Hi Community,

What are the differences in the startup behavior between ED and TP devices?
Our TC37x ED devices startup without a debugger connected in standalone mode without problems.
Our TC37x TP devices do NOT startup without a debugger connected in standalone mode.

Thanks & Regards

I think is a matter or the starting address saved into the BMH

Thanks, this was exactly the point. I needed to change the UCB.
In the ED device the BMHD was automatically set, but not in the TP device.
Is this a normal behavior in TC3xx devices?
In TC2xx devices I didn't need to change the BMHD manually, because it was read via HWCFG pins.
Also the Start Address was pre-configured to a default value in the ED device.

Hello,

By default, the BMHD doesn't have a default STADD set. User shall configure it during flashing as per the requirement. Please configure the BMHD data in the SW as per your requirement with proper CRC, CRC Inverted and Confirmation code.

You may refer to the below code example (of Blinking LED) for more details on how it can be done in the SW.

Prudhvi.
