Hello All, I am little new to Gumstix and the questions might be naive ones. 1. I am using Gumstix Overo-Water COM (based on Cortex A-8) with Chestnut expansion board for an important embedded development project. I would like to know whether Gumstix have any short-term plans to provide Cortex A-9 support (OMAP 4-series) on Overo-Water or do I need to buy separate board (like DuoVero Crystal etc.)? 2. If I need more processing power with dual-core (in case I buy DuoVero board or any other dual-core board), can I use one core with file-system and the other one as standalone (bare-metal) core only used for processing? -- Thanks and regards Gaurav |

Hi Gaurav, Gumstix decided to create the DuoVero COMs to provide additional processing power in a similar COM form factor. The pin-out and connectors are slightly different than those on the Overo in order to bring out different signals giving users access to features of the OMAP4430 chip that weren't available in the AM35xx-DM37xx processors. --Ash On Tue, Nov 26, 2013 at 10:48 AM, Gaurav Chaturvedi <gau...@ns...> wrote: > Hello All, > > I am little new to Gumstix and the questions might be naive ones. > > 1.

Hi Ash, Thank you so much for the prompt reply. I will consider DuoVero board further, but I have one more question regarding building the kernel for this board (e.g. if I need some modifications like generating RT kernel). As mentioned on Gumstix dev. center website, the latest release is for kernel 3.6. Will it be fine to use on duoVero COM, if I use this release (based on Yocto: https://github.com/gumstix/Gumstix-YoctoProject-Repo) and build the 3.6 images (specially the kernel uImage)? As I am getting little confused on the correspondence between OMAP4x and kernel-3.6. Thanks again for the time and help.

Don't know if it helps but any changes for the DuoVero COM are in the 3.6 tree (https://github.com/gumstix/linux/tree/omap-3.6). Using another tree won't work. I'm building my images out of this tree and that's what the official images are from.

Hi, Thanks for your kind responses. @Conor: Yes, I am able to build using this as well, but I need to make it real-time kernel. For this, there are recipes provided with Yocto (successfully tried with 3.8 and 3.10 kernel with both dylan and dora), but I don't think any code branch is present for Gumstix Yocto 3.6 kernel (that supports duovero). Has anybody tried the RT-kernel building with Gumstix provided code (omap-3.6)? Would be of great help if possible. I am also trying to merge somehow the Yocto dylan and Gumstix provided omap-3.6. Will keep you posted if any success. @Trevor: Thanks for the link. Will try if required.
