I spoke with Brendon Slade and he recommended to open this case:
I'm writing because I have a problem in LPC811 during the Part id read through IPA (SWD) command, other IAP (erase and program) works fine.
This happens only with LPC811 (LPC811M001JDH16), i call the IAP, but the core doesn't halt.
in order i do:
-1- swd_connect return ok
-2- dap inits return ok
-3- read part id(see below) return error in dhcsr :the core doesn't halt
uint32_t command, result;
command = IAP_REPID_CMD;
can you help me?
