Disable CORE 1 and CORE 1 cache to allocate another IRAM segment of 32k

Postby safetycaptain » Thu May 09, 2019 9:21 pm

Hello all,

I'm wondering if anyone has ventured into getting another 32k of IRAM when disabling core 1.
I'll be diving into this soon, just figured i would put out some feelers into the community.

It should happen automatically when you disable core 1 in menuconfig.

It doesn't reserve the region so it can be added to iram heap but it isn't available to the linker for iram.
