Hello, Nikolay

Now I see, what you mean.

 From every dump the requests made by U-Boot are the same. They're as follows:
00:00:00.000310 IP (tos 0x0, ttl 255, id 11267, offset 0, flags [DF], proto UDP (17), 
length 66)
     192.168.100.88.3821 > 192.168.100.254.69:  38 RRQ "uImage" octet timeout 5 blksize 1468

However the answers from servers are different.
Linux host answers with 516 byte packets for example:
00:00:00.004169 IP (tos 0x0, ttl 64, id 29290, offset 0, flags [DF], proto UDP (17), 
length 544)
     192.168.100.254.56334 > 192.168.100.88.3821:  516 DATA block 1
Whereas Windows host answers conforming to requested block size somewhat:
00:00:00.000136 IP (tos 0x0, ttl 128, id 20143, offset 0, flags [none], proto UDP (17), 
length 1500)
     192.168.100.86.63959 > 192.168.100.88.3811:  1472 DATA block 1

Also those configs, which contain "#define CONFIG_TFTP_BLOCKSIZE 4096", are from 
completely different boards. As well as neither did I nor it was by default defined for 
mine board.
So I believe that there must be something different with my set up. I have not yet tried 
debugging network at U-Boot side, but it is the last thing, that left to check.

But anyway thank you for your insight for large packets and U-Boot.

Best regards
