- default value is the same as before patch
- system_stm32f3xx.c file is copied to family level with all other ST cube files
- specific clock configuration is now in a new file: system_clock.c (target level)
When we want to activate USE_FULL_ASSERT macro in STM32 CUBE, there is a
need to have the assert map to MBED.
The easiest way to have this definition in a single place for all STM32
HAL and LL files using it, is to add a specific header file where the
porting to MBED is done.
Before this patch, many warnings like below were generated
during compilation with ArmCC
[Warning] lwip_ethernet.h@57,0: #3135-D: attribute does not apply to any entity
This happens here as ``--gnu`` option of ArmCC is being used, which
enables the GNU compiler extensions that the ARM compiler supports.
This is solve by adding a extra check on __CCARM .
The USB ISTR register consists of a mix of bits that are
write-zero-to-clear and read only bits. As such, to clear a bit in
the ISTR, you should simply write the bitwise-NOT of the bit to clear.
Previously, the __HAL_PCD_CLEAR_FLAG() macro would do a bitwise-AND
with the ISTR register contents to clear a bit, but this could result
in another bit being inadvertently cleared if it is set by hardware
between the read and the write of the ISTR register.
Similarly, the USB endpoint registers have two bits that are
write-zero-to-clear, USB_EP_CTR_RX and USB_EP_CTR_TX, but the
PCD_CLEAR_RX_EP_CTR() and PCD_CLEAR_TX_EP_CTR() macros wrote back the
last read value for one of these bits when clearing the other bit.
This could result in inadvertent clearing of one of these bits if it
were set by the hardware between the read and the write. These macros
have now both been adjusted to always write one to the bit not being
cleared to prevent inadvertent clears.
In case of sequential transmit / receive, there is a need to:
- not use the reload option
- generate a new START on each new transaction
This applies to all HAL supporting the IP version V2.
