For flashing a bootloader yes, you need a UART (there may be options like RS232<->UART converter) and the easiest way is tu buy a USB<->TTL adapter. Cheap like hell.

Right, search for "usb ttl" on eBay and you can find them for less than 3 $ (with Free Shipping/Buy Now), including cables. Seeed only sells more specialized usb to serial boards as far as I can see.

Can do your own as well (e.g. http://roboforum.ru/forum4/topic10592-15.html#p232256 - sorry, it's in Russian). If you use a scope you need other convenient tools, so it's a good investment. You can also consider more complicated tools like BusPirate. Does an awful lot of things but it will take time to learn how to handle it.

Also, there was a piece of software that did *.hex to *.bin convertation. Will try to find it for you - can't remember what's the name of it...

On Linux you can use:

Code:

objcopy -I ihex -O binary file.hex file.bin

Anyway, I guess the problem is not the differently formatted hex files, but that eDesign(?) has added some checksum or "certificate" to make sure only their firmwares can be installed. Effectively shooting themselves in the foot, since their firmware is a joke compared to the independent third-party firmware from Benf.
