seems like strings breaks my (older 2014-04) uboot:
BPI-IoT> tftp ${loadaddr} 192.168.0.10:files.lst
Using mtk_eth device
TFTP from server 192.168.0.10; our IP address is 192.168.0.11
Filename 'files.lst'.
Load address: 0x84000000
Loading: #
43 KiB/s
done
Bytes transferred = 89 (59 hex)
BPI-IoT> echo ${filesize}
59
BPI-IoT> strings ${loadaddr} ${filesize}
lߟA�����������������c���_���=�������������w������ �{ߟ��wo�W �������������y�_
BPI-IoT> Minicom2.7Minicom2.7�߅_k�|UZ���߿����������0� ������Ż��{������� �
also tested with bytecount 20 instead of filesize-var, same result
cannot use here new uboot till ethernet-driver is not ready
