Hi there,
I would like to disable CONFIG_SERIAL_8250
in the kernel. But once it is disabled the sysupgrade stops working.
I came across https://openwrt.org/docs/guide-user/additional-software/saving_space, where it mentions that by disabling the kernel setting: This will also save RAM by preventing /sbin/askfirst from running. However, this will break sysupgrade.
But it doesn't explain why it brakes sysupgrade. Is there a way to disable the kernel setting and have working sysupgrade?
Cheers,
Andy
