Content originally posted in LPCWare by sgoadhouse on Tue Jul 01 08:10:29 MST 2014 I have been working with the LPCXpresso IDE (7.2.0) and the Embedded Artists LPC4088 Quick Start Board. I have run into an issue which results in the code dropping into the Hard Fault exception. Instruction Trace, which is technically possible with the LPC4088, would easily help locate the issue. However, the LPCXpresso IDE appears to only support the following targets at the moment:
Content originally posted in LPCWare by lpcxpresso-support on Tue Jul 01 10:15:17 MST 2014 Instruction trace on M3/M4 parts with LPCXpresso requires the MCU to implement both ETM and ETB blocks. Unfortunately LPC4088 does not implement ETB and there are no plans to support ETM only instruction trace within LPCXpresso. You can obtain third party tools and debug probes (e.g. Keil) that will do this though.
