RT os and loader are loaded to PSRAM as well, what to do? Is it possible to load RTOS to normal RAM (even better ROM) in order to allocate more than 16 KB of stack?
Yeah, sorry this is a Keil forum.
Presumably no_init_size is a variable/symbol used elsewhere in the script, or imported in your source. You'll have to dig to find where the stack is actually placed into a section.
