Programming the Series1 (G1) Pano Logic device

The first generation device (Series 1 or G1) has a SPI flash chip which is slightly larger than the bitstream, but it is not big enough for two bitstreams so there is only one bitstream to program.

This makes things easier, but it also means an unexpected error or power outage can BRICK a device.

There are no known bitstreams other than the original Pano Logic bitstreams that implement Pano's protocol so this is a one way update.

There is no way to recover a "bricked" G1 Pano without a JTAG or SPI programmer after flashing a new bitstreams.

Patching progfpga

  • Checkout the pano_progfpga repository.
  • CD into pano_progfpga.
  • Build the patch program.
  • Run patch_progfpga giving agrements specifying type of Pano which will be updated and the path to the binary Xilinx bitstream file to embed into progfpga (note: bitstream must be a raw binary file, not a .bit file).

For example to flash a revision G1 with a new bitstream:

skip@dell-790:~/pano$ git clone https://github.com/skiphansen/pano_progfpga.git

patched/series1/progfpga updated successfully with ../pano_man/xilinx/Pano.bin
progfpga script created successfully.

To flash series1:
   ./progfpga -d
   ./progfpga <ip address>
skip@dell-790:~/pano/pano_progfpga$

Flashing the image over the network

Flashing a Pano device with the patched progfpga utility is exactly the same is as explained in Pano video, namely:

  • Plug the Pano into your local LAN.
  • Turn it on.
  • Wait for it to obtain an IP address via DHCP.
  • Discover it's IP address.
  • Update it.
  • Cross your fingers and wait as the Pano is updated. (Go get coffee, this will take a good amount of time).
  • Power cycle the Pano and enjoy your new image.

For example:

skip@dell-790:~/pano/pano_progfpga$ ./progfpga -d
