Hi Eddy,
I don't think build core-image-sato-sdk is the right approach. Have you looked into following the example of hello-mod under meta-skeleton, to use bitbake to build your kernel module? - Jessica From: Lai Eddy [mailto:eddy.lai...@gmail.com] Sent: Wednesday, January 30, 2013 7:54 PM To: Zhang, Jessica Cc: yocto@yoctoproject.org Subject: Re: [yocto] install and use "bitbake -c populate_sdk" Thanks Jessica, why I tried to use "-c populate-sdk" is because that I can find "core-image-sato-sdk" but no "core-image-basic-sdk" available, and my hardware is a samll jasperforest x86_64 target with 2 serial port and 1 ethernet port only, no display interface. I'm trying to find if any of following configuration suitable for my kernel module driver develop/debug: 1. with the x86_64 toolchain sdk installed on my x86_64 host , build my kernel module driver, then scp ".ko" binary to target for insmod/debugging, but the problem I have now is the "make" always pointing to /usr/src/3.2.x kernel source path (my host OS's kernel version), but not the linux-yocto target kernel (3.4.x) source/header path (and I don't know where's the proper 3.4.x target kernel header/source files, is it inside tmp/work/...? ) 2.build and run the "core-image-basic" on my target, and install the sdk created with "bitbake core-image-basic -c populate-sdk", but there's no "/usr/src/.." , "/lib/modules/3.4.x-yocto-stand/build" exist trying to build the "core-image-sato-sdk to see if that help for target develop now... Eddy 2013/1/31 Zhang, Jessica <jessica.zh...@intel.com<mailto:jessica.zh...@intel.com>> Hi Eddy, The SDK is meant to be used on development host for cross development instead of target. Sounds like you need an sdk image which contains the development tools and needed development library and kernel sources. Please refer to core-image-sato-sdk for how to customize your image to allow your do development work on target.

( it's FAT file system) or how to modify configuration to force build the .hddimg create ~"8GB" file system? 2. after that SDK installed into my target system, can I copy (scp) my own kernel module driver source code into the target system then make/compile and try insmod/debug the .ko there? or should I install the sdk on host system, then copy only the compiled .ko into target system for test/debugging?
