Problem with PD9 by FSMC Interface on Nucleo-F413ZH board

Hello

I'm using a Nucleo-F413ZH board with System Workbench for STM32, Currently I try to startup the FSMC Interfcae 16 Bit for my QVGA Display with SSD2119. I config the Ports and the FSMC peripheral OK DB15 (PD10 is not Connected on Nucelon Board here I made a wire connection to the µC) . FSMC is located to Bank1 D0 - D15 are ok, but on D14 connected on PD9 I measure a permanent high, can anyone imagine why? I check my soldering contact on PD10 with a microscope and everything looks good. 

Thanks for your help

Daniel

Hello!

PD9 is connected to stlink TX (serial port.)

Remove the jumper SB6

Thanks,  That PD9 is connected via SB6 I had overlooked completely

But I understand the schematic and the datasheet correct, I can remove SB6 and I didn't need STLK_TX for communication with the Nucleon-Board, because

I use the USB Connection. Please improve me if I'm wrong

Best regards

Daniel
