ChibiOS Free Embedded RTOS

Thanks Giovanni!

This was the hint you gave: "Writes are just a way to "assemble" frame composed of multiple parts."

I did not realise that by macWriteTransmitDescriptor() the driver should have only written to device's internal buffer and put that buffer on the ethernet only after ...

Hello Giovanni, thanks for response!

Ok, I understand about HAL API; driver's interrupt handling has been rewritten now.

One issue is still present what I'm struggling with. That one is around the lines with for(q = p; ...) macWriteTransmitDescriptor() in low_level_output(). I have said before ...

Hello Giovanny.

I wrote two drivers for W5500 Wiznet SPI Ethernet Controller with integrated TCP/IP stack. The first driver is implementing "plain" ethernet using hal_mac_lld and therefore needs LWIP to work; the second one is based on IoLibrary from Wiznet. I'm going to contact folks from Chibios ...

Thanks for clarification about the main thread!

Hello Giovanni.

I have been playing with a demo RT-STM32F303RE-NUCLEO64. Having defined CH_CFG_NO_IDLE_THREAD as TRUE I get compiler warning "chDbgAssert(otp != chSysGetIdleThreadX(), "sleeping in idle thread");" and later linker errors with undefined references to "ch_core0_cfg" and ...

Hi Giovanni,

common/msp430x is not supposed to replace the old GCC/msp430. msp430x port is relying on extended cpu instruction set: calla, mova and so on. The code would possibly become very rich in #ifdef constructions on trying to merge both ports together.

I've totally overseen TI libs in the ...

Hi Giovanni,

thank you for answer, it did help - see report below. mspgcc and IAR ABI are different. The main modification was changing from asm("mova r11, r15") to asm("mova r11, r12") to get IAR happy, added some other compiler specifics and it ran. I was able to compile the port with the mspgcc ...

I have been porting ChibiOS to msp430x (msp430f5437). The port seems to be complete so far, but running TestThread doesn't confirm this:

*** Kernel: 2.4.2
*** Compiled: Nov 2 2012 - 15:30:01
*** Compiler: IAR IAR C/C++ Compiler V5.10.1.50144/W32 for MSP430
*** Architecture: MSP430
*** Core Variant ...
