Omega 2S+ Image Size

matiaslao

Hi @crispyoz, I'm including below the steps followed to setup the build system and compile it. I started from scratch to make sure that the changes pushed by @Lazar-Demin were included in the build system.

Note: I'm using a Linux System and not the Docker image.

create an onion folder, navigate into it and download the build system from github.

mkdir onion
cd onion
git clone https://github.com/OnionIoT/source.git -b openwrt-18.06
cd source

setup the onion feeds.

sh scripts/onion-feed-setup.sh
python scripts/onion-setup-build.py

update the image configuration. If I manually chose the packages and target (among other options), I run make menuconfig. However, I usually use an already generated .config file, which has a diff format.
```
cp CustomConfig /home/user/onion/source/.config
cd /home/user/onion/source
make defconfig
```
finally, the image is built by running make -j4. If any error is raised, I re run the command with the following syntax to get more information about the error: make -j1 V=s

These bullets summarize the steps followed to build the image. Let me know if there is any way I can share with you the config file.

BTW, when selecting both the Omega2 Pro and the Omega2+ as the Target Devices, binary for Omega2+ is generated but not for the Omega2 Pro. As for the Omega2+, the binary size is 18 MB, and as for the Omega2 Pro, I get the warning message that the image is too big.

Best regards,
Matias

@matiaslao You can paste the CustomConfig to https://paste.mozilla.org/

@crispyoz please find the CustomConfig in the following link. https://paste.mozilla.org/qrMwjsZR

@matiaslao I built your firmware from scratch using your config file and it completed fine. Have you checked the updated is in place? It's in source/target/linux/ramips/dts/OMEGA2PRO.dts

matiaslao

@crispyoz good to know that it worked for you.

I've checked the source/target/linux/ramips/dts/OMEGA2PRO.dts and it includes the latest modification pushed by @Lazar-Demin to the source repo.

/dts-v1/;

#include "OMEGA2.dtsi"

/ {
        model = "Onion Omega2 Pro";

        memory@0 {
                device_type = "memory";
                reg = <0x0 0x8000000>;
        };

        new-leds {
                compatible = "gpio-leds";

                wifi {
                        label = "omega2pro:blue:wifi";
                        gpios = <&gpio1 12 GPIO_ACTIVE_LOW>;
                };
        };
};

&firmware {
        reg = <0x50000 0x1f30000>;
};

&system_led {
        label = "omega2pro:amber:system";
        gpios = <&gpio1 11 GPIO_ACTIVE_LOW>;
};

&pinctrl {
        state_default: pinctrl0 {
                uart2 {
                        ralink,group = "uart2";
                        ralink,function = "gpio";
                };
        };
};

BTW, I'm sharing with you the content from source/bin/targets/ramips/mt76x8 directory. Does the Omega2+ image build has the same size than the one you built?

user@ML-PC:~/onion/source/bin/targets/ramips/mt76x8$ ls -lh

Thanks for the support being provided.

Best regards,

@matiaslao I think I have managed to duplicate your problem, it's not generating the openwrt-ramips-mt76x8-omega2pro-squashfs-sysupgrade.bin firmware. No error but I only have the issue when using your config. Don't have a lot of time right now but but will try to nail down the cause.

@crispyoz thanks for the update. You're correct. The make command does not return an error. However, after it finishes running openwrt-ramips-mt76x8-omega2p-squashfs-sysupgrade.bin is generated but not openwrt-ramips-mt76x8-omega2pro-squashfs-sysupgrade.bin.
When looking into the make command output, the messages shown below are the only reference to the Omega2Pro image.

WARNING: Image file /home/user/onion/source/build_dir/target-mipsel_24kc_musl/linux-ramips_mt76x8/tmp/openwrt-ramips-mt76x8-omega2pro-squashfs-sysupgrade.bin is too big

Please let me know if you have any new finding.

Thanks in advance,
Matias

Hi @Lazar-Demin & @crispyoz, I was able to find the root cause for this issue. I've created a pull request in OnionIoT/source github repository with the fix.

Lazar Demin

@matiaslao Good find! I've merged in the PR, thanks!

crispyoz

Good catch @matiaslao !
