So with FoxTeam we finish yesterday the port of libmaple architecture to F4. But for some reason we decide to put inside the libmaple dirctly the ST libary. So will be more simple to mantain the code for the future release of micro .<br /> Here is possible to follow our thread : <a href="http://www.virtualrobotix.com/forum/topics/multipilot32-v3-f1-f4-and-new-vr-ide-pro?xg_source=activity" rel="nofollow">http://www.virtualrobotix.com/forum/topics/multipilot32-v3-f1-f4-and-new-vr-ide-pro?xg_source=activity</a><br /> Our target was porting Arducopter32 from F1 to F4 .<br /> Here there are working package :<br /> <a href="http://code.google.com/p/multipilot32/downloads/detail?name=stm32f4_REDFOX_OK%20-LastAlberto%2025-4-2012.rar&amp;can=2&amp;q=#makechanges" rel="nofollow">http://code.google.com/p/multipilot32/downloads/detail?name=stm32f4_REDFOX_OK%20-LastAlberto%2025-4-2012.rar&amp;can=2&amp;q=#makechanges</a><br /> We evaluate also the porting to chibiOS to Arducopter32 but was not so simple ... there are a lot of code to change .<br /> With this approach the firmware is ready for the first fly test that could be doing i think the next week . :)<br /> If someone would join to development is welcome.<br /> Best<br /> Roberto </p> http://forums.leaflabs.com/topic.php?id=1574#post-10367 Thu, 26 Apr 2012 11:47:14 +0000 olimexino 10367@http://forums.leaflabs.com/ <p>for H407 I made few prototypes to give away to people who want to develop but we have to do some functional test code to test them before we send, so these will be mailed next week as we have few days off to celibrate the Labour day May 1st - isn't it great to celibrate LABOUR day by not working :)))</p> <p>for E407 will be same - drop me e-mail with what you want to do with E407 and I may decide to send you one free of charge ;) </p> http://forums.leaflabs.com/topic.php?id=1574#post-10366 Thu, 26 Apr 2012 10:50:51 +0000 mabl 10366@http://forums.leaflabs.com/ <p>@redfox74</p> <p>I'm sure ChibiOS will fully support the STM32E407 as soon as Giovanni or I get the board in our hands.

The standard libmaple don't support 407 are you working on it ?<br /> So the other question is the iMX233 support linux , what revision ? On your site i see that there are also another board that use CortexA13 when will be available ?<br /> Best<br /> Roberto </p> http://forums.leaflabs.com/topic.php?id=1574#post-10358 Thu, 26 Apr 2012 01:38:32 +0000 olimexino 10358@http://forums.leaflabs.com/ <p>do you mean software?
