Hello,
I am creating a custom nerves system artifact and when I try to use the artifact, the checksum on the file is failing.
Checking for prebuilt Nerves artifacts...
Checking nerves_system_c2...
[GitHub] nerves_system_c2-portable-2.15.1+XXX-8-5052D84.tar.gz
No artifact with valid checksum
Found:
* nerves_system_c2-portable-2.15.1+XXXX-8-20CD3FF.tar.gz
=> Prebuilt nerves_system_c2 not found (no_result)
Found nerves_toolchain_armv7_nerves_linux_gnueabihf in cache
The name of my generated file is nerves_system_c2-portable-2.15.1+XXXX-8-20CD3FF.tar.gz. I am not sure where the checksum 5052D84 in nerves_system_c2-portable-2.15.1+XXX-8-5052D84.tar.gz is coming from.
I am reading this section
Is the checksum performed on the files listed in package_files(). In the list there are source files like “mix.exs”, “nerves_defconfig” etc. I am wondering what is the purpose of including source files. There are not even there in the generated artifact nerves_system_XXX.tar.gz file.
Thanks,
Venkat

The system
mix.exsincludes the configuration pieces needed to fetch the system artifact. Since that is a requirement for fetching, it is included in the checksum to prevent someone from altering those crucial configuration pieces when fetching. That said, if this is your own system, thepackage_files()is what is used to calculate and you can adjust as needed
