Expand description

Tock kernel for the Nordic Semiconductor nRF52 development kit (DK), a.k.a. the PCA10040.

It is based on nRF52838 SoC (Cortex M4 core with a BLE transceiver) with many exported I/O and peripherals.

nRF52838 has only one port and uses pins 0-31!

Furthermore, there exist another a preview development kit for nRF52840 but it is not supported yet because unfortunately the pin configuration differ from nRF52-DK whereas nRF52840 uses two ports where port 0 has 32 pins and port 1 has 16 pins.

Functions§

main⚠
Main function called after RAM initialized.
start⚠
This is in a separate, inline(never) function so that its stack frame is removed when this function returns. Otherwise, the stack space used for these static_inits is wasted.
