Re: [avr-gcc-list] Programming Atmel FPGAs from AVR?

[Colin O'Flynn]

Hello,

IMHO the Atmel programmable logic isn't that great. The tools aren't free - 
you can get time-limited licenses, but why go through that? 

A xilinx CPLD or FPGA is pretty darn cheap - a few dollars some of them. 

I did a similar thing to what you want for Xilinx Spartan II-E FPGAs. One 
bootloader does FPGA and AVR, with files stored in an external DataFLASH.

See http://www.newae.com/loonboard/lub for more details on the system. There's 
an article there that was in CC that will give you some ideas perhaps?

Regards,

 -Colin
