Hi all, I'm working on a project utilizing a Realtek RTS3916N mips SoC and as part of Realtek's bsp offering, they provide their own fork of buildroot packaged with their prebuilt binary toolchain. I would much rather use yocto instead however Realtek made it clear that no yocto support is available from their end and they have no plans to provide it in the future.
In theory, I have Realtek's u-boot and kernel source so it should be possible to build an image so long as poky is instructed to use an external toolchain. This is where I hit my first road block because Realtek only supports uClibc and I know the yocto community moved way from uClibc, in favor of musl, since the Morty release. As a result, I decided to use Krogoth-15.0.0 (knowing it's EOL) only because it supports uClibc. Now that I had picked a specific version of poky, I continued forward with the EXTERNAL_TOOLCHAIN feature. The documentation references the meta-sourcery layer as the typical use case. Using a sourcery toolchain tarball ( 2014.05) I was able to build qemuarm/glibc therefore as far as I can tell the EXTERNAL_TOOLCHAIN feature works as documented. Unfortunately, the issue I have now arises when I use the Realtek toolchain. meta-sourcery informs me that building against uClibc is not allowed as it has been blacklisted. Only glibc appears to be supported. I have looked around to see what other projects are similar and the closest I can find is the creator CI20 however due to the Realtek toolchain being based on uClibc, I haven't been able to find anything suitable for my usecase. I would greatly appreciate any suggestions regarding how to proceed forward with yocto integration, using a mips uClibc based toolchain. Is there any other course of action that I can try? Thank you, Davis
