Hi Kaspar, I'm just searching for a very small device - and the device I have in my focus STM32L432 is running at it's nominal speed of 80MHz. Regards, Neo On 12.06.2017 13:06, Kaspar Schleiser wrote: Hi Neo, On 06/12/2017 12:42 PM, Neo wrote: Now my question - what is the minimum clock

Hi, I think the wisest choice is probably to switch to FEI mode first to use the internal oscillator before booting a new image. That is the same mode that the mcu comes up in after a hardware reset. There are some relevant PRs open on GitHub for the Kinetis clocking: https://github.com/RIOT-OS/RI

I forgot to mention that you will need a development snapshot of openocd for the kw41z. See my kwxxz-support branch at https://github.com/gebart/openocd/tree/pr/kwxxz-support?files=1 Best regards, Joakim On Jun 12, 2017 14:21, "Emmanuel Baccelli" wrote: > Hi Joakim, > > FYI I just got hold of s

Hi again! I just made it work, though is super strange why it works… I did: static void cpu_clock_init(void) {     /* setup system prescalers */     SIM->CLKDIV1 = (                            SIM_CLKDIV1_OUTDIV1(0) | /* Core/System clock divider */                            SIM_CLKDIV1_OUTDIV2

Hi RIOT devs! I’m currently working on the RIOT port for MCUBoot[1], which takes the frdm-k64f board as a reference board, and that’s also supported by RIOT and other OSs using MCUBoot. My first goal is to provide a “bootable” image compiled in RIOT and booted by MCUBoot built for mynewt. The

Hi Joakim, FYI I just got hold of some kw41z boards. gnrc_networking compiles on both OS X and Ubuntu (Vagrant). Now I am trying to debug some trouble with jlink (can't flash the board yet). Cheers Emmanuel On Thu, Jun 8, 2017 at 1:09 PM, Emmanuel Baccelli < emmanuel.bacce...@inria.fr> wrote:

Hi Neo, regarding clock speed I'm not aware of any restrictions on the `gnrc_border_router` example (though there are some on space, which most STM32 MCUs should fulfill). It might get slower and depending on the traffic it might get overwhelmed, but I think no one ever made any experiments for th

Dear RIOT-developers, up to now I have worked with a beaglebone as a 6LoWPAN border router. I want now to change to a microcontroller based system (STM32 family). Now my question - what is the minimum clock speed of such a controller to be able to work as a border-router? Thanks a lot! Best
