Catalyst 9300 cannot copy file form usb

[kostasthedelegate]

Hello, 

I have a catalyst 9300. I erased the ios image (factory-reset all) and now it loads in rommon

I connected a USB to try to copy the image file but I get the following 

switch: copy usbflash0:cat9k_iosxe.16.09.04.SPA.bin flash:
Write access to "flash:" unsupported.
Unsupported destination device/filesystem.

Why it flash cannot be written?

Any ideas?

Thanks and regards, 

Konstantinos

Hi,

Can you try the emergency install as documented here?

Hello, 

Thank you for your answer!

I have tried it but it fails to complete. 

The solution to my case was to boot the IOS from the USB and then to copy the bin file to the flash. 

Then I booted from the flash and all is OK!

So finally what was the solution ? if i try to read from USB it says "file system protocol not found on device" followed

by "failed to read contents of usbflash0:"

I have quite a few 9300 series in my company that all need to be resetted to factory default...

Thnx,

Lander

Hello @landergustin27534 

Have you tried changing the Filesystem structure of the usb

Maybe make it fat or fat32

Hi

Make sure that the usb Drive is in MBR Partition style.rommon cant browse GPT Partition style drive.
