To clarify one thing, when the __PRODUCT_JALAPENO or __PRODUCT_LITTLE_SINGLE is selected, the crystal used for the MCU should be 16MHz. However for SINGLE or MINIRIG models, then the crystal
used should be 12MHz, otherwise the Frequency of the ASICs is going to be incorrectly calculated (that is where you get 320MHz speed report, etc).

Thanks for the reply Nasser, although I think you're mistaken here. There is no Product_Jalapeno or Product_Little_Single, the firmware is entirely custom on an ARM chip. The 320MHz was measured at the clk_out pin as the divided by 64 version of the onboard PLL while using divide by two internal divisor.

Is there an email I can reach you at? I would like to ask a few technical questions about the chip in regards to setting it up to use an undivided version of the onboard PLL as the chip clock. I will PM you my contact details.
