Before posting this message, be sure I have read and tried all what was found on OpenWRT forums.
I can easily install OpenWRT 18.06 from EdgeOS with "add system image" from a tar file, as shown in many messages, but once the router rebooted under OpenWRT 18.06 I definitely can't sysupgrade to 19.07.2.
I have tried all what was adviced, even downgrading EdgeOS, before installing OpenWRT 18.06, and later sysupgrade to 19.07.2, nothing works.
When doing so, the rooter keeps rebooting.
Any idea why it doesn't work ? Could we have available a working OpenWRT 19.07.2 initram tar file, as I couldn't generate it myself, after numerous tries.
Any configuration within "manuconfig" to enable the generation of such tar file ?
I have read that it was failing because the kernel was too big ?
What should be removed from the kernel then ?
It would be very nice to have one available on OpenWRT EdgeRouter X device page, so that we can later on sysupgrade with the full OpenWRT 19.07.2 bin files , and those I found with luci already installed ?
Kind regards for your help, because currently, I am definitely blocked with version 18.06.
