ValueError: incompatible .mpy file

[devnull]

Have just updated from 1.9.4 to 1.10.

Build of 1.10 was successful and loaded and running.

Also went into mpy-cross folder and did

Code: Select all

make clean
make

And the new file was generated, but when I build a file using this new mpy-cross I get the error:

Code: Select all

ValueError: incompatible .mpy file

Now I know that the eroor message is self-explanatory, but I am stumped

Any suggestions ?

mpy-cross is normally built and called for frozen bytecode by Makefile. That call uses the option -march=armv7m
Besides that: are you sure that the fresh built mpy-cross is called and not another copy that is in the path? Things like that use to happen to me.

Hi Robert;

Was just about to update when I saw your post, thanks for helping.

The problem was with a sub-module that was loaded inside the module I was calling, and not the file itself
