Hi Matteo,

Which version of U-Boot are you using?

Try setting the following environment variables:

tftpblocksize=512
tftptimeout=10000

Dear All,


I've noticed that when u-boot is downloading

files from a tftp server (e.g. vmlinuz, initrd

etc.) it starts to time out quite heavily

"##T #T #T..." if I simply ping the NIC of

the raspberry 4b on which it's running.


Thanks for any comment or suggestion on this

behavior.
