Compiling L5.4.3_1.0.0 BSP On Ubuntu 180.4 LTS – NXP Community
1. Compile tensorflow-lite with bitbake
bitbake tensorflow-lite -c do_configure -v -f
The following error occurs, at this time you can see the download of the wrong package
FAILED: ruy-populate-prefix/src/ruy-populate-stamp/ruy-populate-download
The specific path is
tmp/work/cortexa53-crypto-poky-linux/tensorflow-lite/2.5.0-r0/build/_deps/ruy-subbuild/ruy-populate-prefix/src/ruy-populate-stamp/ruy-populate-download

tmp/work/cortexa53-crypto-poky-linux/tensorflow-lite/2.5.0-r0/build/_deps/ruy-subbuild/ruy-populate-prefix/src/

Check whether there is a corresponding zip package in the modified directory, and copy it to the tensorflow pack folder created in the corresponding root directory.

3. Subsequent errors change in turn.

4. Execute this../cp.sh script during bitmake tensorflow Lite – C compile – V – f compilation, and tensorflow Lite will be compiled successfully.
