There are lots of flash programmer out there, but none of them (those I know about) fits my requirement well.
I would like a programmer to be:
* able to program SPI flash chips, * not slow (program 512k bytes in 3 mins), * with a driver whose source code is available (or not difficult to write one), * simple, and * cheap.
There is one that almost does the job,
http://www.malinov.com/Home/sergeys-projects/spi-flash-programmer
but [0] would it be very slow?
Recently I find a chip FT2232x
http://www.ftdichip.com/Products/FT2232C.htm
It seems that the chip's IO could be configured to work in bit-bang mode and thus able to implement as an SPI I/F.
[1] I think it is easy to build a prototype programmer using this chip. Is it? [2] Is the programmer going to meet my requirement?
