crosscompile environment

[ed2k]

is it possible to have a cross compile environemnt. I have 3.x x86_64 sdk and 4.x armv7l sdk.
however the speed to compile on the prototype board is too slow. I would like to have a 4.x sdk working on x86_64.
My assumption is the 4.x SDK only changed epiphancy HAL (which I don't have source code), Can I use the 3.x e-gcc toolchian combine with 4.x header files and libs. Should I worry about cross-compile host program ? since the e-loader library is compiled under arm environment.

Thanks,

If you have the ARM libraries on your host system and an ARM compiler on your system you should be able to just use those libraries and compile the host program. I'm not entirely sure on the differences between SDK versions regarding Epiphany libraries (I don't have them to hand myself to quickly check) but it should just work.

Alternatively if that doesn't work, if you compile the available SDK source and give each compiler (ARM and Epiphany) the correct libraries from the current release I'm 99% sure that would work.

Hope that helps,
Simon

I use the cross compiler I downloaded from the CodeSourcery website. They provide support for multiple platforms, ARM cross-compiler is one of them.

As for the Epiphany code, you can safely use the e-gnu tools from esdk.3.* to generate the Ephiphany ELF-s and SREC-s.

There are a few changes to the eLib, but there are mostly behind-the-scenes.

ysapir,

Did you download the Lite Edition, a 30-day trial of the Standard Edition, or did you actually buy an edition?

@ubii - I used the free, no support Lite version. I did not need the fancy IDE for the kind of stuff we do here. Anyway, if using Eclipse, one can set the compiler to that installation to use the cross-compilation features.

ysapir,

Thanks, I will download the the Lite Edition as well, since I have no plans on using Eclipse.

There is a Xilinx Zynq specific version of this Code Sourcery ARM cross compiler. You download it from the Xilinx site here:

Digilent's support documents say this flavor of the compiler is needed to build a new Linux kernel for the Zedboard.

I have not compared it to the Lite version. Thus I don't know what, if anything, is different.
