#16007 NETMF with STM32 ARM Cortex M3
Posted by Roceh on 28 July 2011 - 05:55 PM in Visual Studio
Anyone have any further development with this? I too, am using the M3 (SAM3S-EK board) under the advice of a wise man for a project. I have yet to figure out how to port it over to .NETMF. Any advice in a jumping-off point would be greatly appreciated!
I've done a partial port for a Cortex M4 (Freescale's Kinetis), if you wish to embark on a port for the STM32 some of that should be useful (NVIC, some Thumb2 tweaks). http://kinetismf.codeplex.com/
I hit a bit of a brick wall with the above now as i've run out of space with GCC in debug mode (even using 4.5), so i cant really do much more (i.e. Ethernet) Depending on your requirements you will encounter the same, unless you have the KEIL compiler. I'm waiting for the 1mb parts coming out later this year (hopefully...).
There are some 1mb STM32 parts out now (with Ethernet and USB host), unfortunately the dev-kits are nowhere to be found.

Wow thanks for the link. I like the fact that it's not per-board it's per-area. Sure, sometimes you may only want one or two boards but who couldn't use extras for a decent price? If you've got a 3x4" board they'll make you 8 of them for $100? Including shipping? That's fantastic. Love it.
Ah - the catch is no testing on 2 layer boards with a 15% fail rate. 4 layer and higher they test and have a 2% fail rate. Still, using the example above you'd have 1-2 boards fail per batch. Even with 2 failed boards you're talking about ~$18 per board. Not bad at all.
I've found seeedstudio http://www.seeedstud....html?cPath=185 to be cheapest for small prototyping even with the import duty & delivery costs. $35 for 10 boards of a max size of 10cm by 10cm.

#11612 SimpleNGen 1.0
Posted by Roceh on 03 April 2011 - 04:21 PM in Project Showcase
Tangent: for SimpleNgen, I probably could have saved myself a lot of work by letting GCC do the code generation. That is, we could narrow SimpleNgen's job to be that of translation from (a subset of) MSIL to C source, and then we would let GCC translate from C to ARM (or Thumb, or anything else). Perhaps I ought to have done it that way, but I wanted to play around with writing a compiler.
There was a partial implementation of modding gcc to compile cil to native - the frontend part of this project:

Although i suspect statically linking with stuff vala needs may cause license issues to arise.
