Re: Porting to Nordic Semiconductor nRF52

Hi oliverr, It's great to hear that you are playing around with the port! :D I don't suppose anybody could help shed some light on this / point me to where I should be raising this issue? Any advice would be greatly appreciated! Feedback taken! Daniel has opened the "Issue tracker" in the repo ;) We...

Re: Porting to Nordic Semiconductor nRF52

Hi Matt, When I find a spare ten minutes I'll submit a PR for a readme. That would be awesome! :D Right now there is some kind of documentation in the wiki of the repo, but i guess a readme.md in the nrf5 folder would be very nice! Now to figure out what to build with this board... ;) Haha! That's a...

Re: Porting to Nordic Semiconductor nRF52

Awesome, Matt !!!!! :D :D I'm so happy that you got it running! Nothing is better than seeing that REPL prompt! ;) The issue you saw should be fixed now. I have updated main.c to work with two LEDs only. So, the LED(3) error should be gone. The thing is that there is a portion of code inside the mai...

Re: Porting to Nordic Semiconductor nRF52

Should work now. :D I found the correct UART RX/TX pins. Also got the serial upload to work on my side. I believe the max size is even less than 156kb for serial upload. I'll start looking into how to get ubluepy module fit inside the DFU image next. If you install the nrfutiils from the previous po...

Re: Porting to Nordic Semiconductor nRF52

Hi Matt, A short update on my experiments. It's getting closer! :) I managed to get the bootloader to jump to a working micropython Bluetooth REPL application (https://github.com/adafruit/Adafruit_nRF52_Arduino/tree/master/bin). It turns out after all that this bootloader jumps to 0x1c000 and not 0x...

Re: Porting to Nordic Semiconductor nRF52

Hi Matt, I have updated the branch to support the s132 v.2.0.1. Renamed the linker scripts and created a new one to offset the application to 0x1C000 which is the end of the v.2 softdevice. However, you might be right that the real offset is 0x1f000. The only way to figure this one out is to try to ...

Re: Porting to Nordic Semiconductor nRF52

I took a quick look at the bootloader hex file in the adafruit github repo, and this is what i found: s132 v.2 - size 0x0 -> 0x1c000 bootloader 0x74000 -> 0x798c8 Currently the nrf5_no_sdk branch does not support the s132 v.2 softdevice, so i will add support for this. Should not be to hard. I'll re...

Re: Porting to Nordic Semiconductor nRF52

Hi mattyt, I'm glad to hear that you have received your new kit :) If you haven't already got something up running, i will try to answer your comments and questions as best as i can. It would be great to get this board up running! The repository name "nrf5_no_sdk" might also be a bit misleading. Sof...

Re: Porting to Nordic Semiconductor nRF52

Hi, It's been a while since my last post, so why not give a short update on the branch progress; https://github.com/tralamazza/micropython/tree/nrf5_no_sdk The branch has now modules for: UART, SPI, Leds, Pins, ADC, I2C, PWM (nrf52 only), Temperature and RTC (real time counter). The modules are not ...

Re: Porting to Nordic Semiconductor nRF52

I have now pushed all i got to the dev branch in the previous post. So, please try it out. :) I'm not sure what to port next, so if there are any wish, please let me know (... or help out with the porting). Personally i would like to wrap up the BLE 6lowpan NIC for modusocket i started in the port, ...
