Copy image files to a OS6850 empty flash

[xys]

Hello,

After some unsuccessful tests in the lab, we cleaned up the entire flash of one OS6850. The only think we have access noe when we boot the switch is the Miniboot:

Code: Select all

[Miniboot]->

if we list the files, it is empty:

Code: Select all

[Miniboot]->llr
-rw       184 Jan  1  1980 boot.params
drw      4096 Aug 30 18:39 certified/
drw      4096 Aug 30 18:39 working/
-rw       184 Jan  1  1980 boot.params.CORRUPTED

Listing Directory certified:

drw      4096 Aug 30 18:39 ./
drw      4096 Jan  1  1970 ../

Listing Directory working:

drw      4096 Aug 30 18:39 ./
drw      4096 Jan  1  1970 ../

        63913984 bytes free
value = 0 = 0x0

How can we copy the necessary image files to the switch? Maybe after mounting the USB drive? How can we do that?

Cheers,
xys
