Config Tools for i.MX 12.1: Ubuntu cannot locat python

ad-fsdev — Mon, 19 Dec 2022 10:31:45 GMT

Hello,

I am using config tools for i.MX ubuntu version 12.1 to calculate RAM timings. I figured out that after creating a new project code preview does not work because python couldn't be found. swtool.log shows that one of following errors "Python path does not exist: /opt/nxp/i.MX_CFG_v12.1/bin/python39" because after installation only "/opt/nxp/i.MX_CFG_v12.1/bin/python38" is available and python version is 3.10.0a2+.

Would you please correct this. Thank you.

Whish you Merry Christmas.

I have the same issue. Any update on this?

Hello,

you can set your own path in the tool.ini to -Dpython.dir=python39 (/opt/nxp/i.MX_CFG_v12.1/bin) and it should work too. But the failure (maybe copy paste) is available from my understanding.

Happy new year.

Thank you, I was able to fix the tools.ini file.

The folder that comes with the install package is called python38 but the ini file is set to python39.

That cleared the python error but then I get another error:

"Error DDRC Failed to generate code due to erroneous values used to configure DDR!"

I have all of the values set to the defaults for the MX8M Mini evk and I still get this error. Every time a try to adjust a value I get a message saying "the specified value is not supported".

The same values work properly when I use the Windows based tool.

If I ignore the message and try to run the tests It fails with the following message:

/opt/nxp/i.MX_CFG_v12.1/bin/python38/bin/python: Error while finding module specification for 'memtool.s' (ModuleNotFoundError: No module named 'memtool')

One thing I just noticed - If I save my configuration the
"Error DDRC Failed to generate code due to erroneous values used to configure DDR!"

message goes away but when I try to run the tests on my board I get the message about missing memtool.

I also got Python related errors when trying to generate the `lpddr4_config.c` file for U-Boot
with the i.MX config tools version 25.06. It looks like the tool does not ship the
correct Python version since `python3.13` is symlinked to `python3.12` in the `bin` directory.

I got it working and successfully generate the config file on Debian 13
which uses Python 3.13 as system wide python by replacing the `python3.13` symlink with a link to
the system python. This can be done with the following bash command:
`(cd i.MX_CFG_25.06/bin/python3/bin && rm python3.13 && ln -s /usr/bin/python3.13 python3.13)`

Additionally, the `tools` binary has to be executed directly from the `bin` directory, e.g.
`(cd i.MX_CFG_25.06/bin && ./tools)
