AM62A7: Yocto build issue with SDK 9.0

Hi!

are you building on an Ubuntu 22.04 machine as recommended in the SDK docs? If not can you try this? Even if you did, can you try a new/different machine?

Also, can you confirm/double check that you followed all(!) of the setup/pre-requisite steps documented at https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-edgeai/AM62AX/09_00_00/exports/docs/linux/Overview_Building_the_SDK.html#prerequisites-one-time-setup?

Regards, Andreas

Hi Andreas,

We are using Ubuntu 20.04 machine for compilation.

After adding below 2 lines in ti-edgeai-firmware.bb file compilation issue is resolved but the name of the rootfs built is tisdk-default image and not the tisdk-edgeai image.

FW_DIR ??= "${PLAT_SFX}/vision_apps_eaik"

INSTALL_FW_DIR ??= "${nonarch_base_libdir}/firmware/vision_apps_eaik/"

All the steps and host packages are installed in the host machine referring the link

Hi,

I was building for am62axx-evm and I faced the same issue. With some poking around, I was able to resolve the issue by adding these 2 lines in the recipe file "~tisdk\sources\meta-edgeai\recipes-tisdk\ti-psdk-rtos\ti-edgeai-firmware.bb" :

FW_DIR:am62axx = "${PLAT_SFX}/vision_apps_eaik"
INSTALL_FW_DIR:am62axx = "${nonarch_base_libdir}/firmware/vision_apps_eaik/"

These should work. If they don't, please tweak these accordingly.

Best regards,

Hi Andreas,

There is a bit of confusion in the documentation given in below link

https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-edgeai/AM62AX/09_00_00/exports/docs/linux/Overview_Building_the_SDK.html

The build steps shows to download the configs/processor-sdk/processor-sdk-08.06.00-config.txt file but under yocto layer configuration it mentions to download processor-sdk-analytics-09.00.00-config.txt file

Which one should we use to build for SDK 9.0?

Are you able to build tisdk-edgeai file system using yocto?

the generated file system lists as tisdk-default image under deploy directory

I agree, this is not 100% clear. You for sure will want to use the processor-sdk-analytics-09.00.00-config.txt configuration file, as referenced from the Yocto layer configuration link in that section of the docs.

For AM62A, what you want to build to get started with the device and the SK board is the all-encompassing tisdk-edgeai-image image. It should generate image files/tarballs etc. with the same base name but I've not tried it myself. I'm kicking off a test build right now and report back when it is done.

Hi Vinay,

I have built tisdk-base-image since a minimal file systme was enough for me. 

Like you pointed out the documentation is sometimes not updated. So, we need to use it more as a guide and tweak the commands accordingly.
I used this command for configuring:
./oe-layertool-setup.sh -f configs/processor-sdk/processor-sdk-09.00.00-config.txt

I built it on Ubuntu 22.04.1 LTS. I only faced the "ti-edgeai-firmware" problem. After fixing that build succeeded.

How did you fix this?

My test build just finished, and I believe I ran into the same issue as OP/Vinay:

Hey Andreas,

Sorry about the problem. I added these 2 lines in the file "~tisdk\sources\meta-edgeai\recipes-tisdk\ti-psdk-rtos\ti-edgeai-firmware.bb" :

FW_DIR:am62axx = "${PLAT_SFX}/vision_apps_eaik"
INSTALL_FW_DIR:am62axx = "${nonarch_base_libdir}/firmware/vision_apps_eaik/"

You can refer to my file here:

Please search for "aiyps" in the file.

Good luck.

All,

I've since talked to the development team, and they said one step in the build documentation was missed. They are updating the documentation, but below is what I was given as the proper steps. Will try those out myself as well to double-check and confirm.

$ git clone https://git.ti.com/git/arago-project/oe-layersetup.git tisdk
$ cd tisdk
$ ./oe-layertool-setup.sh -f configs/processor-sdk-analytics/processor-sdk-analytics-09.00.00-config.txt
$ cd build
$ . conf/setenv
$ echo 'EDGEAI_BRAND = "edgeai"' >> conf/local.conf
$ MACHINE=am62axx-evm bitbake -k tisdk-edgeai-image

Regards, Andreas

Hi Andreas,

After adding the following changes tisdk-edgeai-firmware package issue is resolved but edgeai-tiovx-kernels.bb package does not build properly

it shows some undefined reference to function colorConvert_U8toNV12_i8u_o8u_armv8 added in the latest commit, kindly refer below commit

https://git.ti.com/cgit/edgeai/edgeai-tiovx-kernels/commit/?h=develop&id=048bb17ccee321d1dab0752e61be953f7b04e396

Is there any fix to build edgeai-tiovx-kernels package?

Vinay, Aiyappa,

after some debugging I found there was an error in the build steps provided earlier. The "edgeai branding" needs to be applied to conf/local.conf, NOT conf/layers.conf. I've updated the build steps accordingly.

Also, I confirmed that we must build using configs/processor-sdk-analytics/processor-sdk-analytics-09.00.00-config.txt, NOT the other configuration file for layer setup.

With both changes and trying clean builds however I'm still seeing a single error message (progress!). However debugging this some and making some change I was not able to resolve this quickly. The remaining error is shown below. I'll file an internal issue report and continue working this with the development team and report back here asap.

Remaining error:

Hi Andreas,

Any update on the issue?

Hi Vinay,

I'm supposed to have a joint debug session with the responsible developer today. Will keep this thread updated with any results, if any. I want to understand this (and fix, as needed) as much as you do so stay tuned.

Regards, Andreas
