16FX Benchmarks

Hello Forum, I've done the first Benchmarks of the 16FX Ports. The benchmark was tested using 16, 32 and 48 MHZ Core Clock. Once the Optimization was turned off (O0 – files) and once the optimization was set to speed priority (OSpeed – files). It seems that the compiler generates fast and correct co...

16 FX Port, first issue

Dear Forum, Dear Giovanni, I’m presenting a first port of ChibiOS 2.6 Line for the Spansion 16FX Architecture. When adopting the scheduler I had to choose to use the hardware register set / switch instruction or use the conventional software way of pushing/poping registers during context switch. In ...

Re: Spansion 16FX Port

Hello Giovanni, i don't plan to have this port in the main trunk, because porting also the driver architecture to chibiOS would eat up quite some resources. Also i added some minor changes in your header files to take care for the different memory models of this port. + I wanted to create a branch u...

Re: benchmark software

Hello, thank you so far... I've adopted the benchsuite for 16Bit architecture so far. Now I've a problem, because Test Case 6.1 will faill during the following sequence: testevt.c . . . chEvtInit(&es1); chEvtRegisterMask(&es1, &el1, 1); chEvtRegisterMask(&es1, &el2, 2); test_asse...

Re: 2.6.3 chschd: chSchDoRescheduleAhead hangs

Hello Giovanni, thank you for answering, 16FX Architecture supports preemptable interrupts, but I use the same priority level for all chibiOS ISR-Functions, so in my opinion it should be the same than non preemptable ISRs, I've reserved high priority ISR for real time control loops in this porting a...

Spansion 16FX Port

Hello Giovanni, that you for the hint, in my port the task switch is performed in a dedicated hardware interrupt (delayed interrupt of the 16fx architecture), but the chThdSleep function puts a chSysLock()/chSysUnlock() pair around chSchGoSleepTimeoutS function. In my port the chSysLock() / chSysUnl...
