Thanks for your updated information.
Another point in your MCUXPresso 11.1.2, please also try set the SDK debug console to UART console instead of Semihost console, any updated result?
Best Regards,
Kerry

FlexRAM contains: OCARM, ITCM, DTCM, and share 128KB flash.
So, when you want to change it:
1. modify the memory map size
Change the OCRAM, ITCM, DTCM size in the following picture
2. Modify the flexRAM code in the reset :
Take an example, you need to check the register and modify it for your own size:
FLEXRAM->TCM_CTRL = 4;
IOMUXC_GPR->GPR17 = 0x5AAFFAA5;
IOMUXC_GPR->GPR16 |= 0x7;
IOMUXC_GPR->GPR14 = (9<<20) | (8<<16) ;
3. modify the .scp for your own memory size
You can find the .scp in folder:
C:\nxp\MCUXpressoIDE_11.1.0_3209\ide\binaries\Scripts
an exmaples for your, you still need to modify the related data

From your picture, that your project occupy too much OCRAM, your OCRAM is overflowed.
Do you put your code in the RAM, not the external flash?
Please check your code, seems your side a lot of code is put in the OCRAM area.

OCRAM in default is 64KB, your code should already overflow it.
You may try to define some larger RAM code to the ITCM or DTCM.
Or you can enlarge the OCRAM size to 128KB, and disable the DTCM and the ITCM.
More details about the flexRAM modification, you can refer to the application note:

Here for example is the memory map from the evkmimxrt1010dev_audio_speaker_bm example. We can see that in this example it allow more OCM than TCM but its still not enough to use the fatfs and codec in the same code. How do i arrage this map in order to get enough on chip ram for my project.
