Always include your chip part number when asking a question.
You can use HAL_MPU_ConfigRegion to disable cache for a memory range.

STM32F767.
If caches are enabled tcpip msg fetch is not working so need to make lwip rx tx buffers as non cacheable

yes Thank you.
How to select the buffer region.
Do we need to place the buffers in particular memory region before making that region non cacheable

You will need to make the buffers aligned to cache line boundaries, but they don't need to be located anywhere in particular.

Can we make those buffers non cacheable.
2020-07-17 06:51 AM
Yes, by using HAL_MPU_ConfigRegion. We're going in circles here. I'm not going to write the code for you for free. Maybe someone else will.

I just wanted to know which are the buffers I need to make non cacheabpe in lwip
