[> About This is a fjmem compatible core for the Mixxeo and M1 boards . It provides support to program the onboard parallel flash with UrJTAG . [> Requirements - Mixxeo or Milkymist One board :) - UrJTAG compatible JTAG pod - PLD enabled (i.e. recent) UrJTAG - Xilinx ISE (WebPack edition is sufficient) [> Howto Build the flasher with: $ cd boards/[mixxeo or milkymist-one]/synthesis $ make -f Makefile.xst all This will result in a bitstream which is loaded into the FPGA before flashing. It provides an interface compatible with the fjmem bus driver of UrJTAG. After building and installing UrJTAG start it by $ jtag Execute the following commands on the CLI to program the flash cable milkymist detect pld load /path/to/system.bit (eg. build/system.bit) initbus fjmem opcode=000010 detectflash 0 flashmem 0 /path/to/system.bin Only binary files are supported by UrJTAG atm. [> Debugging On M1: LED1 should blink with approx. 1Hz after loading the bitstream. LED2 toggles with a transition to the DR_UPDATE state of the TAP state machine. On Mixxeo, the single LED is the XOR of those two. [> References  http://www.milkymist.org  http://urjtag.org
