Dear Openwrt users and devs,
Im trying to build a custom image (ext4) with /dev/mem enabled and optimalisation tags, for a couple of days now.
Everything works with the normal pre-generatred combined.ext4.img but the problem start if I build the 21-02-3 software with the generic or 64 target config.
Wget ...../targets/21.02.3/targets/x86/generic/...../build.config -O .config
Even if I don't change anything else and flash the image I only can reach the device trough serial, it won't recognize the lan cable.
The network options and DHCP are good, I learned from that.
But if I flash the original x86/64 ..... Combined-ext4.img and I plug in a lan cable, some message shows up and tries to connect. Like eth0 .... Up-link:connected.
But if I use the own build image and plug a lan cable in, nothing will show up. When I use
Opkg listevery single package thats inside the /x86/64 build.config on y is shows up. So I don't know anymore where to look.
I tried so far
Multiple times to clean and restart everything, using diff targets from master to v21.02.3. generic or 64. Without succes.
Each build has the same problem.
Now is the idea, to use the pre-generatred .config file set and change everything from the .config file of generic by hand to mach. And use
make defconfig to see if it will take the change. Here I got stuck the config file says:
CONFIG_DEFAULT_TARGET_CPU="pentium4" CONFIG_TARGET_OPTIMALISATION="-O -pipe Intel something something"
And I can't change it, every time I load:
Everything change back, and I don't know what to change to fix that, i know for sure I don't have a pentium4 but a amd gx412tc and 3 times I210at. From the Openwrt device page it says "to further optimize the produced binaries ... ... SET
CONFIG_TARGET_OPTIMIZATION="-Os -pipe -march=btver2"
And if this images doesn't work I probably gonna try to:
Try to create a patch that set the /dev/mem automatically to y, don't even know if that's possible. And try to create a patch that increase automatically the size of the disk online after install.
Try to edit the include/kernel-version.mk to match the newly generated kernel md5 checksum. To use the generated quick image builder. Probably not going to work because somewhere will be a .vermagic file created, and kernel-version.mk doesn't have to do with it.
But if u know why the lan ports (I210xt) won't work with a custom image or know why the cpu target can't change please let me know?
Sorry for my English.
Thanks in advance.
And some afterword:
I just found out that the Openwrt repository easyer can be browsed by using gitk. And wow it's complex and really thanks to all that have some sense what there are doing, and everything they do to make Openwrt great!
I really don't have a clue how everything comes together and works but it's amazing to see and I learn every day something new about Openwrt.
