UART RTS CTS

      Dear Mr. Schubert,

      it is not possible to have the RTS/CTS pins of UART_B on connector pins 19/21. No one of the UART_B RTS/CTS pins goes to connector. And yes only UART_A is the only full connected UART on armstoneA9.

      A non-standard solution would be possible. Non-standard means that this is only possible on the armStoneA9 because of a coincidental possibility in the pinmux. But no other armStone will have this feature on these pins.

      You could have an additional full UART with RTS/CTS on pins 19, 20, 23, 24 and a restricted one with only TXD/RXD on pins 21, 22. But this is currently not supported in our device tree. So in fact up to five different UARTs are possible on the regular armStoneA9.
