Title: Incorrect system mount
I try to get builds with linux kernel 5.10 and 5.18 (mainline) for my board with RK3399.
But I see that OS after boot this builds has incorrect memory size, root partition is only 1.2 GB and all other 28 GB doesn't mount to any point.
Here is df and fdisk command for current 5.10 kernel build:

  2. firefly@firefly:~$ df -h
  3. Filesystem      Size  Used Avail Use% Mounted on
  4. /dev/root       1.2G  917M  218M  81% /

Copy the code


In builds with original firefly kernel 4.19 I have correct memory mounts:

  2. firefly@firefly:~$ df -h
  3. Filesystem      Size  Used Avail Use% Mounted on
  4. udev            1.9G  8.0K  1.9G   1% /dev
  5. tmpfs           384M  1.5M  383M   1% /run
  6. /dev/mmcblk2p7  1.2G  884M  203M  82% /root-ro
  7. /dev/mmcblk2p8   28G   61M   28G   1% /userdata
  8. overlayroot      28G   61M   28G   1% /
  9. tmpfs           1.9G     0  1.9G   0% /dev/shm
  10. tmpfs           5.0M  4.0K  5.0M   1% /run/lock
  11. tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
  12. tmpfs           384M     0  384M   0% /run/user/0
  13. tmpfs           384M     0  384M   0% /run/user/1000
Copy the code


What should I check and change that to get correct auto mounts?

I experiment with parameter.txt values. In logs above parameter for 5.10 (and 5.18) was:
  1. CMDLINE: mtdparts=rk29xxnand:0x00002000@0x00004000(uboot),0x00002000@0x00006000(trust),0x00002000@0x00008000(misc),0x00020000@0x0000a000(boot),0x00010000@0x0002a000(recovery),0x00010000@0x0003a000(oem),0x00010000@0x0004a000(backup),0x289c00@0x0005a000(rootfs),-@0x2e3c00(userdata:grow)
Copy the code


For 4.19:
  1. CMDLINE: mtdparts=rk29xxnand:0x00002000@0x00004000(uboot),0x00002000@0x00006000(trust),0x00002000@0x00008000(misc),0x00020000@0x0000a000(boot),0x00010000@0x0002a000(recovery),0x00010000@0x0003a000(backup),0x289c00@0x0005a000(rootfs),-@0x2e3c00(userdata:grow)
Copy the code


If anything, in 5.10 builds i get incorrect mounts with 4.19 parameter.txt settings.

I get worked build with stable 5.18 kernel of Linux. I just forgot copy compiled ramdisk.img from Firefly kernel 4.19 build.
