free space chaos calmer 15.05.1

[davidedp]

I have just updated the firmware of my rt5350f to the last release of chaos calmer
https://downloads.openwrt.org/chaos_calmer/15.05.1/ramips/rt305x/openwrt-15.05.1-ramips-rt305x-olinuxino-rt5350f-squashfs-sysupgrade.bin
After having finished the installation via tftp I noticed that the free space is now just 232 KB, while it was 2 MB with the previous version. Is there any module or packet that has been added and that I can remove. Do you think I did something wrong?

On the current version of chaos calmer 15.05.1 when I type df -h I obtain:

root@OpenWrt:~# df -h
Filesystem Size Used Available Use% Mounted on
rootfs 448.0K 216.0K 232.0K 48% /
/dev/root 2.3M 2.3M 0 100% /rom
tmpfs 14.2M 624.0K 13.6M 4% /tmp
tmpfs 14.2M 48.0K 14.2M 0% /tmp/root
tmpfs 512.0K 0 512.0K 0% /dev

overlayfs:/overlay 448.0K 216.0K 232.0K 48% /

On the previous version instead:

root@OpenWrt:/# df -h
Filesystem Size Used Available Use% Mounted on
rootfs 4.2M 2.1M 2.1M 50% /
/dev/root 2.5M 2.5M 0 100% /rom

The partition size in the latest version of this trunk is incorrect.

Check the 2 dts files.
target/linux/ramips/dts/OLINUXINO-RT5350F.dts and OLINUXINO-RT5350F-EVB.dts

And edit the next line.

Code Select Expand

                          partition@50000 {
                                        label = "firmware";
                                        reg = <0x50000 0x3b0000>;
                                };


and change it into

Code Select Expand

                          partition@50000 {
                                        label = "firmware";
                                        reg = <0x50000 0x7b0000>;
                                };

Am I supposed to recompile the kernel or I can change only the device tree blob?

After editing the .dts files you have to run make again.
If the kernel is already build it will only regenerate the .dtb files and recreate the sysupgrade package.
