[Cryptech Tech] uwTick and debugging

[Michael Dockter]

solved. To fully initialize a debug session you must use the gdb command "monitor reset halt". At one point the Eclipse IDE must have been generating this (and other commands) automically and I must have deleted it or configure my project somehow to mess it up...


(gdb) monitor reset halt

target halted due to debug-request, current mode: Thread

(gdb) break main
Breakpoint 1 at 0x802059c: file hsm.c, line 455.
(gdb) continue
Continuing.
Note: automatically using hardware breakpoints for read-only addresses.

Update. With yet another alpha/releng install and build from the toplevel Makefile produces a hsm.elf that runs as expected when flashed and run from reset, but hangs at the same point during debug. For now I'm going to take this clean copy and merge in my code using the burn and learn method of debug.

Wrong layer for me, you want Paul or Fredrik. :)
