I have scoped with no significant voltage drop - besides the IOIO can enter this locked up state purely while left to it's own devices with no load changes
I'm using an external regulator because the Nexus 5 charge current is incredibly sensitive to voltage and needs just over 5v to maintain a charge. I supply this on the device side of the fuse to avoid the drop over that. (same glitch that occurs with onboard regulator anyway) - I've discovered the reason I see the problem more often with fast charge is fastcharge reconnects the USB host as it has to be run after a cable is connected - making for 2 chances to lock up the ioio each time instead of 1 - so for simplicity I'll continue all testing without fast charge. - Is there a way to see if the PIC itself has locked up? All I know is you can cycle the cable, and reboot the phone but the only fix after this situation is an IOIO reboot, so it's definitely a state that exists within the USB controller or PIC itself - Same behaviour on two N5s and two different IOIOs James On Thursday, December 31, 2015 at 10:53:38 PM UTC, James Warner wrote: > > Having some odd troubles with the IOIO-OTG > > Running HelloIOIO using latest software/firmware and Hello IOIO app - have > an odd problem every few USB reconnects when using a Nexus 5.
