Could you provide your u-boot environment? printenv

Does this processor reset happen when the DSP program isn't automatically loaded? Does it happen if you try to load a simple hello world dsp program?

Does this processor reset happen when the DSP program isn't automatically loaded?

No.

Does it happen if you try to load a simple hello world dsp program?

No, with simple hello world dsp program working fine.

Jonathan,
with simple hello world dsp program following is:

That is very strange. Could you comment out pieces of your code until it starts working again? To see if you can determine a section of the code that causes this and we can look at it to see if we can determine what is going wrong.

Jonathan,
Could be my problem connected with to the that there is no pull-up on SPI1 on the own carrier board?

Thanks

Looking at our devkit, we don't put any pull-ups on the spi1 pins. https://support.criticallink.com/redmine/attachments/download/15416/80-000268RI-3_SCH_RevC.PDF

Thank Jonathan,

The problem is resolved. The problem was in hardware.
