Default HSE set to 25 MHz for NUCLEO-F722ZE

[Anton Martinsen]

Is it intented for STM32CubeMX drivers for NUCLEO-F722ZE to have 25MHz as HSE input by default? The hardware I bought from ST had an 8MHz oscillator as input for HSE, not 25 MHz.

Hi @Anton Martinsen​ ,

This is reported to our STM32CubeMX development team who will take care to bring required corrections.

Thanks,

Seen the stm32xxxx_hal_conf.h​ contain the wrong HSE_VALUE on occasion as examples moved from EVAL or DISCO series boards with alternate clocking for Ethernet, etc.

​

As a general rule I tend to print CPU and bus speeds to a debug console so I can quickly check they are as expected, helps when dealing with dozens of boards.​

Hi @Community member​ ,

Which example please? What I noted is the difference between stm32f7xx_hal_conf.h and system_stm32f7xx.c regarding HSE_VALUE for same project. This has to be highlighted as well.

It was more of a historic observation, a quick grep yielded this non-comprehensive list

Hello @Anton Martinsen​ 

Thanks for the feedback, issue reported to the tool development team that will plan the correction.
