Hi,

when I wrote a TPU function I also didn´t get the debugging mode 
running. I used a very slow TPU clock and monitored the parameter RAM 
of the TPU with my own software. So I could see, what was going on. 
Some internal states were stored in dedicated bits of the parameter 
RAM and I was able to follow the internal stages of my TPU software. 
It is also possible to use extra bits, just to show the CPU were the 
TPU is working.
In my application (IIC-Bus) this approach worked quite fast, so that I 
never had to understand why this debugging mode of the TPU does not 
work.

Best regards
