  17 # On CC32xx family of devices, sysreqreset is disabled, and vectreset is
  18 # blocked by the boot loader (stops in a while(1) statement). srst reset can
  19 # leave the target in a state that prevents debug. The following uses the
  20 # soft_reset_halt command to reset and halt the target. Then the PC and stack
  21 # are initialized from internal flash. This allows for a more reliable reset,
  22 # but with two caveats: it only works for the SF variant that has internal
  23 # flash, and it only resets the CPU and not any peripherals.
