IDE: MCUXpresso IDE v11.0.0 [Build 2516] [2019-06-05]
Platform: MIMXRT1020-evk eval board
Example project: demos/iled_blinky
I'm experiencing a problem with a map file error in MCUXpresso when I put an ASSERT in the linker file.
If I have something like the following in the linker .ld file (this is just a pointless dummy assert):
ASSERT(__boot_hdr_start__ <= __boot_hdr_end__, "Dummy assert for map problem.");
I get an error from the .map generation:
Map file line:
0x00000001 ASSERT ((__boot_hdr_start__ <= __boot_hdr_end__), Dummy assert for map problem.)
Error:
no viable alternative at character '<'
The ASSERT works, because when I turn the expression to be >= the linker fails as expected. Otherwise it compiles/links fine. It is the map file that seems to have a problem. It is MCUXpresso that is reporting the error in the Problems tab. And I am unable to run the binary because of it (MCUXpresso IDE: Error: "Unable to perform operation: project build failed!").
I've used a completely fresh copy of the iled_blinky demo with just the ASSERT in the attached .ld file (which I created first as managed, and then edited and used it as unmanaged).
Linker command line:

Many thanks for any help.
