I have trouble with RPi-3 bare metal debugging. I use DSTREAM unit with DS-5 (upgraded, the latest version).
1. U-boot was added a startup code that sets up GPIO pins to support JTAG connection
2. DS-5 properly does boundary scanning, result is similar to https://community.arm.com/tools/f/discussions/5908/ds-5-and-raspberry-pi-2. CPUs are properly detected, no error is reported. Startup code does the job, as without it the boundary scan fails.
3. When I try to connect to the target, I get this error message:
Unable to connect to device Cortex-A53_0
An unknown error was received.
DS-5 documentation says it support RPi-3. What do I miss?
Thank you for your help,
Jarek.
