Linux/PROCESSOR-SDK-AM335X: Cannot build meta-toolchain-arago-tisdk in Arago

Tool/software: Linux

Goodmorning,

after having successfully built the custom-image, following

http://processors.wiki.ti.com/index.php/Sitara_Linux_Training:_Getting_Started_with_Openembedded

I'm trying to build the cross-toolchain but I get the following error.

davide@davide-HP-ProBook-450-G5:~/tisdk/build$ bitbake meta-toolchain-arago-tisdk

Summary: There was 1 WARNING message shown.
Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

The build configuration is processor-sdk-05.01.00.11-config with gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabihf installed in /opt.

In my local.conf I changed the following:

DISTRO_FEATURES_remove = "wayland"

INHERIT += "own-mirrors"
SOURCE_MIRROR_URL = "software-dl.ti.com/.../"

#Used for remove bbappend recipe from different layers
#BBMASK="meta-arago/meta-arago-distro/recipes-core/systemd/systemd_%.bbappend"

What do I need to modify?

Thank you.

Best Regards,

Davide Brunelli
