Incorrect system mount

Gustoff

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:

1. 
   
2. firefly@firefly:~$ df -h

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

1. 
   
2. firefly@firefly:~$ df -h
   
3. Filesystem      Size  Used Avail Use% Mounted on
   
4. udev            1.9G  8.0K  1.9G   1% /dev

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.
