i.MXRT1010: How to configure FlexRAM?

yokonav — Wed, 26 Feb 2020 17:21:04 GMT

My current (default) FlexRAM settings are Flash: 16MB, SRAM_DTC: 32KB, SRAM_ITC: 32KB, SRAM_OC: 32KB NCACHE_REGION: 32 KB. My program needs bigger SRAM_DTC (64KB). I can change SRAM_DTC size in MCUExpresso > C/C++ Build > MCU Settings. But I see some code in board.board.c -> BOARD_ConfigMPU() related to RAM configuration. Do I need to change them, too? Can you please let me know the exact procedure to increase/adjust RAM size?

IMXRT1011 with FlexRam configured as flat 128kB.

Hello, i m looking for a flat imxrt1011 128kB RAM

Reading the application notes and the knowledge Base "Reallocatin the FlexRAM" i reconfigure the ram and adding only FLASH and a NCACHE_REGION 0x0 to 0x20000 i can compile a C++ project.

But when the main runs the idle while(true) i++ … there is always exception.

Please is there a complete example C++ project to reconfigure IMXRT1011 with 128kB of RAM?

Thank you!
