i.mx RT1160 increase NCACHE memory region

Cococarbine — Mon, 27 Sep 2021 21:57:18 GMT

Hello,

I have an 1160 evk, with what I assume has two 256Mb Ram chips. I am running the camera yuv sdk demo, and I wanted to increase the NCACHE region to get a larger image buffer (8 3Mb frames). I tried increasing the size from 0x10000000 to 0x20000000 (16Mb to 32), but the program crashes. Is there anything else I need to do to increase the memory availability?

Thanks,
Ed

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1）Is there anything else I need to do to increase the memory availability?
-- As we know, the the MIMXRT1160-EVK board has two W9825G6KH, it means that the total size of the on-board SDRAM is 64 MB.
In the below figure, it consist of two parts: BOARD_SDRAM and NCACHE_REGION, when you increase the size of NCACHE_REGION to 32 MB from 16 MB, BOARD_SDRAM needs to decrease the same size.

Hope it helps.
Have a great day,
TIC
