Issue originally reported on mbed site here:
https://developer.mbed.org/questions/5695/FRDM-KL05z-hardfault-when-compiled-with-/
The RAM base address was incorrectly set to the beginning of RAM
instead of at a 0xC0 byte offset to reserve room for the interrupt
vectors. Without this fix, the global variables and the interrupt
vectors were occupying the same space in RAM once the user enabled the
timer interrupt.
The user who originally reported the issue on the mbed site has tested
this fix and verified that it corrected the hard fault issue that they
were encountering.
- Change default setting of CMSIS-RTOS RTX for Cortex-A9 to align with Cortex-M.
- Change the interrupt priority of Ether driver to align with other drivers.
Changes as below.
-I2C
Change communication wait time and Frequency accuracy improvement of I2C.
- Frequency accuracy improvement
- Changed the wait time between one communication completed and the next communication start.
The wait time will be Low clock width by this changing.
-PWM
Modify processing of pulsewidth() of PWM
- Modify processing of pulsewidth() to match the specifications of the RZ_A1H.
-SPI
Fixed a bug that SPI driver is not able to communicate when transfer bit length is 16bit or 32bit.
- Frequency accuracy improvement
- Modify transfer processing when transfer bit length is 16bit or 32bit.
-Serial
Change the reference register macro of Serial
- Change the reference register macro to align with other driver codes.
Original STM32Cube F4 driver sets SYSCLK for STM32F429 to 16MHz. This
adds a 168MHz and 180MHz configuration to system_stm32f4xx.c generated
by STM32CubeMX code generator. The rtos clock configuration is changed
too. In singletest.py run everything is OK.
- Changing original STM Cube Driver to call _start instead of main to
initialise the rtos when using it. Without using rtos the behavior is
the same as before.
- Adding DISCO_F429 to rtos
- Adding targets to RTOS_xx tests.
- All tests are OK. Tested with Nucleo and Disco boards. Not tested with
MDOT_F4 but that uses the same hal like nucleo_f411.
Fix a bug as below.
- Period can not be changed.
Restructions: 1. The upper limits is 491us
2. Change all period of the same channel when changing period.
Fix some bugs of Serial as below.
- TX/RX terminal of XBee(P7_4, P7_5) setting is reverse.
- P5_6 and P5_7 terminals can not be used.
- Tx interrupt will not occur at the right timing.
- There are no settings of WIFI Module terminals(P11_10,P11_11).
- There are no settings of Xbee Module terminals(P6_6,P6_7).
