Hello everyone!
I am trying to port lede to the Fritzbox 7490 which uses a similar chipset than the already supported 7360 SL.
Currently i am trying to the the serial console running and building an image.
I read that the adam2 bootloader supports booting directly from ram. see https://wiki.openwrt.org/doc/techref/bootloader/adam2
Anybody else working to get the device up and running?
Does anybody have experiences in booting from ram using adam2 (possible bricks,....)?
thx
Hi, did you get the device working with lede or openwrt?
Best Regards
Hi.
No, i stopped working on it because it is my production device 
I am now using freetz to customize the device.
Best regards
Hey, is this device supported yet?
https://forum.openwrt.org/t/support-fritzbox-7490/4112
This guy says it is using the same chipset as the 7360 sl?!
Thanks!
Hm.. What was your the problem? Did you build the image for the device?
There is no support for 7490 so far, the SOC and the related 7360 are, which might make adding support reasonably easy (no drivers for DECT though), but someone with the device still has to do the porting.
How to do the porting? I have multiple devices.
If you refer to DECT functionality in particular, the necessary drivers (and subsystem!) will probably have to be developed from scratch, with little to none reference to go by.
I don't need the DECT functionality, I just need the base system, no special features 
Look through the git history for the commits adding support for the 3370 and 7360, the 7490 should be reasonably similar.
from the wiki I cannot understand the status of the OpenWrt support...
is it working?
If the wiki does not explicitly state that it is supported, then it is not.
This still applies:
Hey, if it’s any help I’m willing to sponsor this by donating a 7490. Pm me if your interested.
(I’m also not worried about DECT functionality either)
well, I thought I'd give it a try and see if I could do this myself. Bare with me, as this is the first device I've attempted to add support for.
As a starting point, I am beginning on the excellent work of @danijeltudek (which is still being finalized before merge to master).
I can happily report that the 7362 kernel ramfs booted successfully on my 7490.
The good:
The bad (where I need to focus my efforts)
w list isn't showing any output (not sure if this is normal for a minimal kernel ramfs image)
lspci isn't available. Any suggestions on how to verify devices are detected before I bite the bullet and flash an image? Suggestions on any other useful modules to include in the kernel ramfs image to aid testing/validation?
Very loosely, my plan currently is to:
Any tips or insights on what else to verify/test next would be appreciated.
(and apologies for the somewhat rambling post..)
This is due to no WiFi card connected to the Lantiq chip. The 7490 are in fact two routers on one PCB with a QCA9558 linked to the Lantiq via Ethernet. It handles both WiFi interfaces (the integrated one and a QCA9880.
This might also be the reason for the differing claims of RAM size. You can see the RAM and both CPUs on this picture: https://boxmatrix.info/w/images/4/43/FRITZ!Box_7490-Image37.jpg

Download AVM's kernel source here:
http://osp.avm.de/fritzbox/fritzbox-7490/source-files-FRITZ.Box_7490-07.01.tar.gz
Take a look at my OpenWrt device tree for 7362, compare it to 7360, and compare both to AVM's device trees for HW 183 (7360), 185 (7490) and 203 (7362). You'll find all GPIO pins and their default states there.
Regarding the build process, if you want a clean build, use make clean. It keeps the toolchain. For quick kernel development, use make target/linux/install. Don't forget -jXX option for multithreaded build. I use -j33 on my 32-thread development machine.
Hi, nice to hard!
Is there a git repo for this?
Thanks!
It's in this pull request: https://github.com/openwrt/openwrt/pull/1742
Keep in mind that more work is needed before it'll be accepted, but it can be used as a reference to get 7490 to boot, at least.
Made the first named 7490 image , and device still booted which is good. In my searches, it seems that there is no lspci binary available for openwrt (which has always been my goto for checking hardware). Is doing a diff between the various /proc files the right way to tell whats working and whats not?

Still Todo; Ethernet ports to physical port mappings are still wonky. I did try changing ../../../../target/linux/lantiq/base-files/etc/board.d/02_network and specifying different numbering - but it didn't seem to have any effect.

There should be one in the pciutils package, or find the source package at feeds/packages/utils/pciutils in the OpenWrt tree with the packages feed.
