What is the addr here the nand offset or the ddr addr? I tried of
doing the same but unable to boot any help?

$ dd if=SPL of=SPL-new bs=512 seek=2
icorem6qdl> tftpboot ${loadaddr} SPL-new
Using FEC device
TFTP from server 192.168.2.96; our IP address is 192.168.2.75
Filename 'SPL-new'.
Load address: 0x12000000
Loading: #######
         1.4 MiB/s
done
Bytes transferred = 32768 (8000 hex)
icorem6qdl> nand bootupdate ${loadaddr} 0x8000
NAND bootupdate successful
icorem6qdl>
