I don't have IAR here. I will check monday. My options for reset are
"normal" and "reset all peripherals" If I can't see what it runs I will
ask my contact at IAR. At the price I pay I should be able to get a
clear answer. I spent several days trying to figure out why it was not
programming correctly.

I only found the problem in code where I use DMA. I haven't tested
OpenOCD with IAR, I use the yellow device from Segger and the IAR driver.
