CC3230SF: Getting compiler error on compiling assembler code: unknown directives

Prasun Sinha

Part Number: CC3230SF

I am using simplelink sdk version 7 and compiler 1240.

I am working on application code where the application copies the another application to RAM and executes it.

__asm(" .sect \".text:Run\"\n"
" .clink\n"
" .thumbfunc Run\n"
" .thumb\n"
"Run:\n"
" ldr sp,[r0]\n"
" add r0,r0,#4\n"
" ldr r1,[r0]\n"
" bx r1");

I am getting error:

<inline asm>:2:5: error: unknown directive
.clink
^
<inline asm>:3:5: error: unknown directive
.thumbfunc Run

Please guide.

thanks,

Hi,

I am less familiar with this specifically but as far as I know, these directives are not compatible with TIClang compiler (this is what you are using, right?).

Just for the test, I tried to add it in previous SDK v6.10.00.05 to a TIRTOS and it was OK.

yes, I am using the TIClang compiler. I changed the .sect -> .section and it went away but the other two errors are not and there is not a good document available for the assembler programming.

Hi,

ticlang has different directives. This is why it is not compiling.

Best would be to add compilation flags to see how assembly looks like with ticlang and mimic.

I did it quickly on my side and changed the piece of code so it compiles.

I haven't tested it so give it a try.

If it doesn't work, try to generate and look into the assembly code of any other function.

__asm(" .section .text.myDelay\n"
" .hidden myDelay\n"
" .globl myDelay\n"
" .p2align 1\n"
" .type myDelay STT_FUNC\n"
" .code 16\n"
" .thumb_func\n"
"myDelay:\n"
" subs r0, #1\n"
" bne.n myDelay\n"
" bx lr\n");
