How does zImage re-enumerate USB as UMS devices during mfg download

Hello,

I have a custom board with i.mx6dp processor, when I use MFG tool to flash the image to emmc, the mfg tool will always stop after jumping to the OS, and seems to be waiting for usb mass storage device to show up, i have to unplug and plug the USB, then the it will find the device and continue the next steps.

I feel that the zImage could not re-enumerate the USB as mass storage device, or at least it could not give proper signal to my PC to notice there is a change happened or  there is a mass storage device appeared.

What could be missing in this process?

 

Thank you!

Have you use the proper image for your board and proper DDR configuration? Many reasons may caused stop after jumping to the OS.
