We are using this:

 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
Check SDRAM ...
A0000000
A0000400
Check SDRAM pass!
 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

host:
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&6
Now checking whether all configure args valid: YES
Current device information:
CPU type is Ingenic XBurst Jz4740
Crystal work at 12MHz, the CCLK up to 252MHz and PMH_CLK up to 84MHz
SDRAM Total size is 32 MB, work in 4 bank and 16 bit mode
Nand page size 2048, ECC offset in OOB 6, bad block offset in OOB 0, bad
block page 127, use 1 plane mode
 Execute command: memtest 0 0 1024
 CPU data: JZ4740V1
 Now test memory from 0x0 to 0x400:
 Download stage 1 program and execute at 0x80002000
 CPU data: JZ4740V1
 Test memory pass!

in our 4720 it will output
