LPC811 debug "No source available" error.

Trying to use LPCXpresso v8.1.4 to program an LPC811 via LPC-Link probe v1.3.

Results in "No source available for "0x1fff0008" error message.

Reading the UM, the 0x1fff0000 memory space is related to the bootloader mode.
Researching, I found a past forum post that suggested this sort of issue may stem from the processor being in ISP mode.
According to the UM, ISP entry pin can be either PIO0_1 or PIO0_12 (depending on the marking and bootloader version, neither or which do I know how to verify).
The specific name of the processor that I am using is LPC811M001JDH16, which, according to a different section of the UM, uses ISP entry pin PIO0_12 (physical pin 2).
I added an external pull-up resistor to VDD on this pin to avoid ISP entry.

PIO0_1 in my application is tied to an external, 24MHz clock signal.


I'm at a loss for where to look next.
Does anyone have thoughts on this issue?
