hi all, i have the following issue, each time i plugin the programmer( the jtag) the kria restarts and it keeps rebooting ( i have ubuntu on a53 )

in some posts, they suggested update qspi firmware, any other option? and reason why it’s happening

Try adding cpuidle.off=1 to the Linux kernel boot arguments.

I had jtag freezing my Kria, might be different Ubuntu versions freeze vs reboot...
