ZyXELs bootloader supports uimage lzma but only with a kernel size < ~4MB uncompressed or so.. The trick now is to use a uncompressed uimage and let now do jffs2 compress the image, which the bootloader supports. That works, bit is way more unoptimized. This is the reason why we hit that limit earlier here.

What do you propose in these cases? Please help me solve this problem. Or should I just commit a change for the device with a hint in the commit message? Adrian has added a system to block sysupgrade and show a warning message in the commit "build: add DEVICE_COMPAT_VERSION and DEVICE_COMPAT_MESSAGE " 6867d86e085dd4a284c8ee8878839c9e77546f46 see it on Github https://github.com/openwrt/openwrt/commit/6867d86e085dd4a284c8ee8878839c9e77546f46 You can use that to give a warning to users when they try to sysupgrade. -Alberto ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
