Hi Bas and Nils, I think you are talking about below port: There is an hidden connection in the trendtac, which is an additional usb port. I have connected a usb connector + wifi stick to it. Used http://www.flickr.com/photos/trendtac/ pictures. if the uart+communication still works, then we do not need jtag, but can use telnet to hook up a console. Hook up a serial console via the battery compartment would be the same I would guess ? Hi Ard,
The cas-3plus costs 61.50 euro. I have no experience with this one, weird, well my cable tv is good enough ;-) It looks like it is equiped with 20 pins cable, jtag standard? For rs232 (hook up to serial console) we may use below one. http://nl.farnell.com/ftdi/usb-com232-plus-2/module-dev-usb-rs232-2-com-port/dp/1817171?in_merch=New Products&MER=i-9b10-00001144 Hi Nikolaus, I am looking forward to the results and documentation of your jtag setup. I have below questions with respect to jtag and jz4730: - Where to attach the jtag interface connections to the jz4730 (trendtac) ? Maybe the hidden usb port or ttyS0 serial port ? - What kind of Jtag access serial protocols/testmodes are needed for jz4730 (trendtac epc700) ? - do we need additional software for jtag communication to be able to program nandflash with uboot ? - Is there a possibility to 'heal' bad nand blocks via jtag commands ?
