Subject: tools: kwboot: Show 'E' in progress output when error occurs
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=5d8aa4c92b86dcdbdb7c9fcf12e6c93c87e16555;p=u-boot.git

tools: kwboot: Show 'E' in progress output when error occurs

When kwboot is unable to resend current xmodem packet, show an 'E' in the
progress output instead of a '+'. This allows to distinguish between the
state when kwboot is retrying sending the packet and when retry is not
possible.
