The nrf51x22_256k_16k_s110_8.0.0.ld had a stack size of only 1kB, which
is way too low. Additionally, the indicated _minimum_stack_size (set at
2kB for that chip) isn't respected.
This commit sets the heap end based on the stack size (heap end = RAM
end - stack size) making it much easier to configure.
Additionally, the stack/heap size of nrf52 chips has been set to a more
sane value of 8kB.
Leave it enabled by default on all targets.
This is only possible when using UART-over-BLE (NUS) instead of the
default hardware peripheral. The flash area saved is quite substantial
(about 2.2KB) so this is useful for custom builds that do not need UART.
Feather52 target which is using SD s132 v.2.0.1 cannot compile
due to variable containing RAM start address is not used.
This patch enables the correct sd_ble_enable variant for this SD.
* ports/nrf/boards: Adding linker script for nrf52832 using BLE stack s132 v.5.0.0.
* ports/nrf/drivers/bluetooth: Updating makefile to add BLE_API_VERSION=4 if s132 v5.0.0 is used.
* ports/nrf/drivers/bluetooth: Updating BLE stack download script to also download S132 v5.0.0.
* ports/nrf/drivers/bluetooth: Updating ble_drv.c to handle BLE_API_VERSION=4 (s132 v5.0.0).
* ports/nrf/boards: Updating linker script for nrf52832 with s132 v.5.0.0 bluetooth stack.
* ports/nrf/drivers/bluetooth: Removing commented out code in ble_drv.c
* ports/nrf/drivers/bluetooth: Updating define of GATT_MTU_SIZE_DEFAULT for SD132v5 to be defined using the new name defined in the SD headers in a more generic way.
* ports/nrf/drivers/bluetooth: Cleaning up use of BLE_API_VERSION in the ble_drv.c. Also considering s140v6 API, so not all has been changed to >= if API version 3 and 4 in combo is used. New s140v6 will differ on these, and add a new API not compatible with the API for 3 and 4.
- Rename microbit_module_init to board_module_init0 which is the generic
board module init function.
- Add low priority callback registration of display tick handler in the
module init function.
- Rename init function to ticker_init0.
- Implement ticker_register_low_pri_callback (recycle of unused
set_low_priority_callback function which was unimplemented).
- Add support for registering 2 low pri callbacks. For now, one intended
for microbit display, and one for modmusic.
