ChibiOS Free Embedded RTOS

I did try (but didn't mention) the older 21.6.x series, but since you suggested I went even further back, all with the same outcome: 20.3.4 19.1.4 Then I noticed that the lwipopts.h in the F107 project that I was trying to get running was _very_ short compared to the one included with the HTTPS proj...

Hi all, I'm trying to get my feet wet with ChibiOS +LWiP. My end goal is to make a basic TCP server application which waits for a client to connect, and after some light protocol exchange, sends packets of binary data from a sensor in a stream fashion. I am currently using the NUCLEO144 STM32F746 bo...

Oh wow, thank you very much! I always forget about wayback, and in this case the text is plenty descriptive without the pictures.

Hi, I'm aware that the wiki site suffered some loss and is a WIP. Is there currently any way to follow broken links in the forums? Specifically, I'm trying to read the guide advertised in the second like of this forum posting https://forum.chibios.org/viewtopic.php?f=4&t=1485 Can I hand edit the...

Hi, I'm bringing up a new board based on an F7 and would like to do some basic tests with a small Chibi based firmware (test all IOs, peripherals, etc..) This board has a couple of SRAMs and gate arrays on the memory bus, and for this level of testing I'd prefer to just disable the DCache completely...

See also: https://forum.chibios.org/viewtopic.php?f=24&t=5893 I think there may be a problem with the openocd -rtos addition and ChibiOS 21. I've compiled the demos/STM32/RT-STM32L152-DISCOVERY application from ChibiOS_19.1.3 and the thread view works fine from gdb. When I repeated the same proc...

I had to do the same in order to link a c++ program with 21.6.0. Removing, or marking the offending duplicate functions with __attribute__((__weak__)) works for me as well.

Hi Kunal, First, thanks for this discussion, I wasn't aware of this feature. Second, I can verify that it works in gdb with simply "info threads" for me. I've added the aforementioned line to my openocd .cfg file. I connect gdb with "target ext :[myport]". I've also tested with &...

Aha, that's what I was missing. I (stupidly) assumed the threads were left alone, but I guess I wasn't thinking that "restarting" the OS was akin to a reboot. It also explains the undefined behaviour I was seeing when using dangling thread_t pointers from before the restart. It all makes s...

Thanks. I tried that and I think I am still doing something against the rules. So now when I wake, I call (with the system locked) stm32_clock_init(); // to re-set my clock ladder with proper timings halInit(); // Seems to be required after the above or else ST (TIM2) doesn't resume action chSysInit...
