| 1 | Hi, |
| 2 | |
| 3 | 1. You should also consider Openembedded www.openembedded.org. |
| 4 | This is a true cross-compilation framework. You can take a fast |
| 5 | multicore x86_64 host and build software for all kind of targets. |
| 6 | |
| 7 | The build-tool bitbake was inspired by Portage: |
| 8 | http://docs.openembedded.org/bitbake/html/ch01.html |
| 9 | |
| 10 | The config files for the supported hardware are: |
| 11 | http://cgit.openembedded.org/cgit.cgi/openembedded/tree/conf/machine |
| 12 | |
| 13 | The TMS320DM356 is supported by |
| 14 | conf/machine/dm365-evm.conf |
| 15 | http://cgit.openembedded.org/cgit.cgi/openembedded/tree/conf/machine/dm365-evm.conf |
| 16 | |
| 17 | Just set |
| 18 | MACHINE="dm365-evm" |
| 19 | DISTRO="angstrom-2010.x" |
| 20 | in your local.conf file and call |
| 21 | bitbake minimal-image |
| 22 | |
| 23 | But I have not yet built for the target dm365-evm. |
| 24 | |
| 25 | The description how I have used Openembedded for the i.MX35 is: |
| 26 | http://en.gentoo-wiki.com/wiki/Phytec_phyCORE-iMX35/Openembedded |
| 27 | and for the MPC5125 is: |
| 28 | http://en.gentoo-wiki.com/wiki/Freescale_TWR-MPC5125/Openembedded |
| 29 | |
| 30 | 2. I have tried to use Gentoo for cross compilation on x86_64 or x86 |
| 31 | hosts for arm and ppc targets. There has been always at least one |
| 32 | software package which cannot be cross-compiled. You have to fix this |
| 33 | before you can go on. |
| 34 | |
| 35 | The description how I have tried to cross-compile Gentoo for the i.MX35 |
| 36 | is: http://en.gentoo-wiki.com/wiki/Phytec_phyCORE-iMX35/Gentoo/Desktop |
| 37 | |
| 38 | 3. You can try to use qemu and emulate the native cross-compilation |
| 39 | as described in |
| 40 | http://www.gentoo.org/proj/en/base/embedded/handbook/index.xml?part=1&chap=5 |
| 41 | |
| 42 | 4. You can compile native on the target by using stage3, but are you |
| 43 | sure that you want to do it all the time? Do you have enough memory |
| 44 | there? Do you have swap space? Is the CPU fast enough? |
| 45 | Do you have always the right board at hand? |
| 46 | |
| 47 | 5. There is also another true cross-compilation framework from |
| 48 | Pengutronix http://pengutronix.de/index_en.html. The description how I |
| 49 | have used it for the i.MX35 is: |
| 50 | http://en.gentoo-wiki.com/wiki/Phytec_phyCORE-iMX35/Pengutronix/Embedded |
| 51 | |
| 52 | Pengutronix supports ARM, but I don't know, if it already supports the |
| 53 | TMS320DM365. |
| 54 | |
| 55 | I hope this helps. |
| 56 | |
