Can't help you much here, but I've been lately looking for a cheap JZ4760 based platform for testing and development, so learning about the existence of this device is great news for me.
Does anyone know of other JZ4760 devices I should consider? Rgds. 2011/8/5 Uli Raich <[email protected]> > Hi all,**** > > I am trying to get usbboot to work on a Ronzi A3 which uses the JZ4760.
