Cross Compiling #6

Closed arahowerya closed 4 years ago

arahowerya commented 4 years ago

Hi Guys, The project looks great, and seems very impressive, have been looking at it for a few hours.

Something's a little unclear, I have a ATSAMA5D27-SOM1-EK board with a TM43xx LCD attached, and I can get the examples from the linux4sam prebuilt yocto image demo archive to run on the screen - all looks great.

I can also make compile and run all the examples perfectly on a local ubuntu machine.

However, it's unclear how do I cross compile to the target? How do I end up taking for example the basic.cpp example and ending up with the egt_basic binary that's on the example yocto image?

Would appreciate any help Kilian

There is a dedicated SDK on the page: https://www.linux4sam.org/bin/view/Linux4SAM/SoftwareTools#Yocto_Project_SDK For ATSAMA5D27-SOM1-EK, it's this one: https://files.linux4sam.org/pub/demo/yocto-sdk/poky-atmel-glibc-x86_64-microchip-graphics-image-cortexa5t2hf-neon-vfpv4-sama5d2-xplained-sd-toolchain-3.1.sh Install it, follow instruction on how to use it and EGT libraries must be present and ready to cross-compile. Tell us if you find difficulties in the process. Best regards, Nicolas

Thanks for that, I've been using an old build of yocto for a while now, I'll try this out. Please consider pointing to that link in the README, I googled everything I could re: EGT and couldn't find that. Thanks again for your help Kilian
