It's not actually proper OpenWRT. The official GL.iNet Firmware is based on Qualcomm SDK (QSDK) which is supposedly based on OpenWRT 15.05 (very old) plus Qualcomm's closed-source binary drivers (especially WiFi drivers).
Disclaimer: I am NOT an OpenWRT Developer and I am NOT an employee of GL.iNet. All the info I have mentioned here is based on what I gathered by asking and searching in GL.iNet forum.
thanks, now I have serial access to the modem
I did not tried this connector before because I was
affraid of blowing up my modem. The connector on
the e7350 is has you said gnd-nc-rx-tx... and voltage level at 3.3Volts.
I did compile your version of openwrt and tried u-boot tftp load image on it
but I is not finding the rootfs partition.
I checked out branch 73 - the one with WIP for e7350
git status: Your branch is up to date with 'origin/73'
is this the last version you have ? when I check out the master
there is no code for e7350
All ok now, in u-boot, I was doing 'load image' instead of 'update firmware'
now I have good starting point for openwrt.
To revert to original firmware just need to select 'update firmware code pattern' in the u-boot menu. I guess working wifi is still a work in progress.
great job!
Most vendors' stock firmware is built on top of the SDK provided by the chipmaker which is based on some old versions of OpenWrt/LEDE with propietary additions.
It doesn't means that a router can be supported (eg Broadcom or Realtek) but if it's Qualcomm or Mediatek the porting process will be more straightforward unless the vendor enabled secure boot.
I ordered my RT3200-UK into Finland. At that point they did deliver and I didn't have any problems with delivery. Obviously I ran stock firmware for less than two minutes and went for my favorite AP-distro. But I guess something with radio licensing / permites prevent the unit being sold inside EU.
Hardly. That switch can barely run the web interface (compared to a more powerful router, e.v. my Belkin RT3200s), I highly doubt it could effectively act as a firewall/routing gateway for 1Gbps networks, or that it would fix the issues I had with my previous OpenWrt installs.
Now I'm using a Unifi Dream Machine, and it works flawlessly.
