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,
I modified RAM size of ARMCC compiler for GR-LYCHEE.
In case of GR-LYCHEE, RAM size is 3M Byte(including Non-Cache area), but there was a typo at MACRO definition.
The mainly changes is below:
- Update scatter file, linker file for bootloader support
- Update the file for RZ/A1 serial flash boot loader
- Add "device name" and "bootloader_supported" in targets.json
The mainly changes is below:
- Add flash_api.c
- Add the definition of SPI multi I/O Bus controller that is used for flash access
- Add "FLASH" as device feature
- Add the macro regarding information of the incorporated Flash
- Add the processing to expand code to RAM
1. Add the IVT header to the binary as this is required for boot up
This was earlier added by the DAPLink firmware. As it is no longer
handled in DAPLink, the header needs to be added inside mbed.
2. Update drivers

New changes to Mbed error reporting in 5.9 exposed bug in SPI
driver where an instance was uninitialized twice which triggered
an ASSERT.
This fix keeps track of which instance has been initialized and
only calls uninit when it is safe.
Set the second highest user level, leaving the highest for UART (we are having constant overflows) and two levels below for everything else.
This should increase the timer accuracy.
RTC counter is 24-bit. Upper layer handles counter size and wraps ticks count when interrupt is to be fired before passing it to common_rtc_set_interrupt(), but for consistency and safety reasons we can wrap it again in the NRF driver.
There are cases where a call hal_deepsleep would overflow the idle task
stack, especially in developper or debug profile.
In order to avoid this case, we split ForceClockOutofDeepSleep
into two separate functions the two structure RCC_ClkInitStruct and
RCC_OscInitStruct are not allocated at the same time.
