warning: Couldn't determine a path for the index cache directory

[auftrag2021]

Hello, 

Hardware: MIMXRT1170EVK + RK055HDMIPI4M
SW: MCUXpressor IDE v11.3.0 [Build 5222]

When I try to upload a demo program, there is always this "warning" message.

C: nxp\MCUXpressoIDE_11.3.0_5222\ide\plugins\com.nxp.mcuxpresso.tools.win32_11.3.0.202008311133 oolsinrm-none-eabi-gdb.exe: warning: Couldn't determine a path for the index cache directory

Interesting is: it seemed, the program can be uploaded successfully anyway. 

Do I need some concern about this "warning message"? and Why?

This is a known issue with that version of GDB and can be ignored (if present, the index cache can improve debugging performance - but you are very unlikely to notice).
