sftp was used.
Embedded target was rebooted. After reboot the destination was mounted read only.
WIN SCP (on WIN 7 SP1) reconnected successfully but probably didn't recognize the changed write protection.

Thanks for your report.

Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.
