How to configure PE to enable USB in CW10.2

[bugs]

We have system use Kinetis MK60N512VMD10 with 10MHz crystal, I tried to use PE to configure the BSP, everything seems working except the USB doesn't work. The Virtual Com program doesn't provide a COM port. I have been using MQX3.7 and it works fine, but with MQX3.8+PE, It seems somewhere not right.

I am using the TWR-K60 BSP, added a new MK60 controller, and configure it according to the old one, but the generated code doesn't have Cpu_MCGAutoTrim() function, so I commented out the Cpu_MCGAutoTrim() function call, and get the BSP and VCOM compiled, but VCOM doesn't work.

Which option should I use to enable PE to generate Cpu_MCGAutoTrim() function?

What else should I do to let USB works? I already configred the clock settings and clock configurations.

Hardly claim to be expert on configuring hardware clocks. So I went to the methods tab for the processor component to look at MCGAutoTrim, and hovered to get the help for it. It says that the method will be enabled only if bus clock derives its reference from an external source. Your screenshot shows the external reference clock disabled. So... this method is disabled. THere are other requirements as well. Check out the help for guidance, you may find useful hints. And I hope this helps at least a little.

HI James,

We are also trying to generate the MCGAutoTrim Function using standalone PE for use with IAR compiler for K60 Processor.
We are trying to integrate PE generated drivers to the BSP for a custom board.
The MCGAutoTrim function is grayed out (meaning it cannot be generated) for whatever clock configuration setting is used.

If we put the generated PE_LDD.h file inside the Cloned BSP, it keeps complaining about the MCGAutoTrim function as it is not getting generated from the PE.

Is there a way out?

Thanks in advance

Hello,

please find the attached screen-shot. It should help you to switch the method to enabled state.

The TWR-K60 BSP also has the OSCERCLK disabled, why it could generate that function?

Hello,

we would need the project in order to analyse (reproduce) the problem. Could you please post it here?

Check TWRK60 BSP's PE settings in Advanced mode. It shows OSCERCLK is disabled.
