imxrt build error, `SRAM_DTC_cm7' overflowed

[sukyeong]

I modified the code a little, but suddenly I get a build error.

Is there a problem with the settings?

I've tried to find a solution to the problem, but I'm not sure..

error message is 

`.bss' will not fit in region `SRAM_DTC_cm7'

region `SRAM_DTC_cm7' overflowed by 162336 bytes

Hi @sukyeong ,

   Your result demonstrate your project DTCM is not enough to use.

    To this situation, you can put some data in the ITCM, don't just use the DTCM, your ITCM, OCRAM are all not used. If you must to use the DTCM, you can reallocate the flexRAM to get the larger DTCM, you can refer to this application note:

Wish it helps you!
