'd add some
echo blabla /tmp/mydebug
in those

Another option might be to send that debug output to the network as is
done in preinit_net_echo and read it via tcpdump.
You can also use socat to receive the udp broadcasts without exiting
