After installing Debian on SD card, it was booting successfully with the ‘run bootcmd’. But when I switched off the power and plugged in again, I was getting the following error messages:

Error! cmd : 8, err : 0201

I found on cyrius.com that I had to give the mmcinit command twice. These are the original setenv commands:

Marvell>> setenv bootargs_console console=ttyS0,115200
Marvell>> setenv bootcmd_mmc 'mmcinit; ext2load mmc 0:1 0x00800000 /uImage; ext2load mmc 0:1 0x01100000 /uInitrd'
Marvell>> setenv bootcmd 'setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm 0x00800000 0x01100000'
Marvell>> saveenv
Marvell>> run bootcmd

To fix the problem, just enter the following setenv commands with the extra (bold) ‘mmcinit;’ :

Marvell>> setenv bootargs_console console=ttyS0,115200
Marvell>> setenv bootcmd_mmc 'mmcinit; mmcinit; ext2load mmc 0:1 0x00800000 /uImage; ext2load mmc 0:1 0x01100000 /uInitrd'
Marvell>> setenv bootcmd 'setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm 0x00800000 0x01100000'
Marvell>> saveenv
Marvell>> run bootcmd

After Debian is booted, halt the system and switch off the power. Now switch on the power and you will see that Debian is booted!
