anshulkhare — Tue, 25 Sep 2018 10:53:54 GMT

Hello All,

i have an T2080RDB-PC board, for that i have downloaded SDK 2.0 and compiled successfully

and on T2080RDB board i have flashed my uboot, dtb ,kernel and rootfs images via tftp,

and i am able to observe the logs correctly,

now i want to add one sample application of "hello world"

for this i have created my own layer and in layer i have created "hello_world" application,

when i am compiling with command bitbake hello_world application is not compiling and throwing error

"nothing provides hello_world".

and when i am giving command bitbake -b hello_world application is compiled and binary is generated,

when this binary i am trying to load on T2080RDB board via USB and trying to execute at that time it is giving error "no such file or directory".

please tell me how to add application and how to add the application as a part of Rootfs.

Thanks in advance

Regards,

Anshul

The "No such file or directory" usually means that your application require additional file or library.

Test your board using static library compiling for your software.

Use similar command for gcc:

$CC test.c --static -o test.elf

Have a great day,
