Regarding providing a bare-metal toolchain on toolchains.bootlin.com, we have a chicken-and-egg problem: the toolchains on toolchains.bootlin.com are built using... Buildroot. So if we want toolchains.bootlin.com to offer pre-built bare-metal toolchains, we need Buildroot to be able to generate such bare-metal toolchains in the first place :-) Thomas -- Thomas Petazzoni, co-owner and CEO, Bootlin Embedded Linux and Kernel engineering and training https://bootlin.com _______________________________________________ buildroot mailing list buildroot@buildroot.org https://lists.buildroot.org/mailman/listinfo/buildroot
