  @Nagarjuna-Reddy I can't test this right now, but first I think you need to remove the sdcard module as it will likely be managing the registers: rmmod mtk_sd Then I expect you can use the GPIO like so: gpioctl dirout-high 22 gpioctl get 22 gpioctl dirout-low 22 gpioctl get 22 cat /sys/class/gpio/gpio22/value

  @jonty So your server is now bound correctly, so now look at the client. Did you update the client code to use the specific port 9090? lsof is not installed by default, you need to install it: opkg install lsof If this fails then you need to update your distfeeds. Edit /etc/opkg/distfeeds.conf uncomment lines 2 and 5. Run opkg update; opkg install lsof But since your server will now bind correctly you don't need lsof

  @Koos-du-Preez If you have a lot of packages to update maybe you should be use oupgrade to ensure you are on the latest build.

  @Andriy-Malyshenko You can download OpenWrt 19.07.5 from the OpenWrt site: https://downloads.openwrt.org/releases/19.07.5/targets/ramips/mt76x8/openwrt-19.07.5-ramips-mt76x8-omega2p-squashfs-sysupgrade.bin You don't get some of the Onion developed components but you can always install those yourself.

  @column-column OpenWrt doesn't have man pages nor a man command. The maintainers have not created man pages for the platform.

  @slx Take a look at the OpenWrt documentation on how to add feeds to your build system. You may run into issues with dependencies however. https://openwrt.org/docs/guide-developer/helloworld/chapter4

  @Alberto-Brosich This is a nice article on debugging wifi issues: https://community.onion.io/topic/3306/faq-how-do-i-check-if-i-m-successfully-connected-to-a-wifi-network/5?_=1610027797289 The log should give you more information about what is going on. If you are associated but not getting an IP it may be an issue with your dhcp client, to confirm this set the proto to static and hard code the ip. After restarting the network see if you can ping your network router and 8.8.8.8 (google dns) The results of this will provide more info as to where your issue may lie.

  @MickPF This depends on how you are doing your development. New players often start off doing some development on their Omega2x device, eventually, you realise this a short term solution since IoT devices are by design resource poor. The best way to do Omega2x development is to install the build system https://github.com/OnionIoT/source then you will have access to everything you need as well as the cross compiler, so you can use your more powerful desktop/notebook device for your development and then move the completed work to your Omega via scp/ftp. The headers and libraries you are looking for are on the Onion Github, https://github.com/OnionIoT Also refer to the docs on how to compile on the Omega: https://docs.onion.io/omega2-docs/i2c-c-library.html
