Hello everyone!

How could I pass a string in an ASM function?

I have this function which jumps to some address which I want to specify as parameter.

void jumpAddr(uint32_t address){
   asm(" MOV R0, #Here_address ");
}

How can I specify the address 10000 as a function parameter?

Hi Mihai,

You can't do that with the CCS / TI ARM compiler, unfortunately.

Oh, that's bad! Is there any way that I can simulate this? Like writing to a specific address in flash where I want to jump and then with this function to jump there and then to my desired location?

That would be a possible solution, you would have to make sure to tell the linker to place the variables at the expected address. If you are planing to include a lot of assembly code it could make sense to look into using assembly functions and how you call these from C code.
