I added the powerdown func by GIC in mbed_application because Cortex-A9 use GIC instead of NVIC.
This process prevent unexpected interrupt when updating software by using bootloader.
1. Introduce S/W interrupt enable/disable to reduce calls to TIMER_EnableInt/TIMER_DisableInt.
2. Allow dummy interrupt because clear interrupt flag is not synchronized.
3. Enable LPTICKER_DELAY_TICKS to make lp_ticker_set_interrupt non-blocking.
Mark mbed-os-tests-mbed_hal-common_tickers/time_cpu_cycles not in-lined.
Otherwise, time_cpu_cycles may be in-lined somewhere and takes different
CPU cycles on invocation.
Setting ""nsapi.dns-cache-size": 0" still left some of the DNS
caching code in. Add crude #if to remove all of it.
This allows one to save 429 bytes of flash and 48 bytes of RAM on
ARMC5 builds.
* Elevate RTC2 interrupt priority to same level as UARTE to prevent
race condition on shared variables.
* Remove unused TXDRDY event code.
* Fix typo in macro.
It has been noticed that there is a problem with us ticker on NRF_52840 board after 32 bit counter has been used for us ticker on NRF52 family boards.
Currently NRF52 symbol is defined only for MCU_NRF52832 (not for MCU_NRF52840) and based on this symbol 16 or 32 bit counter is selected (16 bit for NRF51 family and 32 for NRF52 family).
Since MCU_NRF52840 defines NRF52840_XXAA and provides 32 bit counters, 32 bit counter should be selected also when NRF52840_XXAA symbol is defined.
In serial_tx_active and serial_rx_active functions,
we check the internal state value with
HAL_UART_STATE_BUSY_TX = 0x21U,
HAL_UART_STATE_BUSY_RX = 0x22U,
It seems that value can also be :
HAL_UART_STATE_BUSY_TX_RX = 0x23U,
This commit fixes the issue reported in #7285.
If the radio is unable to transmit, its a fatal error and can happen
both while joining or sending a normal packet. In the case of such
a catastrophy we ought to tell the application that this happened.
A fix for the radio driver will also be patched.
