I´m using my self built image on Bananapi R3.
Today I ran the make process again
I had trouble with fitblk (error 2, missing files somewhere), so I needed to delete ./feeds/packages/utils/fitblk/
After this the build process compiled my image and I could upload the sysupgrade. I was surprised, as LuCi reports about incompatible image.
I´m able to update without keeping config, but I´m concerned about "Force upgrade". Is it safe to continue with this button checked?
make menuconfig shows the correct target system/subtarget also as profile.
So I´m sure, the image is correct. I´m only fear about the "force upgrade" switch, I thought deactivating the other checkbox would be enough.
The image contains openvpn, samba4 and minidlna. This could explain the size.
I´m booting from emmc and the sysupgrade will be written to emmc. NAND memory is not involved in my setup. But the message contains some about bootloader, this was my concern.
And no, the hardware board revision will not change by itself. As far as I know, board version 1.2 isn´t available on the market.
Anyway, I have checked the box "Force upgrade" and all went fine. Because I have included my config in my build, I didn´t have additional efforts to restore the settings.
