how can i bypass cache

Question

how can i make my onchip mem be uncached when accessed?

i searched the forum, there are several methods:

bit31, ldwio/stwio, and dcache_flush function,

but how were them used?

i tried them but failed?

can someone give me a detailed example?

thanks

Hello sjtuj,

A lot of information about the Nios II cache functions can be found in the “Nios II Software Developer’s Handbook”. I think chapter 7 “Cache & Tightly-Coupled Memory” will bring you further.
