own cap 100% CPU?

Hello!

I build an own cap with Inputs, outputs (relay) and Rs232.
When I put the cape on the BBB, the power LED is on, and also the CPU and Heartbeat LED is on and keep on.
Seems the BBB CPU is on 100%?

Is it possible to setup a log while booting?

A debug serial FTTI cable I doesn´t have right now.

Thank you!

Sounds more like you may be creating an interrupt and have no SW to answer it. You really need to get the serial cable o see what is going on.

Gerald

Thank you!

Serial cable I order today. Need to wait now.

Hello!

Now I have the debug cable.
Here is a boot without my cap. Power from USB:

There seems a lot of wrong? First line beginn with unnormal Chars.
And continue until he load my own CAP. Then a lot of errors.

I order Solderless Flexible Breadboard Jumper Cable Wires. Then I can connect Pin by Pin and always boot betweem and checkl with I/O are made the trouble.

But maybe someone see the error in the debug log?
