1. the openwince jtag project has support for more flash type. it works on general jtag devices,
eg, xscale,arm,cpld,fpga. it support programming to a lot of cfi flash memory.
if you want to build a universal flash programmer through jtag, this should be what you want.
but programming flash via jtag is very very slow!
flash file --> linux pc printer port --> jtag --> fpga...etc ---> cfi flash
you have to add nios board bus data to use it.
2. if you want to program mcu, cpld , other than cfi flash.
you have to check each vendors's support. there is nothing to do with nios.
but you can develop a nios board as a jtag controller to program other jtag devices.
3. the sopc builder's flash tools support intel and amd devices. its purpose is to download
design to flash on development boards. there are many other posts on the forum, just search them.

--- Quote End --- I've heard about JTAG programming speed. It will be harder, because there are many MCU CPLD etc vendors. I really apreciate your help, I'm not confussed anymore. Have a nice day.
