Unable to create debug filesystem

[gmax]

Hello, 

I enabled the generation of  debug filesystem by adding two variables in file build-openstlinuxweston-stm32mp15-disco/conf/local.conf as shown below to use with GDB. This step is  also mentioned in Yocto documentation (Link: https://docs.yoctoproject.org/dev/dev-manual/debugging.html#using-the-gdbserver-method ). 

IMAGE_GEN_DEBUGFS = "1"
IMAGE_FSTYPES_DEBUGFS = "tar.bz2"

When this option is enabled I get below dependency(?) error,

Does anyone know how to fix this?

Additional information:

Target HW : STM32MP157F-DK2

Target image : st-image-weston

Thanks,

Hi @gmax,

If you want to use GDB, I could suggest that you have a look at the STM32 MPU wiki (https://wiki.st.com/stm32mpu/wiki/Main_Page).

The following articles might be interesting for you:

• https://wiki.st.com/stm32mpu/wiki/GDB
• https://wiki.st.com/stm32mpu/wiki/GDB_commands

I’m aware that the above information doesn’t fix the problem that you highlighted, but nevertheless, I hope it might help.

Regards,

JC.

Hello @Jean-Christophe_TROTIN ,

Thanks for your reply. I did read those articles before but it mostly speak about how to use GDB rather than how to build for debug. Looks like I may need to switch from Distribution package to Developer package. 

Thanks,

gmax

After few research I got to know that the problem comes from the PACKAGE_CLASSES. Changing the default PACKAGE_CLASSES in local.conf from package_deb to package_ipk fixed the issue. 

# force the usage of debian package
#PACKAGE_CLASSES = "package_deb"
PACKAGE_CLASSES = "package_ipk"
