is there a example about how to call sysupgrade -c bash cmd in C language to start system upgrade?
how to do upgrade in C? I now use system("sysupgrade -c sm.bin"); , but i think it is not very good
Maybe 'system' ?
He just said he used system().
You may be able to use libubus to call sysupgrade via ubus.
root@OpenWrt:~# ubus -v list system
'system' @b5b56299
