I am using a larger flash part, AT25QF128A, with MIMXRT1050_SFDP_QSPI.cfx.
I was originally using the LinkServer firmware on my LPC-Link 2 and I was able to debug and flash my custom IMXRT1050 board. Then I added some code to read/write from the flash while running in XIP and now I cannot debug the device at all with the LinkServer firmware.
Reconnected to existing LinkServer process.

People on the forums suggested switching to J-Link.
I've followed the instructions from BlackNight's blog. I also changed the MaxSize in JLinkDevices.xml to match the larger chip.

</Device> If I flash over USB, then run in debug, I am able to connect and step through the code. So that is an improvement over the LinkServer. But when I make changes to the code and try to flash/debug over the LPC-Link 2 within the IDE it does not work. It starts, does a compare, but never does an erase or program even though the code has changed.
Does anyone have any suggestions?
