ChibiOS Free Embedded RTOS

I have tried to compile IAR port with different data and code models and it works for small code model only. Meduim and large code models does not works; same as large data model. I have found that all models was supported in 1.5, so something was broken or this is IAR issue? Now it working with Sma...

I have updated entire OS path.
hal_lld.c contains CLK->CANCCR = STM8S_CAN_DIVIDER_VALUE line (for STM8S208 only), but structure CLK does not contain CANCCR in CLK_struct, it contains RESERVED1 instead.

Hi, I committed the IAR port and a demo for the STM8S-Discovery. I adjusted the intctx and extcts and I think those are now correct. The following points remain open: 1) The port is untested because the test suite cannot run in 8K, the LED flashes, that is all the testing done... 2) Compiler proble...

Apparently it is this thing upsetting it: if (notempty(&iqp->q_waiting)) chSchReadyI(fifo_remove(&iqp->q_waiting))->p_u.rdymsg = Q_OK; Something that works perfectly in all other compilers, including IAR for ARM. I am using the compiler version 1.30.1,the latest. I had those errors, but mad...

I have tried to debug application and found that IAR's compiler inside task functions call ?push_w4, that not simple pop'ed info from stack, it reads and writes stack directly, broking info in start_ctx structure. After defining task functions with __task prefix (do not save and restore context in t...

OK, I attached it here. ISR asm listing follows: \ In section .near_func.text, align 1 113 __interrupt void TIM2_OVR_UIF(void) { \ TIM2_OVR_UIF: \ _interrupt_15: \ 000000 8A PUSH CC \ 000001 84 POP A \ 000002 A4BF AND A, #0xbf \ 000004 88 PUSH A \ 000005 86 POP CC \ 000006 CD0000 CALL L:?push_l0 \ 0...

I've changed my project to be compatible with Cosmic and tried to run it. It works fine, so I think it is definitely IAR port issue. What about MCU, I'm limited with existing design and devices that was made in hardware, so I have no choice. For a little devices I prefer STM8S, at other side such MC...

Giovanni, thank you for trying to help me. If my tries to run my project under freeware versions of Cosmic or Raisonance will fail, I will try to port this on IAR again (or switch to atomthreads).

Processor selection was made because of its price, STM8S cheaper than any comparable AVR, for example it has 4 hardware PWMs. Some time ago I have shifted from AVRs to STM8S for a-little-cheap-things and Cortex for more complex tasks. But in this project compiler and MCU selection was made without r...

Yes, I understand this, but my knowledge is not enough to analyze extctx and intctx (and I do not know how to do this). I have tried to just put all theese 'push ?b15' and so on to inline asm, but failed (it just does not compile, it do not know what is '?b15'). I have compiled all without optimizat...
