ICX7150 Switch Upgrade issue - tftp out of buffer space error

[ADIT]

Hi Team,

we are facing an issue with ICX7150 switch upgrade. After clicking the "Copy from Server to Flash" option, it is showing the error "TFTP out of buffer space error". We have files in flash. The switch boot sequence is from Secondary. How to get rid of this error. Any possibility to free up space in flash.

is it a solution to erase files in Primary or do you have any other recommendation ?

Please help on this.

Thanks & Regards
