LPC55S66 rev.1 going to busfault on debugging

dingelen — Tue, 10 Sep 2019 13:40:28 GMT

Hi,

has anyone else experineced the LPC55S66 rev.1 on debugging with SWD going immediatly to a bus-fault, not entering the ResetISR?

Same code in a LPC55S69 does work correct. I've already tried several chips all with the same error, the LPC55S69 always works.

Versions IDE 11.0.1, SDK 2.6.2, Segger J-Link, using the standard empty project from SDK or the SDK examples.

Thanks,

Tom

Hello Tom,

Have you try to enter into ISP mode before trying to debug? In addition, please have in mind LPC55S66 has smaller flash and SRAM than LPC55S69. Is there any chance your application is consuming all the resources? Please check image below.

Best regards,

Felipe

Hi Felipe,

as you can see here https://community.nxp.com/message/1195953 it toke me quiet a time to get this data from NXP. It would be nice if you could verify this behaviour. It is happening with both examples from the LPC55S66 SDK2.6.2 as with own generated files. Running it on a LPC55S69 solves the problem.

Best regards,

Tom
