lpc54608 usb1 cdc

hi,

i am trying to configure usb1 for hs usb cdc mode on a prototyped board using the lpc54608.

starting from dev_cdc_vcom_lite_bm, I have set serial_port_type_usbcdc = 1, and usb_device_config_lpcip3511hs =1, while setting

#define USB_DEVICE_CONFIG_LPCIP3511FS (0u)

#define SERIAL_PORT_TYPE_UART (0U)

these are defined in serial_manager.h and usb_device_config.h

the first problem to arise is that, upon setting the port type to usbcdc rather than uart, I am unable to build. second, if I prevent error from happening, I am still unable to connect. so, I am wondering, what steps am I missing to configure usb1 for cdc.

thank you!

how I prevent (//commented out code is what came with sdk; my my modification is below)

/*******************************************************************************

HI,

I need reproduce first, which IDE do you work with and what is your SDK version?

Regards

Jun Zhang

I have just downloaded the latest SDK to see if that helped, so that is 2.6. I am using IAR embedded workbench.

thanks!

Hi Eileen Radzwion,

Just tested SDK2.6.0 dev_cdc_vcom_lite_bm demo with IAR.

The default demo use FS USB0 as composite VCOM. In order to change to HS USB1, I modify USB config setting as below:

rebuild the project and download. USB1 can be recognized as two VCOMs.

See my attached testing video.

Have a great day,
Jun Zhang

Hi Jennie,

if you refer to my original post - i describe doing just that, but i am unable to connect still. i have now tried multiple different projects in the sdk download, and nothing improves the situation.

thank you

In your previous email, you said you were not able to build. If you can make the project pass build. please follow the video to pass build first.

If build successfully, make sure you choose the correct debugger driver. For example, I use CMSIS DAP interface, I set driver as CMSIS DAP.

Have a great day,
Jun Zhang

hello zhang,

thank you for your help. i am able to build and have the demo running. i would like to combine now the "hello world" example with the virtual com example, since hello world has the printf working with the debug console. unfortunately, i'm not see a straighforward way to do this. i have found 2 different threads ( https://community.nxp.com/thread/458760 and How to use CDC VCOM example with printf? ) but they are not quite the same since they are referring different line of microcontrollers, and as the latest version is 2.6.

Hi Eileen.

Good to know your previous issue has been solved.

I am on leave this week.

I believe this combination issue is a new question, so I suggest you create a new thread for it.

Thus our other support could be able to see it. Thanks for your understanding.

Have a great day,
Jun Zhang
