Hi list,
I've been looking at the ADT, and specifically building a custom SDK/ADT
for a particular board...
This is an ARM board, so I thought I'd set:
YOCTOADT_TARGET_MACHINE_arm="myboard"
Sadly, that doesn't work. I'm trying to understand why.
Despite changing YOCTOADT_REPO in my adt_installer.conf, the
adt_installer fails to find the cross canadian package group for my board...
Unknown package 'packagegroup-cross-canadian-myboard
Looking at the log, I see that the installer is still looking on the
yocto servers for (nativesdk) files. I can see that the nativesdk
locations are hard-coded in opkg/conf/opkg-sdk-i686.conf - so I guess it
isn't surprising that it can't find the right board, the Yocto servers
know nothing of myboard at this stage!
Seeing those hardcoded paths made me wonder if I was using the
YOCTOADT_TARGET_MACHINE_arm variable wrong...
Would it be 'right' to specify just 'arm' here? This is an imx6 board,
and TARGET_SYS = "arm-poky-linux-gnueabi". By my understanding, this
will affect which toolchain I get, among other things. I'd defintiely
like a machine specific sysroot, for example[1]
So - what's the meaning/point of this TARGET_MACHINE_arch option? I see
that there exists:
packagegroup-cross-canadian-imx53qsb_1.0-r0_all.ipk
- so clearly someone's felt the need to use something other than just
'arm' here in the past!
Has anyone else done an ADT for a custom board that uses the ADT
infrastructure?
Do you create a detailed overlay to the adt-installer recipe and change
config, etc?
It feels a little like I'm missing a step when generating the ADT that
tells it more important details about what I'm creating - if so, sorry
for the questions, but please could you point me there?
Thanks
Jonny
[1] I think that my images currently have to be called 'core-image-xxx'
to work with existing ADT scripts, unless I'm missing some config
somewhere, but that's a different issue that I'll dig into shortly
