Hi Hiroshi, I just tried this on my beagleboard and I'm not sure if it worked. First, did you forget to add that you need "mem=122m" in the bootargs? Also do you need to add in the addresses like: sudo modprobe bridgedriver phys_mempool_base=0x87a00000 phys_mempool_size=0x600000 base_img=/home/rick/dspbridge_binaries/ddspbase_tiomap3430.dof64P Anyway, when I followed the instructions (except for above) I get: > sudo modprobe bridgedriver phys_mempool_base=0x87a00000 phys_mempool_size=0x60 0000 base_img=/home/rick/dspbridge_binaries/ddspbase_tiomap3430.dof64P > lsmod Module Size Used by bridgedriver 356488 0 > cat /proc/interrupts | grep Dsp 26: 3 INTC DspBridge 28: 0 INTC DspBridge > /home/rick/dspbridge_binaries/ping.out > > cat /proc/interrupts | grep Dsp 26: 4 INTC DspBridge 28: 0 INTC DspBridge After this, no matter how many times I run ping, I get the same number of interrupts. How do I know ping is really working?
