I have two azbox's, Premium and elite versions. Both smp8634 devices with same eon29lv640 flash. The premium jtag interface works fine but it seems the elite jtag is not working. I can read IDCODE but not IMPCODE or perform any commands. It seems that the TDI pin is not working or the jtag interface is disabled. Does anyone have some suggestions on how to solve this kind of problem. I have tried parallel port jtag and now usbjtag , so it's not the adapter or my connections.
