Re: Cannot get MMC to work under stm32f107

Hi Giovanni,

the problem is still there (as of rev 3378). I also just made a quick and dirty adaption of the f103-fatfs demo to my Olimex board - it shows exactly the same behavior.

Update: Added the Olimex STM32P107 demo

It's the Olimex Board, so it's SPID3.

Cannot get MMC to work under stm32f107

Hello, today I tried to upgrade my Chibios Code from revision 3223 to trunk (3313). Everything works great - except the mmc_spi interface to my sd card. It's still the same user code, and the hal interface has not changed between those revisions - so it ought to work, right? The execution of the Thr...

Re: Looking for help with my C++ thread class

Of cause you are right. But ROM consumption can be reduced further, even with libstdc++. I found some great tips here: http://www.webalice.it/fede.tft/cpp_on_ ... ricks.html

Re: Looking for help with my C++ thread class

Great! This seams to work. I even added a std::vector test - all fine! Of cause this will take up huge amounts of ROM... But it works nonetheless.

Re: Looking for help with my C++ thread class

Hi Giovanni, I just made some test with libstdc++. It uses standard malloc for allocation and has some os layer support for newlib (mainly ctype). In my tests I can create objects with new, and the constructor is called as well. Though I'm pretty sure malloc will collide with the ChibiOs allocator, ...

Re: Looking for help with my C++ thread class

That really is unfortunate. I also run into the C++ limitations quite often. For now I'm fine with the wrapper class, but improved C++ language support would really be great. Is there any documentation on the internet on what is missing and how to do it? EDIT: I know it is an awful hack, but in the ...
