Error: Failed to download image - tftp: write error



 
Environment
EXOS All
Cause
There may be files in /usr/local/tmp that need to be deleted. The download image script uses this directory as a scratch directory, and if there is not enough free space, the download may fail.
Resolution
Check ls /usr/local/tmp to ensure that there are no files present. If there are, they can be deleted with the rm command. rm /usr/local/tmp/* will delete all files from this directory.

This error can also happen when trying to install a full summit image on switches that can only use the summitlite image.

If there are no files present and the upgrade still fails, try upgrading the switch from the bootrom. Please refer the link below for the steps.
How to upgrade BootROM on a Summit switch

If it still fails, please contact GTAC.
Additional notes
Prior to EXOS 15.5, /usr/local/tmp was referred to as internal-memory.

If there are no files in /usr/local/tmp, the image may not be supported on this switch. See TFTP Write error when attempting Firmware update
