AVR-Chat

He had a dragon, and had some boards that a previous person had put into debug mode so he couldn't program them.  He couldn't turn off the DWEN fuse with his Dragon so I loaned him my mk2, which he used for a while.  Then he told me he could set fuses with the MK2, but not program and program with the Dragon but not set fuses.

I suggested that he only use an ISP so that his employees don't have the ability to make as many mistakes when they burn the parts but he wants to stick with the Dragon for now until he ramps up production.

Off the top of my head if your virgin parts do not come with JTAG enabled you must have an ISP or parallel programmer (Dragon comes to mind as having all 3) to initially set the JTAG fuse appropriately.

Think an ISP is only $30.
