[U-Boot] list files on tftp / large kernel-image

[Frank Wunderlich]

Hi,

is it possible to list files on tftp so i can write a script to let user select kernel-image to load?

have anybody tried to load a kernelimage larger than 20MB?

i use dnsmasq as tftp and uboot 2014-version (because 2018-11 für mt7623 currently has no ethernetdriver). 
If kernelimage is larger than ~20MB loading file hangs...tried setting blocksize, but it's the same behaviour, only more/less #-symbols. I don't know how much data is loaded, because there is loadedbytes-counter (i only can count the # and multiply with blocksize if i know it). do i have any chance to debug that or is this already known/fixed?

regards Frank
