NXP mx8平台tensorflow-lite build error

 

NXP提供的方案

Compiling L5.4.3_1.0.0 BSP On Ubuntu 180.4 LTS - NXP Community

1、使用bitbake编译tensorflow-lite

bitbake tensorflow-lite -c do_configure -v -f

出现如下错误，此时可以看到下载错误的软件包

FAILED: ruy-populate-prefix/src/ruy-populate-stamp/ruy-populate-download

具体路径为

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/

查看改目录下是否有相应的zip包，有复制到相应根目录下创建tensorflow-pack文件夹中。

第二个错误；

tmp/work/cortexa53-crypto-poky-linux/tensorflow-lite/2.5.0-r0/build/pthreadpool-download

在此目录下查看是否有zip，在copy到到tensorflow-pack文件夹中

ninja: build stopped: subcommand failed.

3、后续错误依次更改。

4、在进行bitbake tensorflow-lite -c compile -v -f 编译的过程中执行此../cp.sh脚本，此时tensorflow-lite即可编译成功。

#!/bin/bash
mkdir -p ./../build-imx-robot/tmp/work/cortexa53-crypto-poky-linux/tensorflow-lite/2.5.0-r0/build/_deps/ruy-subbuild/ruy-populate-prefix/src/
