STM32H735RGV6 maximum external crystal frequency

[Ersin Kuscu]

Hello dear,

I will use "STM32H735RGV6" with an external crystal. In the datasheet, it is stated that "External oscillators: 4-50 MHz HSE". However, in CubeIde I cannot assign 50MHz since it is limited to 48MHz.

Could you help with this issue?

I was using one of the previous versions and when I updated CubeIde then the issue has been solved.

Hello @Ersin Kuşçu​,

Let me first welcome you to the Community :)

Glad to know you overcame this problem.

It was a limitation with the older versions of STM32CubeMx, and it's fixed after that.
