Hi Alfonso,

Maybe, you miss following steps mentioned in the guide: https://projectacrn.github.io/latest/tutorials/using_ubuntu_as_sos.html

 


Thanks all, yes, that was the problem. I can finally launch the RT kernel! I had skipped the "Prepare the User OS (UOS)" section (I wanted to try the RT kernel instead), and had not noticed that bit.

Do you know which version Alfonso should use? I believe it is 20191018 but it would be appreciated if you could confirm.

 

@Alfonso, if true, you can install it as follows $ sudo apt update $ sudo apt install m4 bison flex zlib1g-dev $ cd ~ $ wget https://acpica.org/sites/acpica/files/acpica-unix-20191018.tar.gz

$ tar zxvf acpica-unix-20191018.tar.gz

$ cd acpica-unix-20191018

$ make clean && make iasl

$ sudo cp ./generate/unix/bin/iasl /usr/sbin/

 

Thanks,

Geoffroy
