Hi,

 

We are getting the following issue while trying load the image from ram. I have checked the disk image and have found the file "init" in "/sbin". I have checked that the permissions are set to allow execution. I have also checked that busybox is present in /bin and that the permissions are set to allow execution.

setenv bootcmd 'bootm 0x42000000 0x42300000' ; setenv bootargs noinitrd console=ttyAM0,115200 root=/dev/ram init=/sbin/init rootfstype=ramdisk rw ramdisk_size=10000; boot

But we were able to load the rootfs from nand with the following bootargs: setenv bootcmd 'bootm 0x42000000' ; setenv bootargs noinitrd console=ttyAM0,115200 ubi.mtd=4 root=ubi0:rootfs rootfstype=ubifs ro gpmi; boot

 

 

Any suggestions would be really appreciated.

 

 

 

Thanks & Regards,
