do you get the sources , Would you mind to send me a note, when you got the sources?

Nope, still waiting. I think @JakubVanek hasn't had any luck either.

Yep, I tried to obtain the source code for 1.10E firmware version in March 2020, but I wasn't successful with that. Some older kernel/u-boot revisions are available in the extended repository though, and I believe the EV3os.tar.bz2 archive mentioned in #42 is present in the latest 1.09 sources as the file open_first/lmsfs_with_telnet.tar.bz2. Nevermind, EV3os.tar.bz2 should have contained the updated source code of kernel and u-boot, this is not available anywhere AFAIK.

Hi, any update on this? I’ve made 2 kernel modules (from different sources) for Edimax Un7811 v2 (which is not supported by original firmwares), but it’s builded for the old 1.04/1.05 firmware. So, I’m not sure that it will work on the latest 1.09H/1.10E (will test later). BTW looks like 1.09H and 1.10E have minimal differences: the first is for Home Edition (31313 set) and the second for Education (45544 set).

Hi, I unfortunately do not remember LEGO giving me any feedback apart from that they were aware of the issue. However, I wouldn't rule out that some update got lost in my inbox, so I don't really know what is the current status of this.

Hi, thanks. Then I’ll try to compile the latest source code using the old kernel we have.
Uboot tools, mkimage etc are installed separately, so I think only the kernel can affect the building process. Diff shouldn’t be too large between 1.09 and 1.05 which we have.

Well, I've made some tests: it fails to build but overall looks not bad :D
v109D uses the same kernel & uboot versions as v105D (at least it stated in build files).
Errors when building the kernel:
