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

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, ...

Re: Porting to Nordic Semiconductor nRF52

Just to add in, i have ported some basic modules for nrf51 and nrf52; uart, spi, leds, pins for various pca100xx boards (10000, 10001, 100028, 10031 and 100040). SD card with FAT is up running using the sdcard.py library. Also got an initial port of modusocket and modnetwork working, providing IPv6 ...
