Compiler/PROCESSOR-SDK-AM437X: Compiler addressing of const variable for am437x PRU

Tool/software: TI C/C++ Compiler

In am437x PRU C program, I use a const array variable, I find that this variable are not addressed to program areas, but to memory areas.

How can I set it to address the program area?

I think you want your const array, which is in the section .rodata or .rofardata, to be allocated on PAGE 0 next to the executable in the section .text. This is not supported. It must be allocated on PAGE 1 next to all the other data sections. For further detail, please search the PRU compiler manual for the section titled Specifying Where to Allocate Sections in Memory.

Thanks and regards,
