LPC17xx - Cannot halt process issue

software3 — Tue, 27 Aug 2019 13:45:28 GMT

Hello everybody,

I'm stuck with a "Cannot halt process" issue while trying to program a LPC17xx MCU on a custom board. I've loaded in debug mode several time the same project without any problem, but at a certain point it stopped working and I can't program che chip anymore. I've tried to follow the instructions about Regaining debug access to target MCU , but unfortunately I still can't access the chip in any mode.

I've also tried to erase the Flash memory from "Debug configuration" window, but it gave me back the same error.

This are the console messages when I launch the debug:

Cannot halt processor
Failed on chip setup: Ep(04). Cannot halt processor.

I'm pretty sure that the loaded project didn't block access to Flash memory in any way.

What can I do to program the MCU again?

Thanks in advance, best regards.

Hello Marco,

What happens when you try to boot into ISP mode? Does it enters successfully into ISP mode?

Best regards,

Felipe
