Hello,

Could you please share more information, for example how are you trying to flash the eMMC?

I suppose that you're trying to flash Linux, could you share the version as well?

Also, I couldn't see that well the dip switch value from the image you have shared, if possible write the value of the SW1101 & SW1102.

Best regards,
Aldo.

Hi,

Thank you for sharing more information, everything looks correct, the only thing that I would like you to share more in detail is how are you flashing the image.

For an example on how to flash an i.MX8MM EVK you may refer to the following document:

Hello, 

I am using the uuu tool to flash, but the issue i am facing is, its is not detecting the download USB type C port. Normally when you put in program mode it should detect the NXP semiconductor but now the Port is not getting detected,  I am getting the below massage when i do dmesg command in terminal.

What might be the issue
