I looked to the pictures you have posted, so the kernels are uploaded and you choose the right command
Why did you set nas ip to 192.168.221.6 ?
The ping answer you receive at some moments is that when u-boot is active or after the kernel has been started ?? or does the ping dies after the kernel is loaded ?
After loading the nas gets an IP assigned by your dhcp server so necessary the same one as you use in fvdw-sl-console.
Did you try the fvdw-sl-assistant to find the nas ?
And it seems I made a mistake when making kernel 7. (It is same as 6)
Can you try this updated version #7-2
--edit oops another error I think, this should be the right one
and this one #x
