Hello,
i'm trying to stop a running executable on the ppc405 placed on a virtex2-pro. Currently i'm trying to do this by pulling the clock-input (CPM405CLOCK) to the ppc to 1 (simple by using a multiplexed bufg switching between normal clock( ppc_clk_), and net_vcc0), thus imitating kind of power management as i read in the ppc405-block-reference-guide. This approach won't work, the ppc is not responding when normal clock operation continues. My next intention was to suspend the ppc in software, though there is no halt-instruction. In further threads i read setting the msr[13]-bit will put the ppc to sleep and certain interrupts will awaken it again. So, if anyone has done this before or has further suggestions how to do this any help would be very useful. Thanks.
Best regards, Patrick Siegel
