Does anyone know if it's possible to access the PX5's OTG USB using one of the existing external USB connections (without having to pull the head unit apart)? I'm trying to get a USB connection for ADB and came across this on the wiki:
I noticed on the MTCD schematic that the MCU has pins for CTL_RECOVERY and CTL_WAKEUP, which leads me to believe it might be possible to program the PX5 in place using some sort key combination. I tried the wiki instructions, but can't get the PX5 get picked up at all on the USB connection.
Bootloader mode
Holding the power button while turning on the unit will get you into bootloader mode. **This is battery power not acc power** The screen will be black but plugging in a usb to the front usb will prompt the PC to install the RockChip bootloader drivers - this might help http://www.cnx-software.com/2013/11...install-rockchip-usb-drivers-in-windows-xp78/
