I asked, in few weeks a low cost board based on the SPC563M64 should be released, it is an 80MHz powertrain device with ETPU.

Giovanni

Great news!!!

I will definitely get one

Did you also receive any price tag? Probably some other features you might want to tell us?

Initially the price will be higher than STM32 Discovery kits but they are mentioning high quality construction for automotive.

Giovanni

Do you know if there's gonna be a free etpu compiler?

That's the only major drawback right now.

It is not planned as far I know but something I wanted to try is to create some kind of macro-assembler for the ETPU, is the C language really required? such a restricted subset too, it is not really C anymore.

Since the instruction set is rather limited, an assembler would probably do

But what about a free tool chain for these MCUs? And for the ETPU? Update: I see your have responded already, I have missed the 2nd page of this topic.

My EFI project is getting some traction and the community is trying to figure out it we should stay with stm32 or look around for other options. To be honest, questions are also asked what RTOS is most suited for automotive application and right now I am trying to figure our the difference between ChibiOS and ERIKA.

Anyway, is is great to see ST using ChibiOS as in this SPC5-STUDIO!

Erika is an OSEK compliant RTOS, ChibiOS is not, this is the basic difference. ChibiOS has more fueatures, OSEK specifies a very simplified RTOS.

SPC5Studion contains ChibiOS and also another OSEK-compliant RTOS, both can use the HAL (derived from the ChibiOS HAL).
