BIOS C6670 L1D Cache disable

Hi experts,

I want to do a "Cache_disable( Cache_Type_L1D );" in the bios config file.

this are the lines i have already in my code:

var Cache = xdc.useModule('ti.sysbios.hal.Cache');
var ti_sysbios_family_c66_Cache = xdc.useModule('ti.sysbios.family.c66.Cache');
ti_sysbios_family_c66_Cache.atomicBlockSize = 0;

But this is not working (wrong syntax):

var C66CSIZE = new ti_sysbios_family_c66_Cache.Size;
C66CSIZE.l1dSize = ti_sysbios_family_c66_Cache.Cache_L1Size_0K;

Please Help!

Best regards,
Matthias
