We took part of in the original HAB disclosure process for the NXP i.MX series and we carry on testing these parts. Please see https://github.com/f-secure-foundry/advisories https://github.com/f-secure-foundry/advisories Of course all P/Ns used for the Mk II have a patched boot ROM, please see https://github.com/f-secure-foundry/usbarmory/wiki/Secure-boot-(Mk-II)#security-information https://github.com/f-secure-foundry/usbarmory/wiki/Secure-bo.... The original Mk I was 6 layers in the end, the Mk II is also 6 layers. And yes the BOM cost is considerable due to its specifications. The i.MX SoC core we use is comparable to a 1st gen Raspberry PI in speed, but of course slower than newer multi-core ones. However security and form factor, rather than pure speed, is our goal. For the intent and purposes of the board performance is more than adequate.
