Hello Ulises,
My apologies for the delay.
I saw that you posted another thread regarding the demo for the i.MXRT1170 EVK. Is the problem still present or where you able to solve it?
I couldn’t find a clear answer on what could be the issue but the preprocessor error “macro names must be identifiers” would appear sometimes when there are directives to see if a symbol is defined but it should not start with a digit. However, from what I understand you are nor making changes to the sources themselves.
If the problem is still present, have you made some progress or is there any change on the error log?
Regards,
Gustavo
