I got similar error when running a custom Linux distro on LS1043ARDB. I solved the issue by increasing the RAM block device size setup in the kernel configuration: CONFIG_BLK_DEV_RAM_SIZE

Hello shunping lin,

Please add bootargs "ramdisk_size=10000000".

Have a great day,
TIC

Hello,

I have the same issue but increasing the ramdisk_size did not helped. For me it appeared once I changed the load/entry addresses for kernel and ramdisk in the device tree.

Before it was 0x10008000/0x18000000, now is 0x20008000/0x28000000. RAM is 1G.

Any other suggestions please?

Thanks,

Mihaita
