I'm using a MIMXRT1010-EVK dev board. I have managed to corrupt the OpenSDA debugger that resides on the LPC4322JET100 chip. After some experimentation I have managed to reprogram the boot loader with a bin found here
MIMXRT1060-EVK as this seemed to be the closes to what I need.
When I connect the debugger it now shows as RT1060-EVK. I was then able to get it into MAINTENANCE mode (which incidentally required the changing of jumper J27 on my board, not in the documentation and why I got into this problem). From MAINTENANCE mode I was then able to reload the DAPLink v0244 firmware, again for the RT1060. My Eclipse IDE can now see the debugger, however this is the result of a debug session:

Not totally unexpected. So my question. Is there a copy of the boot loader and DAPLink binaries for the MIMXRT1010-EVK available?
