Getting board SDRAM working with RT1050EVKB

My program has outgrown the internal RT1050 RAM and I need to use the external SDRAM on the EVK. I tried using the example FreeRTOS Hello World project as a known good. I am having issues with my project and the Hello World project. I either get hard faults or the program crashes at the clock configuration.

 

I followed the "Using the MIMXRT1050-EVK(B) with MCUXpresso IDE v10.2.1" to try and configure my project to use the SDRAM. I noticed that the SDRAM example that is used in the document is for linking only to the SDRAM. I need to store the project and flash and use the SDRAM as my main memory. I tried the stock linker script and also tried changing the addresses to 0x8xxxxxx instead of 0x4xxxxxx, since that is the location of the RAM in the MCU Settings menu.

 

There is probably some setting I am missing. Please let me know if something jumps out.
