I am trying to generate project with freertos and USB cdc device code, but get error:

Without freertos it is no errors and usb device works. Help me please to fix it.

I use MCUXpresso IDE v11.2.1 [Build 4149] [2020-10-07]

Hi @dinartal

Hope you are doing well!

Could you please help us to verify that you have the USB drivers already imported in your project?

If not , you could add them using the function Mange SDK components.

Please refer to chapter 7. SDK Project Component Management of the MCUXpresso IDE user guide.

If you still can not found the USB drivers in the Component management window.

Maybe , your SDK build did not include the USB drivers. In that case you can uninstall that

SDK , build a new one , and install it.

All the best

Diego.

Hi @dinartal

Many thanks for your reply !

Could you let us know which LPC546xx SDK are you using and which version? is the SDK_2.7.0_LPCXpresso54618?

Could you share your project with its config tools .mex file , or give us details on how to replicate the issue that you are reporting?

Below some images of the testing that I have done, using SDK_2.7.0_LPCXpresso54618 and MCUXpresso IDE v11.2.1 [Build 4149] [2020-10-07]

My peripheral settings for USBFS , yet I have not replicated your error.

My peripheral settings for USBHS, yet I have not replicated your error.

I am sorry for any inconvenience this may cause, as some errors that can be presented with specific software versions, SDKs and settings.

Many thanks

Diego

Hi @dinartal

Thank you for your reply,

After importing your project I was able to get the errors that you are making reference to, even tough the tool is able to generate code , the tool was able to generate USB code , and I did not find compilation issues from my side.

Unfortunately I was not able to replicate the errors that the tools shows while creating a project on my side using the same MCUXpresso 11.2.1 version , thus the same Peripherals tool . Please find my project attached . Let me know if works on your side or If I missed any configuration or driver.

Thanks for your patience

Diego.
