Linux: TDA2Px IPU_RAM M4

Tool/software: Linux

Hi,

My IPU code is loaded by remoteproc.I have the problem that the address 0x0000000 ( contains interrupt vector and reset function) is overwritten by IPU_RAM after enabling the cache. I solved this by copying the memory content of 0x000000 to 0x55020000 during the assembler startup code. 

Is there another option to preload the IPU_RAM? Linker File? Is this a normal behavior?

Thanks
Andreas
