ChibiOS Free Embedded RTOS

Hi, I'm trying to modify the ATtiny demos to work on an ATtiny85 and keep getting: /tmp/ccqAUctt.s: Assembler messages: /tmp/ccqAUctt.s:255: Error: illegal opcode jmp for mcu avr25 make: *** [../../ChibiOS/os/common/ports/AVR/compilers/GCC/rules.mk:174: build/obj/chcore.o] Error 1 make: *** Waiting ...

Has anyone had any luck with C++ on the AVR port of ChibiOS? I know the STM port can do it but when I try renaming main.c and moving it in the Makefile I get: /usr/lib/avr/include/avr/io.h:623:6: warning: #warning "device type not defined" [-Wcpp] # warning "device type not defined&qu...

Giovanni, I can put together a patch with my changes for the iGMP flag. It's only a couple lines, but my concern is that for my quick-and-dirty solution, I added #include stlib.h to lwipopts.h because with the IGMP true I needed to define LWIP_RAND as (uint32)rand() which may or may not be the right...

Hi all, I'm curious about what happened with #7 from geebee's driver. I'm trying to get a PTP driver working with multicast and when I add the NETIF_FLAG_IGMP flag to lwip_thread.c, everything seems to work. It looks like you may be working on a more flexible solution to the problem though, and I wo...

Yeah, I saw the verification fail when I was about halfway through that last post. It looks like the '-D' flag was added to the default avrdude command generated by the Makefile. So the flash was never being erased when I reprogrammed it. If I take that out everything works fine. Thanks for the help.

I have no reason to believe there's anything wrong with my hardware. I'm using a generic UNO clone and a usbASP clone. They've both worked fine in the past. I have the same results with both the RT and NIL projects. When I run 'make program' on the stable_16.1.x branch everything works fine, but whe...

Thanks. I can help if there's anything you need me to test.

Hi, It's been a while since I've been able to work on any of this and am having some issues getting the 18.2.x stable branch to run on an Uno. If I revert to stable_16.2.x I can run the demos and everything seems fine, but when I checkout stable_18.2.x, the board seems to program but the led doesn't...

Hi Giovanni, There are a couple of 8bit counters and one 16bit counter. It looks like in tickless mode the 16bit counter is used, and in periodic mode an 8bit counter is used. st_lld.c has the divider for tickless mode hard-coded to 1024. I played with that quite a while ago and I think had some suc...

Hi Giovanni, I've used the hal PWM drivers before and they're definitely nice. But for this project I'm driving an SSR that has an AC load. So once I enable the output line, the load won't turn back off until there's a zero-crossing, so I don't think traditional PWM would work. I think I want basica...
