After building the upstream u-boot for mt7621 there are u-boot-dtb.img, u-boot-dtb.img and u-boot-lzma.img. Some of them can be started using bootm but I forgot which one it is. You can't test u-boot-spl from memory though, because you can't initialize ram when the code itself is in ram. -- Regards, Chuanhong Guo ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

Probably most of it is the same on MIPS-based targets: https://lunarius.fe80.eu/blog/openwrt-u-boot-boot-u-boot.html > > This is the only meaningful documentation I have found. > > https://u-boot.readthedocs.io/en/latest/board/mediatek/mt7621.html > > Thanks! > > > ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

We have a possible need to modify our vendor (or vendor's vendor, hard to be sure) U-Boot. On our MT7621 boards we have vendor versions 2.0.0 aka Ralink version 2.0.0 and 1.1.3 aka Ralink version 4.3.0.0. And I have the Mediatek SDK with source for what claims to be version 5.0.0.0. Attempts to clarify with the vendor what's going on or get exact sources or history have proven challenging due to timezones and language barriers, and I think they simply may not know. Obviously using the OpenWrt version is going to be probably more satisfactory, although there may well be vendor changes to support MCU etc. It's been many many years since I did u-boot work, but is there some magic to load u-boot image into RAM on mt7621 and run it to try it out before flashing? I know there are configuration options for DDR and CPU frequency, etc, but tftping the u-boot binaries variously and using 'go' result in an apparently stopped system. This is the only meaningful documentation I have found. https://u-boot.readthedocs.io/en/latest/board/mediatek/mt7621.html Thanks! ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel

Daniel Golle [2022-11-17 17:01:43]: Hi, > Add swig/host to build dependencies. this doesn't looks like a cleanup as commit subject suggests, but rather contrary :-) Anyway, IIRC we've added swig as a "soft host" requirement on buildbots after this mail[2], so perhaps we should revisit that now and make it a hard host build prereq instead? Something like we do for `mkisofs` in target/linux/x86/Makefile? Otherwise it looks like we would need to move swig from packages feed into main repository and I'm not sure if we really want to do that. 1. https://git.openwrt.org/3776a9157532e694 2. http://lists.openwrt.org/pipermail/openwrt-devel/2021-January/033605.html Cheers, Petr ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
