USB OTG detection

[Bitesh]

Hi,

     I have built a custom board using i.MX6 solo processor. I want to detect the USB OTG for serial download mode. 

Can you please help to get the board in serial download mode of USB OTG ?

I'm attaching the screen shot of schematic for understanding.

I'll tap the D+ and D- lines of USB OTG ( Ball B6 and A6) and connect to PC Will PC detect the processor ?

Is it ok if I leave USB_OTG_CHD_B and USB_OTG_ID floating ? I think just I need to tap D+ and D- lines and I'm good to go. Please correct me if I'm wrong.

Thanks in advance.

Regards,

Bitesh

Hi @Bitesh,

I hope you are doing well.

[NXP]: Yes, your understanding is correct. USB_OTG_CHD_B and USB_OTG_ID can be left while entering into the USB Serial Downloader mode.

Thanks & Regards,
