Hi Yocto,
Thanks for all the support. I'm just working 2 weeks on Yocto and still no
expert. Adding extra features is working great when I want to do remote-debug:
EXTRA_IMAGE_FEATURES = "debug-tweaks tools-debug eclipse-debug"
Next problem I have is related to the 5150 evaluation board from TI. I have
soldered the BT.656 cable.
There are several ways to add this to my project:
1. Add in the program and call the I2C driver... but that's really ugly.
2. Add a kernel module for this chip. Following things I can do:
A) Create a new Board Support Layer:
yocto-bsp list karch
yocto-bsp create sogeti arm
After doing this, I am completely lost. It is using kernel 3.8, but the
ATMEL Sama5d3s is using 3.6.9, so this will not work...
B) Create a kernel driver in Eclipse.
But I can create a project, but not a kernel project... strange?
C) Use the C file, create a Makefile and cross compile.
I can compile a kernel-module and use insmod, but never done this with
Yocto... how to do this in the Yocto environment.
After doing this, I still have no idea if I should add this file to a
BB file or BBapend?
D) Some websites tell this driver is inside omap3-isp. Where to add this in
Yocto?
What do you think is the fastest/decent solution?
greetings from Holland,
Bart

Hi Bart,
It seems that tcf-agent was moved to eclipse-debug package group. So, instead
of adding tools-debug to image features, you should add eclipse-debug.
I think that the documentation for tcf-agent is not updated. Scott, can you
please update this?
Thank you,
Cristiana

Hi Cristiana,
I did step 2 from
http://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html#getting-the-images,
and changed the makefile a lot. I copied the file stubs-hard.h to
stubs-soft.h, but in the end I miss a dependency lssl, which I can't find yet.
When I try to do the same with hob and add tcf-agent, it becomes red and hob
stops without any result. Maybe I should hire the young girl from Yocto's
movie, for her it is simple.
I added tools-debug to my local-conf and start bitbake again. For HOB, I get
the RPM file which is useless... I need the sama5d34.dtb, uImage (kernel
binary) and a core-image[a-z]*.tar.gz
My local.conf has following:
BB_NUMBER_THREADS = "4"
PARALLEL_MAKE = "-j 4"
MACHINE ??= "sama5d3xek"
DL_DIR ?= "/home/mensfort/workspace_poky/downloads"
DISTRO ?= "poky"
EXTRA_IMAGE_FEATURES = "debug-tweaks tools-debug" <=== Just added
tools-debug.
USER_CLASSES ?= "buildstats image-mklibs image-prelink"
PATCHRESOLVE = "noop"
BB_DISKMON_DIRS = "\
STOPTASKS,${TMPDIR},1G,100K \
STOPTASKS,${DL_DIR},1G,100K \
STOPTASKS,${SSTATE_DIR},1G,100K \
ABORT,${TMPDIR},100M,1K \
ABORT,${DL_DIR},100M,1K \
ABORT,${SSTATE_DIR},100M,1K"
CONF_VERSION = "1"
SSTATE_MIRRORS = ""
PACKAGE_CLASSES = "package_rpm package_ipk"
I get following output from bitbake, no working output anymore.
| Error: packagegroup-core-boot not found in the base feeds (sama5d3xek
cortexa9t2hf-vfp cortexa9hf-vfp armv7at2hf-vfp armv7ahf-vfp armv6thf-vfp

Next time to try HOB, I will make a screenshot.
Maybe I am using the 'old' version 1.4.1. How to change to 1.4.2 or 1.5 ?
greetings,
Bart

Regarding tcf-agent, you can find documentation at
http://www.yoctoproject.org/docs/latest/mega-manual/mega-manual.html#getting-the-images.
If you already have tools-debug as extra feature in local.conf, and you receive
an error in Hob, can you please provide a screenshot with it?
