RISC-V target board support

Does ChipWhisperer support any RISC-V target board?
The documentation lists the NAE-CW308T-FE310 target board, but it shows “obsolete” at the Mouser website.

Is there any other RISC-V target that can be used on the UFO target platform?

Thanks,
Christine

At the moment we have a couple of RISC-V target options on our FPGA targets:

  1. The neorv32 on our CW312T-iCE40 (which is part of the CW-Husky kit)
  2. The lowRISC Ibex on our CW305 or CW312T-A35

And one more which isn’t available quite yet: we’ve made a target board for the new RP2350, which has both ARM and RISC-V cores.

Thanks for the info. We bought the ChipWhisperer-Lite recently and are trying it out. For these two soft RISC-V core target options, which starter kit will be mostly useful? We are considering either the CW level-1 or the level-2 kit. The CW-Husky seems to be a closed platform, not having the UFO target board. We would like to try out different CPU architecture targets down the road.

Thanks for the info. Do you have a timeline when this board become available?

Neither the level 1 nor the level 2 kit are useful for these targets.

For the CW305 target, you don’t need anything else (other than the CW-Lite you currently have).

For the smaller FPGA targets (iCE40 and A35) you would need to purchase the Husky kit since that is the only way to get the CW313 board that is required to interface with those targets (and the same is true of the not-yet-released RP2350 target).

I’m not sure what you mean by Husky being a closed platform; it is fully open-source. The CW308 UFO board is replaced by the CW313 to lower costs and to provide a more convenient form-factor. Moreover existing CW308 target boards can be used with it, with our target adapter boards.

I don’t have a timeline for the RP2350 yet. The board exists and is functional (it was used for Raspberry Pi’s hacking challenge), but we haven’t pushed it into production yet.

Thanks for the clarification. This helps a lot!
From the CW-Husky link online, https://www.newae.com/products/nae-cwhusky, it shows an enclosure box. We could not tell whether we can change the target board inside the box. The Level 1 and Level 2 kit pictures seem to indicate that we could swamp the target board, using the same capture board.

It sounds like Husky kit is the right option to go.

Ah, now I understand the confusion. While CW-Lite is available in a single-board, capture+target version, CW-Husky only has capture functionality (much like our no longer available CW-Pro).

Husky is compatible with all the targets you could use with the CW-Lite (or Pro) and vice-versa, including the full CW308 family of targets. On the Husky crowdsupply page, there is a picture of the Husky kit contents here: ChipWhisperer-Husky | Crowd Supply

The red board next to the blue Husky is the new CW313 target carrier board.

Oh, Husky is a capture board only. We totally missed that.
Thanks for the link to the picture. So we should purchase the Husky, the CW313 target carrier board in red, and other blue target boards in blue which can be fit in the CW313, is that right?

Correct- Husky is only sold as a full kit at the moment, either from CrowdSupply, or Mouser.
