I am trying to build the semc sdram example project for the rt1020evk. There is a linker error for "undefined reference to `__base_NCACHE_REGION'" at line 223 in board.c. Looking at the BOARD_ConfigMPU function it looks like there is some conditional compiltation based on the __MCUEXPRESSO token which I have confirmed is defined. I'm at aloss as to what to try. I am using SDK version 2.7 and mcuexpresso version v11.1.1 [Build 3241]. Any suggestions would be appreciated. I have attached the complete build output.
