CCS/PROCESSOR-SDK-AM437X: Linker errors

Part Number: PROCESSOR-SDK-AM437X

Tool/software: Code Composer Studio

Hi,

Hi,

I think I have a similar problem with my CCS setup. I have created an IO link project based on TIDA-010016.

<C:/ti/pdk_am437x_1_0_15/packages/ti/build/am437x/config_am437x_a9.bld> is included as described in this forum.

Compiling without problems, I get a linker error at the end:

makefile:251: recipe for target 'EPW600_AM437x.out' failed

This is how my *.lds file starts with:

MEMORY
{
    OCMCRAM (RWX) :     org = 0x40300000, len = 0x20000
    L2SRAM (RWX) :      org = 0x40500000, len = 0x40000
    APP_CODE_MEM :      org = 0x80000000, len = 0x200000
    APP_CACHED_DATA_MEM :    org = 0x80200000, len = 0x1400000
    APP_UNCACHED_DATA_BLK3_MEM :  org = 0xa0000000, len = 0x200000
    APP_CACHED_DATA_BLK1_MEM :   org = 0x81600000, len = 0xf400000
    APP_CACHED_DATA_BLK2_MEM :   org = 0x90a00000, len = 0x8000000
}

REGION_ALIAS("REGION_BSS", APP_CACHED_DATA_MEM);
REGION_ALIAS("REGION_TEXT", APP_CODE_MEM);
REGION_ALIAS("REGION_DATA", APP_CACHED_DATA_MEM);
REGION_ALIAS("REGION_STACK", APP_CACHED_DATA_MEM);
REGION_ALIAS("REGION_HEAP", APP_CACHED_DATA_MEM);
REGION_ALIAS("REGION_ARM_EXTAB", APP_CACHED_DATA_MEM);
REGION_ALIAS("REGION_ARM_EXIDX", APP_CACHED_DATA_MEM);

The created <.\configPkg\linker.cmd> shows content (memory area and region alias declaration) in the right way.
What could be the reason for the redeclarations? Any other file(s) involved in the mapping?

Best regards,
Thomas
