LPC 1768 CRP3 Enabled Device Recover

[vijayg]

Hi,

We are using LPC1768 with CRP3 is enabled in the code for security purpose.

But due to some FOTA issue our Application is got corrupted and not running.

We want to recover this Device's either JTAG or ISP Mode.

Since CRP3 is enabled , LPC1768 not allowing JTAG and ISP Mode.

Please any suggestion to Recover those Device's.

Hello @vijayg 

I don’t believe the device can be recovered because, at the CRP3 level, both ISP  pin and SWD  are disabled.

Be aware that there is no built-in recovery for designs once CRP Level 3 is enabled. The most simplistic way of implementing a custom recovery mechanism involves the “Re-Invoke ISP” IAP call.
