I need cubemx 5.0.6 version for custom HID HS in STM32H743iit6.I also checked new version cubemx 6.11 but its not working. Because i am using ULPI USB3300 for high speed (HS) USB , it require PLL clock 480MHz. But newer cubemx not supported 480MHz instead it limit the PLL clock source to 66MHz.
NOTE: Example's code's generated in the cumemx 5.0.6

Hello,
it require PLL clock 480MHz. But newer cubemx not supported 480MHz instead it limit the PLL clock source to 66MHz.
Not sure I understand this statement. How did you conclude that the latest version of CubeMx does not allow you to set 480Mhz for the MCU?

Hello,
MCU clock speed supported 480MHz. But I am talking abut USB Clock Speed in STM32H7, It's limit the clock speed to 66MHz. This clock speed ok for the Custom HID(FS Mode). But , When i am using Custom HID (HS Mode) Integrate with the ULPI USB3300, It actually required PLL clock speed 480MHz. But Newer version of the cubemx Not support that.
What is the Reason behind this?, can you help me...!
Here I attached Clock Configuration...:backhand_index_pointing_down::backhand_index_pointing_down::backhand_index_pointing_down:

Hello,
USB clock can’t be set at 480MHz. USB clock mux is set to PLL1 as clock source as shown in your screenshot. You need to select PLL3Q or RC48 to feed USB clock by a 48MHz source.

Hello,
In OpenH7xxi-c development kit, Demo code for Custom HID (HS) USB Clock speed supported 480MHz Without any error.
This configuration done by the cubemx 5.0.6 version. But newer Version not allow to set 480MHz. I am Tested all the available option like 1)Endpoint Interrupt Preemption 2)ULPI USB3300 hardware 3)Report Descriptor and 4)increase Heap & Stack size , that's are not help me. My Guess is Problem in the USB Clock (USB High Speed mode).
So i am unable to communicate the Custom HID in the High speed mode(480MBits/s).
Also i am check the Cubemx 5.0.6 version in the Website, but it not available. Can you Have any better idea for communicating Custom HID for High speed mode?
Here i am attached cubemx 5.0.6 version Clock configuration...

Primary ULPI clock isnt 480 but 60x8bit = USBHS
Secondary maybe MX5.0 show and set this clock and new make some next cross checks. Search in MX FS USB set...
And MX is only generator ... compare resultcode with v5 and corect it in user part . Exist many ways.
And too USB HS is more usable on crystal clock as on RC
