[meta-ti] TI SysLink for am180-evm target

[Pow, Christopher (SWCOE)]

There's a file in the START_HERE partition of the SD card.  dvsdk_omapl138-evm_4_01_00_09_setuplinux.  Is that what you mean?

Thanks for the explanation RE the similar boards.  It sounds like you are saying that I am out of luck with regard to finding support for OMAP-L138 within meta-ti?  Do I have it right that DA850 and AM180x boards are just boards with ARM core processors on them, while the OMAP-L138 board is a board with an OMAP-L138 processor on it [ARM and DSP core]?  So the support that I'll get from meta-ti is *only* support for the ARM-core.  That makes sense, if I've got it right.

I am only responsible for the ARM-core side of the OMAP-L138.  I'm thus only concerned with building things that need to run on the ARM core, which includes the Linux BSP and ARM-core SysLink components.  Someone else is doing the DSP-core work [using SYS/BIOS] so I believe they will be integrating the DSP-core SysLink components.  

>From the perspective of the meta-ti capabilities, is there really anything above and beyond it that I need to have here?  My understanding of the OMAP-L138 is that the ARM-core is "in charge" and brings the DSP-core out of reset.  Once that's done they should be independent [except, of course, for SysLink communications].

Thanks for your helpful replies!

Christopher,

Can you please identify the TI SDK you received with the board - it's name and the version.

DA850, OMAP-L138 and AM180x are slightly different boards, even though very similar. As a matter of fact, from ARM GPP perspective they are pretty much the same, but the difference is in the peripherals, including the availability of DSP. Hence, you can build the am180x-evm (non-DSP) from meta-ti and run it on any of the above boards. BTW, why do you need SysLink just for ARM?
