There is a strange problem in my project,need help...

 

In this projest ,there are 1 FPGA and 2 DSP,they connected by cluster bus,while FPGA is the HOST.

 

When I load dsp by cluster bus ,sometimes it may be failed.

 

Then I found that in these cases , HBG do not follow the HBR signal .

 

In my opinion, when HBR is enable , HBG should be enable too , in a little time later,but it wasn't.

 

It means that HBR_N=0 and HBG_N=1 kept for a very long time , in fact ,no end.

 

Then I tryed to use "back off",control the BOFF singal , but it not work ,too.

 

 

 

PS. dsp0 always could be loaded,but dsp1 only could be booted after dsp0 loaded,for example , I load dsp0 first,and then load dsp1,it will be ok, but if Iload dsp 1 first, i will be failed.
