Other Parts Discussed in Thread: CC2564
We have connected the UART/power supply of the evaluation board CC2564MODAEM with a starter kit (i.MX6 ULL).
To perform a first functional test, we followed the example of TI at https://processors.wiki.ti.com/index.php/CC256x_Testing_Guide#UART_Communication Currently we get a valid response frame but immediately after that a "Hardware Error Event" follows and then no more communication is possible.
Fuctional test:
With the following command sequence the module responds after a manually generated shutdown as follows

But there is a second event which reports a hardware error. Afterwards the Bluetooth module does not answer anymore.

The hardware event is described in the TI forum, but there is no answer there.
@Ti
What are the causes for Hardware error event?
