Hi one of our C836 does not allow a

C836#reload at 20:00

No bootable image in flash. Load an image into flash and try again; eg. using "copy tftp://<server>/<file> flash:"

Reload to ROM disallowed from a telnet line. Reload cancelled.

though a image is in flash:

You can also see that the box booted from this image

Any idea about the reason ??

On 801 or 803-routers I had always seen a TinyRom-image in the flash, I do not so on the 836. does this box also need this TinyRom ??




Re: C836 does not allow "reload at"

You may need to add a boot system statement in order to reload via telnet. The global config command is

boot system flash flash:c836-k9o3s8y6-mz.123-4.T3.bin

Make sure that's the only boot system statement.

Then write mem and try the "reload at" again.
