Forum Post: How can I link an asm function to other code section?

Hello,

I would like to link a function, which is written in assembly, to a code section in the internal RAM (section "Code_ExternalRAMTest").

I use the TI compiler 4.9.1

I have tried the name section command (.sect "Code_ExternalRAMTest"), but the compiler throw an error.

I hope somebody can help me?

Best regards,

Philip Hertweck

The function "CP15ICacheDisable" for example:
CP15ICacheDisable:
    MRC     p15, #0, r0, c1, c0, #0
    BIC     r0,  r0, #0x00001000
    MCR     p15, #0, r0, c1, c0, #0
    BX      lr

Memory configuration (a section of linker command file):
MEMORY
{
    INTERNAL_RAM      : org = 0x402F1000  len = 0x3FFF
    EXTERNAL_RAM      : org = 0x80000000  len = 0x40000000
}

SECTIONS
{
    .init    : {
                 init.obj (.text)
               } load > 0x80000000
    .cinit         >  EXTERNAL_RAM
    .text          >  EXTERNAL_RAM
    .stack         >  0x8F000000
    .bss           >  EXTERNAL_RAM
             RUN_START(bss_start)
             RUN_END(bss_end)
    .const         >  EXTERNAL_RAM
    .data          >  EXTERNAL_RAM

    GROUP
    {
        Code_ExternalRAMTest:
         Data_ExternalRAMTest: type=NOINIT
    } LOAD = EXTERNAL_RAM, RUN = INTERNAL_RAM, table(_LINKER_COPY_TABLE)

    .ovly > EXTERNAL_RAM
}
