Cannot access Memory (@ 0xe000edf0, Read, Acc Size: 4 Byte)

c m

Hi guys,

I have been developing a LPC54616J512 (Cortex-M4) with a ULINKpro, however I changed some build settings and now I get the following message:

Cannot access Memory (@ 0xe000edf0, Read, Acc Size: 4 Byte)

I have reverted my code and build settings, but the message persists and I am still unable to connect to the device via SWD. I get the same error message whenever I try to erase the chip, so I can't recover the device.

The memory address the error message references (0xe000edf0) appears to be used by NVIC registers for Cortex-M4 Private Peripheral Bus (0xE000 0000 - 0xE00F FFFF) but I don't know how to proceed with this information.

Does anybody know I can recover the device?
