Hmm... I don't know how I've missed that, since I've been doing that around same time. Issue then was that OpenWrt didn't publish separate toolchain archive, so workaround was downloading SDK and extracting toolchain and dt-bindings from it. Now the toolchain archives are provided, so if the images that need some kind of wrapping, download and extract toolchain into appropriate dir and You're able to rebuild firmware. Some of use cases require building additional packages not present in official repo but that can be achieved with SDK and later providing that package to IB (ImageBuilder). > Do you have some real world example using this rebuild option? This is not exactly what is written this rebuild option does, but I patch IB and use SDK to build 24.10 firmware for Dell ACi for which patches [5] and [6] are sitting in queue waiting for inclusion. Another case would be simple enable of USB ports like in this topic [7]. Or enabling of SPI flash memory on my OrangePi Zero. Or removing console on my Dell ACi to attach RS485 converter. Along the way there were also requests from users which replaced RAM chips or SPI flash with bigger ones. With new enough bootloader one can patch the DTB from there but not every target has it. All of it can be done in fraction of time with benefit of compatibility with official packages repository. > [1]: https://lists.openwrt.org/pipermail/openwrt-devel/2021-March/034239.html > [2]: https://github.com/jwmullally/openwrt_wpa8630p_v2_fullmem > [3]: https://github.com/jwmullally/openwrt_wpa8630pv2_patched_firmware > [4]: https://github.com/xabolcs/openwrt_hootoo_ht-tm02_oldstable 5. https://patchwork.ozlabs.org/project/openwrt/patch/20250202151028.84276-1-tmn...@terefe.re 6. https://patchwork.ozlabs.org/project/openwrt/patch/20250202151028.84276-2-tmn...@terefe.re 7. https://forum.openwrt.org/t/nanopi-neo-enable-usb1-riser-cards/230948/1 > Thanks, > Szabolcs Regards -- TMN _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
