text segment size ( 211304) plus data segment size (2732) plus BSS/zeroed
segment size (7776) equals the total program size 221812, which written as
a hex number is 0x36274

Re: [beagleboard] Re: Help with Cross Compile of first HelloWorld App

2014-04-10 Thread Hussam Hertani 
Piotr I know that the linaro toolchain will work with Debian/Ubuntu armhf
images
. Will it also work in the same way with angstrom?
...I thought that angstrom needed a different toolchain for cross-compiling
applications. But I could be wrong.

 Just compile the kernel following the commonly known instructions for BBB.
 On of the step, will download appropriate gcc toolchain, it will be named
 like gcc-linaro-arm-linux-gnueabihf-4.8-2013.10_linux/.
 That's it.

 Regards,
 Piotr.

 I'm a newbie and this is my first post.

 I just got started with building my first HelloWorld style app to test
 the cross-compile capabilities of Eclipse/CDT, The app compiles
 successfully and generate the expected HelloBeagle.elf executable. However,
 when I transfer it to my beagle and attempt to run, I get an Illegal
 instruction error.

 I've watched every video I could find (Thanks Derek Malloy) and I still
 can't find the reason for the error. Obviously it's not generating the
 right code base, but the build output does show that it it aimed for the
 cortex-a8 processor which I believe is correct for the beaglebone black.

 I would appreciate any suggestions or ideas!!

 Thanks
