Hi Sean, Thanks for taking a look. I will add the changes you requested. However a test case might be difficult to add in the automated tests. This problem only happens if there is an asynchronous event ( packet received/Button pressed ) which triggers a run_command API call AND when the user has entered some console commands which have enabled the do_repeat flag. If the do_repeat flag is set AND the command issued via the run_command API is a 'non-repeatable' command (e.g mmc write), the command is ignored.

This sets do_repeat flag internally (2) Webserver embedded in main polling loop of uboot detects an image upgrade request (3) Image downloads, about to be written via run_command("mmc write etc.") (4) Since 'mmc write' is a non-repeatable command, issuing it with do_repeat flag set results in command getting ignored (5) Image upgrade fails > --Sean > > > nextin = 0; > > #ifndef __U_BOOT__ > > pi->pgrp = -1; > > > > Regards, Farhan
