Please specify the rules for using USE_AMP

I have put LWIP on cpu1 and the main code on cpu0. When I try to use SD card on cpu0 I run into trouble because USE_AMP seems to prevent this. Building BSP for cpu1 with USE_AMP will cause interrupt for lwip not to be handled.

 

I suspect that there are other combinations that don't work. Xilinx, please specify the rules.

Re: Please specify the rules for using USE_AMP

I have also tried this and run into similar issues. LWIP on CPU 1 with USE_AMP=1.

Is there an explanation for why this does not work?
Are there recommendations for running LWIP in an AMP configuration?
Does the LWIP need to be on CPU 0?
