Done, except for C3-UART-TX/RX. This brings up an important point - should that be the CLI UART? or if we want a back channel to other cards, does that HAVE to be a difference UART? Maybe we can do both via GPIO tri-state control?
We're using USART3 for the CLI. Pins we have available that have UART alternate functions: PA0 - 23 - UART4_TX PA1 - 24 - UART4_RX PA2 - 25 - USART2_TX PA3 - 26 - USART2_RX PC6 - 63 - USART6_TX PC7 - 64 - USART6_RX
Free pins that don't do UARTs: PB0, PB1, PB2, PC13, PD14, PD15, PE4, PE5, PE6, PE9
Connected up USART6; waiting for firmware folks to OK.
No longer relevant for the v6 since we switched to the Octavo.
Bring up to v2 backplane!
