Hey, I've CC'd this to avr-chat, so we can move the discussion over there...

I just finished making a bootloader for the Xilinx FPGA device. It can load a bitstream file from an external DataFLASH memory, as well as loading the AVR device itself. The resident bootloader takes 198 words right now, so even if you just have a smallish chip like an AtMega88 it isn't taking away that much program memory. Takes 5 seconds to load a Xilinx Sparten IIE 200K gate device. So it isn't that fast if you had a huge device, though there are some tricks you could do to improve the speed several times over. Namely it involves a less flexible hardware setup, where the data lines are hard-wired together. Takes about 35 seconds to download the bitstream over the serial port at 57600 baud. There isn't a lot of details yet, but I've put the code in CVS at http://sourceforge.net/projects/lubloader/ - though there is no schematic yet (Docs still comming) so it will be pretty useless. -Colin _______________________________________________ AVR-GCC-list mailing list AVR-GCC-list@nongnu.org http://lists.nongnu.org/mailman/listinfo/avr-gcc-list
