ChibiOS Free Embedded RTOS

Hi,

Thanks I will review your port as soon I finish the current things.

Giovanni

Hello,

The recent changes are available in the attachment where I made more fixes and also added testhal tests for ADC, RTC and RNG. Now I'm trying to figure out how to properly interact with CPU2 and implement corresponding features, such as IPCC and HSEM.

Best regards,
Ilya.

Hi,

Thanks, I am finalizing the 20.3 release right now, this will be matter for the next development cycle.

Giovanni,

I found that there are incorrect PR mask bits specified for EXTI2 and EXTI4 ISRs in the STM32/LLD/EXTIv1 driver. It could be useful to include at least this small fix in the current release. You can find the fix in the 0005-Fix-PR-mask-for-EXTI2-and-EXTI4-ISR-handlers.patch file in the attachment of my previous comment.

Best regards,
Ilya.

Too late...

Could you open a topic in "bug reports"? I will include this in 20.3.1.

Giovanni

I have not forgot about this, I need a board and it is difficult in this moment.

Giovanni

Has anything more become of this? I have a project I'm using the STM32WB55 in, and support would be helpful. I've started the process of updating the zipfile of patches from the beginning of the thread, but official support would be great.

Hi,

It is in queue but there are other things too.

Giovanni

Great to hear. Incidentally, the support as posted above is working OK for the most part, but specifically USB is NOT. I'm currently investigating what needs to change to fix this, though I'm pretty new to ChibiOS. Specifically, the USB_CDC example in `testhal/STM32/multi/USB_CDC` does not work when ported to the P-NUCLEO-WB55 - I also ported the example to the NUCLEO-F303RE I have, and it worked fine there. And a basic CDC example using ST's tools worked fine on the WB55. I'm currently digging through datasheets and other RTOSes (*cough* Zephyr) for clues, and at the moment all I've noticed is some interrupt differences, and the HSI48. This might take me a while.

Hi,

USB is always the same, it must be some tiny clock or GPIO detail.

BTW, is there support in OpenOCD for this device?
