Kakute F7 board missing T7 in BF

[clone2002]

Hi all, I've had this board for a while, Kakute F7 HDV (http://www.holybro.com/manual/Holybro_Ka...Manual.pdf)
I wanted to use UART7 (just the T7, don't need the Rx) but cannot find it in my CLI (see below, partial resource list).
Based on the pin Id convention below, it looks like it should be E06, but E06 is taken up by "SPI_MOSI 4"--which I have no idea what that is or does.

Tried reflashing BF (4.2.9 and 4.2.11) thinking maybe I tinkered with something at some point and reassigned it without knowing, but T7 is just never there. 

Anyone have the same issue, or have a fix, or can help? I realize I can always just solder to a different open UART, but I'm being stubborn cause the location of the pad was better. I realize this :-)

Thank you!

Code:

resource SERIAL_TX 1 A09
resource SERIAL_TX 2 D05
resource SERIAL_TX 3 B10
resource SERIAL_TX 4 A00
resource SERIAL_TX 6 C06
resource SERIAL_RX 1 A10
resource SERIAL_RX 2 D06
resource SERIAL_RX 3 B11
resource SERIAL_RX 4 A01
resource SERIAL_RX 6 C07
resource SERIAL_RX 7 E07

It looks like Holybro have inadvertently missed the configuration setting for the UART7 TX resource in the KAKUTEF7HDV Betaflight target. I have the same FC but I never even noticed that before. I don't use UART7 though so that is why.

UART7 TX is on the E08 resource, so run the following commands in the CLI to configure it for use...

Code:

resource SERIAL_TX 7 E08

Thank you Snowleopard!
Out of curiosity, what did you use to find the Pin ID for that pad?

Thanks!

It's documented in the F7 MCU datasheet.
