I have implemented a latch for checking resetrequest. The CPU always starts after resetrequest is released, when i do the following:

Step1: assert resetrequest

Step2: wait for a rising edge on resettaken

Step3: download hex

Step4: deassert resetrequest

but if i do not download the hex-file (Step 3) the CPU does not start again.

Thats why i thougt, that i have to do something with the RAM (Stack reset or smthg.) before releasing resetrequest.
