ChibiOS Free Embedded RTOS

Thanks!
There is code in crt0_v7m.S that initializes MSP. I added in my Makefile
UADEFS = -DCRT0_FORCE_MSP_INIT=TRUE

and now all seems to be good.

Hello, I'm using STM32F767I, ChibiOS 17.6.0, arm-none-eabi-gcc 7.1.0 compiler. I'm trying to implement bootloader using nDBOOT and nDBANK option bits, but I'm having buffer overwrite problems. The problem appears to be that in USART interrupt handler the stack pointer of the IRQ handler points somew...

Hello, I'm using ChibiOS_17.6.0, STM32F767II board with enabled all 3 CANs. If I leave CAN3 with the default acceptance filters it won't receive any frames (in contrast CAN1 and CAN2 receive messages). The problem appears to be in hal_can_lld.c, lines 165-173. For CAND3, if there is CAN2 enabled, th...

Thanks!

Hello, I try to measure the width of a pulse using a general purpose timer. The function is invoked as callback to the EXTD1 driver, triggers on EXTI2 event: void _extIRQ(EXTDriver *extp, expchannel_t channel) { if (_edgeChange == 0) { gptStartContinuous(&GPTD5, 0); //greatest possible reset val...

Thanks!
At my baud rate the transmission time is almost exactly 1ms per byte. I incorrectly assumed that sdWrite blocks until all has completed. But it blocks until the data byte goes in the transmission register TDR.

Hello, I can't explain the behavior of the following code, compiled on STM32F105 with Chibios 16.1.8: for (uint32_t i = 0; i < size; ++i) { sdWrite(DRV, &data[i], 1); osDelay(time); } Send data on the serial line, there should be a pause between each byte - time in ms When I observe the transmis...

Hello,
There is compile error in cmsis_os.c on line 189:
tp->state = CH_STATE_CURRENT;
Probably it should be:
tp->p_state = CH_STATE_CURRENT;

I added in the initial configuration of the driver for the Reception Data Field Length linflexp->UARTCR.B.RDFL_RFC = 3; //receive 4 bytes And in the RX ISR: sdIncomingDataI(sdp, sdp->linflexp->BDRM.B.DATA4); sdIncomingDataI(sdp, sdp->linflexp->BDRM.B.DATA5); sdIncomingDataI(sdp, sdp->linflexp->BDRM....

It is configured at 160MHz, which should be maximum performance. I took that code from what S32 design studio generates -I don't suspect errors there but I'll dobule check it. Another project is communicating with the MCU at 1Mb/s without any overflow problems - but it doesn't use any OS and is comp...
