Hi Jessica,

downgrading from Ubuntu 11.04 (32 bit) to Ubuntu 10.04 (32 bit) and following the ADT manual procedure HelloWorld demo works.

[JZ] This I’m assuming you strictly follow the ADT manual and use the Yocto project built out toolchain, right?  Why downgrade from Ubuntu 11.04 to 10.04? I don’t think you need to do that unless 10.04 is what you want.

I noticed that ADT creates an armv5 tool chain instead building the toolchain using Freescale layer (because I need to deploy the application on a iMX53QSB) it creates an armv7 tool chain (that is the right processor architecture).

Can this create problems?

[JZ] In that case, you need to build out an armv7 toolchain.  The key is to add the Freescale layer and set target MACHINE appropriately.  And use that toolchain  for your cross development.  It should work.

Thanks

Giovanni

Hi Giovanni,

Can you following the ADT manual and use the built 1.2.1 toolchain tar ball?  The meta-ide-support is supposed to be used under build tree instead of copied over to /opt/poky.

Cheers,

Jessica

Hi,

I need to deploy a C application that I have made on a Freescale iMX53 QSB. 

First I wanted to test the cross-compilation environment building the Hello World demo but I got some issues. 

I made the following steps:

• download yocto denzil
• source oe-init-build-env
• edit local.conf and bblayers.conf files
• run 'bitbake meta-ide-support'
• copied the resultant sdk in /opt/poky
• installed Yocto Eclipse plugin
• Configured the plugin as following

• toolchain root location: /opt/poky/1.2.1
• sysroot location: /opt/poky/1.2.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi

When I build the project I get the following error:
