[U-Boot] Creating of ramdisk image causes: No space left on device

Hello,

I'm using u-boot for xilinx zcu102. In order to create ramdisk image I used the command: genextfs -d $ROOTFS -b 65536 -D rootfs_devices.tab ramdisk

But during linux boot, linux writes many message: mdev: can't create '....': No space left on device

I tried to use 262144 instead of 65536 and also changed CONFIG_BLK_DEV_RAM_SIZE in kernel configuration to 262144

But the errors were not resolved.

The output of df: Filesystem 1K-blocks Used Available Use% Mounted on /dev/root.old 261919 59492 176213 25% / /tmpfs 2025516 0 2025516 0% /dev/shm tmpfs 2025516 0 2025516 0% /mnt/ramdisk

Can you please help ?

Thank you, Zvika
