STM32Cube FW_H7 V1.8.0 does not properly configure the SPDIFRX input pin

[laurentc]

using STMCubeMx 6.1.2 on a STM32H723

The code generator does not generate this line in hal_msp.c / HAL_SPDIFRX_MspInit()

GPIO_InitStruct.Alternate = GPIO_AF9_SPDIF;

The consequence is that the pin behaves like an output forced to 0 instead of behaving like an input, which obviously prevents SPDIFRX from working.

The problem occurs at least for the 2 first SPDIFRX input lines.

The current version is 6.10.0. Even if v6.1.2 has bugs, you would need to update the version if they got addressed.

Try it in the latest version. A lot has happened between the two. If the bug is still there, please attach the IOC file that shows the issue.
