Java SE on imx25

erhan14 — Mon, 03 Mar 2014 19:20:53 GMT

Hi,

I want to add Java SE support using OpenJDK with Cacao VM to imx258 demo board.

How can I configure ltib to prepare a flash image with Java support?

Thanks

Please use the following from Community :

“All Boards Java”

https://community.freescale.com/docs/DOC-1478

Note, for i.MX25 we should use ARMv5 packages :

Hi,

Thanks for the quick response.

I actually want to use opensource VM alternatives as Oracle Java is licensed for embedded use.

Thanks

If you are open to work in adding i.MX25 support in Yocto Project BSP (see FSL Community BSP) the later Java addition is quite trivial. We have the meta-java that has all this done and provides several Open Source VM alternatives.

Currently the i.MX25 is not supported by the BSP, that's why I put this remark there.

Is there a step by step guide for porting the official BSP to Yocto based one?

No; there's no such guide yet.

I can try to help if you want. Otherwise you can hire us (or someone else) to do the work. Either way works.

Initial support using mainline kernel and mainline U-Boot should be trivial. The i.MX25 2.6.31 kernel might be a little bit more problematic (due the fixes need for toolchain compatibility and others) but also doable.

Freescale released official Yocto release but I cannot find imx25 port in it?

As I said previously it has not been added.

Someone needs (or sponsor a company) to do it and maintain it.
