Re: Upgrade of RTC api.

TO SUM UP: I would like to RFC in rtc.h api to enable setting multiple alarms on single RTC. Here is git diff on rtc.h diff --git a/include/rtc.h b/include/rtc.h index 40c24c5..44beb3d 100644 ---

Re: Upgrade of RTC api.

Hi, (quick resend for the thread owner) Current API already supports multiple instances of a given device driver, so that's fine. That is missing indeed. Or, more precisely, the only current way to

Daily digests...

Folks, We don't appear to have had any daily gerrit digests since 7/3/2017. Does anyone know what this issue is? Cheers /Marcus

Re: Testing random number generators

Would be a great idea. Especially useful to bring to the surface RNGs that have been interfaced to the system without a whitening filter... Daniel.

Re: Testing random number generators

Seems like a pretty worth while thing to work on. We have some support for a few random number generators in the tree already (drivers/random). So I think a test app as you described shouldn’t be

Re: Upgrade of RTC api.

Do you think we will have systems with multiple RTC in them? I’m generally for supporting multiples of a given device type, just wonder about RTCs. We need to have a standard view of time

Re: Odp.: Graphics and Zephyr

Interesting product indeed but beware of the "100% open" on the front page. ugfx is not open source... merely "open". Daniel.

Odp.: Graphics and Zephyr

Hi Bill, I'm not sure if ugfx has been ported to Zephyr but you can check it anyway. I've heard good things about it. https://ugfx.io/ Od: zephyr-devel-bounces@... <zephyr-devel-bounces@...> w

Hi, You can combine those descriptors together to have multifunction device. http://www.beyondlogic.org/usbnutshell/usb5.shtml (I have not tried it myself) Best regards Andrei Emeltchenko

Re: [RFC] MPU support for debugging

This is a great topic to bring up. In addition to an MPU policy to protect threads for debugging, we do need to specify a system-level policy that get applied at boot, even if we are not protecting

Re: [RFC] MPU support for debugging

Yet another example that shows the importance of laying out early what the different MPU regions will be used for, as stated in the top comment in my original reply to the RFC.

Re: [RFC] MPU support for debugging

I had planned on checking user pointers unconditionally, I think it's a common programming mistake. When running in supervisor mode on behalf of a user thread, we should make sure any buffers passed

Re: [RFC] MPU support for debugging

I would like to add one more point to the discussion. It is maybe not directly related to the topic but should likely be considered when designing MPU support. Occasionally, mainly in

Ben, Thanks for the explanation! It is very clear now. Regards, Jun

Re: [RFC] MPU support for debugging

Agreed, but I think this can be made optional if the application is trusted and user-space is used more as a debugging aid. Although, that's Yet Another Kconfig configuration to verify.

Hi Jun, <duration> is the time before the first timer expiry, and <period> is the period at which it will expiry subsenquently. If you specify a <period> of 0, the timer only fire once. e.g. If the

Re: Reg: Command handling Via USB driver

Hi Thanks for the reply But as of now with the available zephyr, the USB can work either as DFU flashing or as UART over USB (CDC) and not both functionalities together. We have a requirement at End

Re: [RFC] MPU support for debugging

And validation of all the arguments passed into each function call. No point going to all this trouble if userspace code can pass in dodgy pointers or lengths etc. to the kernel. -- Tixy
