The XSCT breakpoint add command (bpadd) has been enhanced to enable cross triggering between different components.

For example, use the following command to set a cross trigger to stop Zynq core 1 when core 0 stops.

bpadd -ct-input 0 -ct-output 8

For Zynq, -ct-input 0 refers to CTI CPU0 TrigIn0 (trigger input 0 of the CTI connected to CPU0), which is connected to DBGACK (asserted when the core is halted). -ct-output 8 refers to CTI CPU1 TrigOut0, which is connected to CPU debug request (asserting this pin halts the core). hw_server uses an available channel to set up a cross trigger path between these pins. When core 0 is halted, the event is broadcast to core 1 over the selected channel, causing core 1 to halt.

Use the following command for the Zynq UltraScale+ MPSoC to halt the A53 core 1 when A53 core 0 stops.

bpadd -ct-input 16 -ct-output 24
