How to use ram_nocache memory in kendryte.ld file #13

Closed nbenhur closed 1 year ago

nbenhur commented 1 year ago

In the project canmv_k210 there is kendryte.ld linker script. In that ram_nocache is initialized in Memory region. But it is nowhere used in the other part of the linker script. I need clarity on the following below points regarding ram_nocache.

  1. What is the use of ram_nocache?
  2. What is the size of ram_nocache and is it available separately as physical memory along with ram or it is a mirror of ram memory?
  3. Can i use ram_nocache as general purpose ram and extend ram memory?, if so, how to do it?

Please complete the following information

ram_nocache is a mirror of ram, you can not use it as general purpose ram.
