Hi,

1) There’s no boot requirement for kernel JTAG debugging so as you like. 2) Well you need to attach before the crash happens. Some add a “while(true);” loop at the beginning of kernel initialization (after MMU enablement) so you have time to connect. Then you can step out of the loop with the JTAG. https://elinux.org/images/f/ff/JTAG_In_Linux_Driver_Debug_Anderson.pdf 3) Please have a look at segger and eclipse forums for app debugging: https://forum.segger.com/ https://www.eclipse.org/forums/index.php
