Forum Post: TI Compiler Compilation Error When Passing Address to ARM inline Assembly Code

Dear Supporters:

I intend to copy data from RAM to A8 Cortex L2 cache way via Preload Engine(PLE).

I am currently stuck on writing the virtual address to the PLE CP15(3.2.64 c11). I wrote an api as below,

but the TI compiler has complained about its format. Could anyone provide expertise on how to fix

this problem?

void Write_PLEStartAddress (UINT32 start_addr)
{
       asm volatile("     mcr p15, #0, %0, c11, c5, #0" :: "r"(start_addr));
}

compiler error,

"

line 1266: error: expected a "("

line 1266: error: expected a ")"

"

My platform info: TMS320DM8148 (Vision-Mid) 

600-MHz ARM® Cortex™-A8 (r3p2)RISC MPU

500-MHz C674x™ VLIW DSP

200-MHz M3-ISS/M3-HDVPSS 

Thank you in advance,
