I use STM32F217 USB-HS Demo to STM3221G-EVA board(STM32F217IG 176pin) and it works well,

now I have a project to implement preceding function but I only have STM32F217VG(100 pin) without PH4(ULPI_NXT) and PI11(ULPI_DIR). May I change PH4 to other GPIO and how to alter codes or other method to solve it? Many thanks.

You could observe the alternative pins PC3 and PC2 in the

Modify the code that enables/configures the GPIO pins and clocks.
