License file (EULA) for new machine in custom layer not found

[KChoj.2312]

Hi, I try to add a new layer and a new machine to the STM32MP1 Distribution Image. i followed the following tutorials tutorials:

https://wiki.st.com/stm32mpu/wiki/How_to_create_a_new_open_embedded_layer

https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Distribution_Package

However, I am still getting the following error:

WARNING: st-image-core-1.0-r0 do_populate_lic: Could not copy license file /home/user/workspace/STM32MP1/Distribution-Package/openstlinux-4.19-thud-mp1-19-10-09/layers/meta-st/meta-st-stm32mp-addons/conf/eula/stm32mp1-mymachine to /home/user/workspace/STM32MP1/Distribution-Package/openstlinux-4.19-thud-mp1-19-10-09/build-openstlinuxeglfs-stm32mp1-mymachine/tmp-glibc/work/stm32mp1_mymachine-openstlinux_eglfs-linux-gnueabi/st-image-core/1.0-r0/license-destdir/st-image-core/stm32mp1-mymachine: [Errno 2] No such file or directory: '/home/user/workspace/STM32MP1/Distribution-Package/openstlinux-4.19-thud-mp1-19-10-09/layers/meta-st/meta-st-stm32mp-addons/conf/eula/stm32mp1-mymachine'

So it looks that the bibtake still looks for the license file in the meta-st-stm32mp-addons, but not in my layer directory. Is there something I need to add to the configuration described in the tutorials from stm32mp1 wiki? I have already created the conf/eula directory in my layer with the link stm32mp1-mymachine -> ST_EULA_SLA.

Best regards,

Hi @Community member​ 

Reading this page :

https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machine

Did you do the symbolic link as described in Chapter 3.3 ?

Error message looks obvious that stm32mp1-mymachine -> ST_EULA_SLA. is missing in <path of STM32MP1_Distribution_Package>/layers/meta-st/meta-st-stm32mp-addons/conf/eula

Hope it help

Hi Olivier,

thanks for the response. I have also tried the intrustions in the mentioned link, but without any success. If I create the symbolic link with my machine name in the meta-st-stm32mp-addons layer it works, however when I put it in the eula directory in my own layer and create the license symbolic link there I get the No such file or directory error. I have also added the layers/meta-st/meta-st-stm32mp-addons layer as needed bsp in my machine conf file (NEEDED_BSPLAYERS).

So it looks like my layer path is not searched for the license. I probably missed something to add it to the path but cannot find what.

Hi @Community member​ 

Did you still have the issue ?

If yes can you please share your layer.conf ?

Thx

Olivier

Hi Olivier,

Yes - the problem still exists. i tried a few more changes in the layer and machine configs but without success.

My layer.conf file looks like this:

# We have a conf and classes directory, add to BBPATH
BBPATH .= ":${LAYERDIR}"
 
# We have recipes-* directories, add to BBFILES
BBFILES += "${LAYERDIR}/recipes-*/*/*.bb \
            ${LAYERDIR}/recipes-*/*/*.bbappend"
 
BBFILE_COLLECTIONS += "meta-mylayer"
BBFILE_PATTERN_meta-mylayer = "^${LAYERDIR}/"
BBFILE_PRIORITY_meta-mylayer = "7"
 
# Set a variable to get the STM32MP MX BSP location
STM32MP_MYLAYER_BASE = "${LAYERDIR}"
 
# This should only be incremented on significant changes that may
# cause compatibility issues with other layers
LAYERVERSION_meta-mylayer = "1"
LAYERSERIES_COMPAT_meta-mylayer = "thud"
LAYERDEPENDS_meta-mylayer = "stm-st-stm32mp-mx"

Hi @Community member​ 

Did you follow wiki page https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Distribution_Package ?

Seems that your layer.conf does not contain lines related to EULA :

EULA_FILE_ST_stm32mpmylayer = "${LAYERDIR}/conf/eula/${MACHINE}"

EULA_FILE_ST_MD5SUM_stm32mpmylayer = "8b505090fb679839cefbcc784afe8ce9"

#Inform bitbake for adding another location to search for licenses

LICENSE_PATH += "${LAYERDIR}/files/licenses"

And in your machine .conf add :

MACHINEOVERRIDES .= ":stm32mpmylayer"

Hope it help

Hi Olivier,

I'm sorry - I sent you the version of layer.conf after I removed the license entries and created the license link in the meta-st-stm32mp-addons/conf/eula directory (this is the only way I can make it work). I added back the lines you've mentioned and now it looks like this:

# We have a conf and classes directory, add to BBPATH
BBPATH .= ":${LAYERDIR}"
 
# We have recipes-* directories, add to BBFILES
BBFILES += "${LAYERDIR}/recipes-*/*/*.bb \
            ${LAYERDIR}/recipes-*/*/*.bbappend"
 
BBFILE_COLLECTIONS += "meta-mylayer"
BBFILE_PATTERN_meta-mylayer = "^${LAYERDIR}/"
BBFILE_PRIORITY_meta-mylayer = "7"
 
EULA_FILE_ST_stm32mpmylayer = "${LAYERDIR}/conf/eula/${MACHINE}"
EULA_FILE_ST_MD5SUM_stm32mpmylayer = "8b505090fb679839cefbcc784afe8ce9"
 
#Inform bitbake for adding another location to search for licenses
LICENSE_PATH += "${LAYERDIR}/files/licenses"
 
# Set a variable to get the STM32MP MX BSP location
STM32MP_MYLAYER_BASE = "${LAYERDIR}"
 
# This should only be incremented on significant changes that may
# cause compatibility issues with other layers
LAYERVERSION_meta-mylayer = "1"
LAYERSERIES_COMPAT_meta-mylayer = "thud"
LAYERDEPENDS_meta-mylayer = "stm-st-stm32mp-mx"

my machine conf has also the line:

MACHINEOVERRIDES .= ":stm32mpmylayer"

However I still have the same error and bitbake looks for the license file in the meta-st/meta-st-stm32mp-addons/conf/eula/ directory. Are there some requirements regarding the layer and the machine names (for example the *-layer suffix in the layer name)? My layer is called meta-mylayer and is located in the meta-st directory.

Hi @Community member​ 

To match with this layer.conf EULA link has to be done inside your own layer.

As per describe in section 2.3 of the wiki https://wiki.st.com/stm32mpu/wiki/How_to_compile_the_device_tree_with_the_Distribution_Package#Associate_EULA_with_the_new_demo_machine

First copy /conf/eula from Adds-on to your layer and then do the link

Olivier

[KChoj.2312]

That's right - I have already copied the eula directory to my own layer and created a link there, but bitbake still checks for it in the meta-st-stm32mp-addons layer. The only way I can get rid of this error is to create the link with my machine name in the meta-st-stm32mp-addons.

Can you please share result of :

bitbake -e | grep ^EULA_FILE_ST

and

bitbake-layers show-layers

Thanks

Olivier
