Hi, I haven't even received my Dragon yet, probably in 10 days or so, but I already have questions, following study of the avrdude man page.
- I am currently using a parallel port DIY cable, ISP programming then, and I notice that it's very slow to download stuff, a bit painful as I download numerous times a day while debugging. I would say about 5KB/s maximum. I intend to use JTAG intead of ISP, with my Dragon. What kind of download speed can I expect from a Dragon using JTAG ? - My current project actually uses two distinct board. The main board which is the actual product I am designing, and another board connected to it, which simulates the hardware that my project is going to be connected to once finished. Anyway, I keep having to unplug the ISP connector from one board to that of the other board, and vice versa, every time I make a change to either board. A bit of a pain, and prone to errors ! Yes... I did download the code destined to board A.. into board B.... big badaboom !! :-O :-/ I understand that JTAg, thanks to its very nature, allows to chain devices, allowing to talk with any one dvice from a single JTAG port. - So, is avrdude (assuming the Dragon itself is able to do it?) capable of selecting which of my two AVR chips it is to talk to (and how do I specify the one I want to select ?), or will I have to have two distinct JTAG headers, one for each board, just like I have two separate ISP header currently ? Thanks ! :-) Regards, -- Vince, sooo impatient to receive his Dragon, can't stay in place ! _______________________________________________ AVR-chat mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-chat
