Other Parts Discussed in Thread: OMAPL138
This is a purely educational exercise for which I need some help. I'm rebuilding a very old SDK for the omapl137 component (the ARM UBL) with the latest cgt for arm.
I'm getting the following warning:
source/boot.c|88| warning #1119-D: this assembly directive potentially unsafe inside a function
at this location:
...
// Setup the stack pointer
asm(" LDR sp,_stack");
asm(" SUB sp,sp,#4");
asm(" BIC sp, sp, #7");
// Call to main entry point
main();
asm("_stack:");
asm(" .word STACKStart"); <---
...
Any suggestion of another SDK or board support I can look at, as a reference for a baremetal arm initialization?
I have another thread open which I have completed answering my own questions :).
