Hi Harm,
thanks for the suggestion.
I have this set in my .config file
for the compilation of u-boot:
CONFIG_TFTP_BLOCKSIZE=1468
CONFIG_TFTP_WINDOWSIZE=1
I'm also using a custom boot.cmd file... should I instead just put your vars in it like this:
tftpblocksize=512 tftptimeout=10000
or like this:
setenv tftpblocksize 512 setenv tftptimeout 10000
?
I'm still new to u-boot even though I could make it do exactly what I needed... extremely useful to boot my cluster of raspberry pis 4 b with individual kernel options each.
PS:
Any good book around on u-boot?
Good doc seems so difficult to get.
Thank you!

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.
