I have posted my latest series here [1] based upon that from Will [2] which attempts to fix the EMU CD based upon the inputs from this thread. It is working on my omap4460 panda.There are some differences between 4430 and 4460 here. Can you test on 4430 as well?
No problem. I tested on an OMAP4430 ES2.2 EMU blaze this morning and it is also working. By the way, from an EMU power domain perspective the omap4430 and omap4460 behave the same, that is the PD is always set to OFF state and so will transition to OFF when ever the EMU CD idles. So same problem exists when using PMU and CTI. Cheers Jon
