AM625-Q1: Linux Docker Issue

Following on, I have managed to get past the initial problem using the following:

sudo apt update
sudo apt install docker.io qemu-user qemu-user-static binfmt-support

sudo docker run --rm --privileged multiarch/qemu-user-static --reset -p yes

sudo docker run -it --platform=linux/arm64 etc....

The next problem is as follows:

root@1354382fce98:~/ti-apps-launcher# make -C build

Any advice in order to be able to build this? We are keen to use the QT6 and therefore would like a solution.

The previous version I used was ti-processor-sdk-linux-am62xx-evm-10.01.10.04 and the ti-apps-launcher available at the time.  This all worked locally using the linux-devkit and compiled ok.

Following on again, I can now get to the compiled file, however when running the ti-apps-launcher on the hardware (using AM62X) at RT_BUILD=0, the program does not run and drops back to the terminal screen on the display.

The image:  tisdk-default-image-am62xx-evm-11.01.05.03.rootfs.wic.xz  — 856516 K, with the ti-apps-launcher already in it worked OK.

I now receive the following warning but it does complete:

After copying the ti-apps-launcher file the the usr/bin folder on the embedded platform, after it has tried to run the file, the size is now 0Bytes

Hi Andrew,
On my setup, I am currently at commit ebf367f of ti-apps-launcher repo.
At my end, I do see the warnings you showed:

Please verify the approximate file size and type from the above log. 
I added the following for AM62P in CMakeLists:

add_compile_definitions(SOC_AM62P=1) # if target is AM62P

Please make sure you have added that for AM62x.

I was able to validate the binary working by copying it into /usr/bin and running 'systemctl start ti-apps-launcher'.

Please cross check that your file was copied correctly, you should not have a 0 byte binary post copying/running.

Hi Divyansh,

Thanks for getting back to me on this issue.  It turns out the build had in fact worked and the binary could be executed on our platform (the AM62X).  The binary had become corrupted on copying to the SDCard, but it does now work.  

However, we have been in discussion with qt.io and may move on to using the Boot2Qt from them directly (this uses a BSP that TI/QT.io must have put together).  There seems to be some issues with the repo version using QT 6.8 and the V11 SDK using V6.9 and also the build time taken via the docker is very slow and not ideal for development.  I am sure TI are probably working towards a new version using the latest QT 6.10 and perhaps considering reverting to the method of compilation used under V10 SDK (this was relatively fast as it was all done locally).

Thanks,

Andrew

Hi Andrew,

We partnered with Qt for Boot2Qt but we were not involved in the development and it was front-ended by Qt developers.

Krunal
