I am still not able to upgrade imx28 using my own upgrader.It seems it hangs at the fsg_main_thread().Did anyone faced similar kind of problem ?

Hi Arjun,

We are facing similar issue when trying to  run the MFG tool in front of our custom board. We have a NULL pointer exception in do_scsi_command of file storage gadget.

There is probably something we miss?

Did you manage to solve your issue ? how?

thanks

Thomas

mfg tool uses ramfs. You can't put rootfs on target media when run updater.sb or updater_ivt.sb.
