I'm in the UK, using the Keil C51 toolset, and the Triscend E5. Being in Europe (or, should I say, outside the USA?) I have to use a "dongle" (hardware key) with the Keil tools. Far from being transparent, the Keil dongle seems to significantly mess-up the communication bewteen the parallel port and the Triscend JTAG. Keil's knowledge base article http://www.keil.com/support/docs/1788.htm suggests that this may not be an uncommon experience. Has anyone else experienced problems with the Keil dongle - particularly in connection with the Triscend E5? Any tips?
We have a Dell laptop, with an external disc drive. The external disc drive will not function with the Keil Dongle in place (if anyone has any suggestions as to how to get round this - it would be appreciated). This is a minor inconvenience though when compared to the problem of forgetting your dongle when going on a site visit to commision software/hardware. Put it this way though - you only tend to forget once! Yours, Richard.
See in your BIOS Setup configuration of your parallel port, e.g. Peripheral setup->Parallel Ports->Mode and be sure that port using dongle in SPP mode, not in ECP, ECP+EPP, EPP or Bi-directional.
Which goes to emphasise just what a pain the dongle is! SO I have to reboot my computer & reconfigure the BIOS just to get this stupid dongle to work properly! Surely, if Keil really must use this thing, they should come up with something which doesn't mess up the whole of the rest of the system!!?? :-0 Come on guys, we're in the 21st Century now - there must be a better way!!??
We had the same kind of problems with a Dell laptop and data I-O chiplab programmer. The dongle short circuits pins 17 upto 25 (as GND pins) but Dell uses some of them to see if a external drive is connected. So you should wire these pins around the dongle. you should keep ONE GND connection in place, obviously. Good luck- Alex.
Yeah.. and it is amazing what you can do with a disassembler and a little effort *hint* :) I mean, I paid for the software already, why should I mess around with some silly dongle protection? That is no way to treat your paying customers, if you ask me!
