kind of download speed can I expect from a Dragon using JTAG ?
You are complaining about 6 seconds to program your ATmega32?
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.
In practice I don't think the Dragon supports that.
Solution: buy two Dragons! I have had two connected at the same time
and IIRC there is a dialog box for selecting the desired target. That
a project remembers the Dragon it last talked to.
I have a dead Dragon laying around somewhere. No longer appears on
USB device list. Haven't pursued it but would be nice if it only had
zapped FLASH and could be revived using another Dragon.
