Hi,

We use the MIMX8MM5DVTLZAA chip to carry the circuit design. Now the USB1 interface used to download the image is not recognized. Can you help me?

We are designing with reference to the USB2 circuit of the 8MMINILPD4-EVK development board. The following figure has additional circuit diagrams alarge.pngUSB不识别.PNGnd unidentified signs. and the PIN of USB1_ID is NC.

Hi igor

Thank you very much for your reply.

I checked my circuit and think it is ok.

My board only has emmc boot, and there is no emmc card slot, so I have no way to download the boot image to emmc in advance.

Do you have other ways to help me?

In addition, I use the USB-type-C interface, is it a type-c problem?

Looking forward to your help.

 

Best regards
