flexloader is a small utility to configure SRAM based ALTERA devices. It downloads a code to the device SRAM using an ALTERA ByteBlaster or a compatible JTAG programmer (see flexloader.png for a schematic). It dialogs with it through the parallel interface, using parport. Note that you should have access rights to the parallel port. It should support APEX20K, FLEX10K, FLEX6000 and ACEX1K families, though I only tested it on a FLEX10K10 device. It currently only supports files in raw binary format (.rbf), but others format such as HEX or TTF may be implemented later. It's use is very simple: flexloader /dev/parport0 code.rbf (on linux) flexloader /dev/ppi0 code.rbf (on freebsd) flexloader currently supports a few options switches, you can get them using: flexloader --help
