Mfgtool warp7 USB not renumerating after initramfs load

Hello,

I have an imx7s warp7 that is not renumerating midway through updating the board's image using mfgtool.

When mfgtool loads a new image it loads up uboot, initramsfs and UTP creating a mass-storage gadget, after which it should renumerate and continue loading the real image, fs etc.

The problem I'm experiencing is that the warp7 hangs once the UTP mass-storage device has been created. The only way to proceed with loading the second half of mfgtools's transfer is to quickly pull out the usb lead and reinsert. This causes windows to detect the new mass-storage device and mfgtool carries on to complete is overall job. In production this need to be automatic as it should be.  

 

Any advice would be appreciated.

Hi Edward

for warp7 may be useful to check

git.denx.de Git - u-boot/u-boot-imx.git/blob - board/warp7/README 

as for mfg tool, please check usb id signal, it should be high or float.

Warp7 as other third party boards is not supported by MfgTools as mentioned on
https://community.nxp.com/thread/440764
one can try to add such support using attached document and Yocto Guide
sect.6.2 Manufacturing Tool.

Best regards
igor
