Tiva HAL Support

[Marco]

The Tiva port is added to the ChibiOS-Contrib repository on GitHub and automatically included in the ChibiOS svn repository under contributions. The other Tiva repositories are no longer updated.

Good work with the new repository.

Hello all,

It has been a while since I did some work on the Tiva port, until now.
I have been working on the MAC driver for the TM4C129x series for some time and it's working now. Because the MAC peripheral of the Tiva is almost identical to the MAC of the STM32 this was easier then expected. In the community repository you can find a demo for the TM4C1294 Connected Launchpad running a basic webserver using LwIP.

Good work, it is a synopsys IP so it is possible it is present also in other MCUs.

About the port, let me know if/when you think it is ready to go in 3.0 trunk, see the organization of other ports. It can also simply link your repository if you prefer this way.

It works like a charm! Nice work Marco!

Hi,

I've implemented the SPI low level driver for Tiva devices and added a demo in the testhal for TM4C123x devices.
The driver uses dma for all transfers except the polled exchange.
The demo is based on the STM32F4xx-SPI demo. You can find it in the community repository.

Hi,

I just discovered your ChibiOS port to Tiva C.
I am very interested by Chibi OS, and as I only own Tiva C boards, your work is greatly appreciated

I will definitely make some tests and return you feedback.

Thanks again !

Hi munrek,

Good to hear you want to try the Tiva port for ChibiOS.
I will really appreciate any feedback on the port since it's not used a lot yet. Don't hesitate to ask any questions.

Is there an IRC channel where we can directly talk to ?
