NXP Real-Time Drivers (RTD)

https://www.nxp.com/design/automotive-software-and-tools/real-time-drivers-rtd:AUTOMOTIVE-RTD
|
|
|
|
Purpose:
|
|
Provides device header files and bare metal peripheral drivers for NXP S32 SoCs.
|
|
Zephyr shim drivers are built on top of these imported drivers to adapt the S32
|
|
drivers APIs to Zephyr APIs.
|
|
|
|
Description:
|
|
The "drivers" directory contains a sub-set of NXP S32 Real-Time Drivers used to enable
|
|
Zephyr support on NXP S32 SoCs. The "soc" directory contains SoC-specific default
|
|
configuration for these drivers, used at driver initialization time. The configuration
|
|
was generated with NXP S32 Design Studio for S32 Platform.
|
|
Care should be taken to retain local changes to the driver files that are documented
|
|
in Patch List section of this document.

Dependencies:
|
|
CMSIS header files

Patch List for S32K1:
|
|
- Define __MPU_PRESENT as 0 to be able to use NXP SYSMPU driver.
|
|
- Relocate uninitialized non-cacheable variables into .nocache section defined by Zephyr.
|
|
- Rename fields and macros of FTM device headers to allow compatibility with MCUX FTM driver.
|
|
- Rename fields and macros of FlexCAN device headers to allow compatibility with MCUX FlexCAN driver.
|
|
|
|
Patch List for S32K3:
|
|
- Relocate uninitialized non-cacheable variables into .nocache section defined by Zephyr.
|
|
- Clear the EOC flag before Adc_Sar_CheckAndCallEocNotification() is called to avoid the
|
|
race condition that prevents the next end of conversion callback to be executed, when
|
|
a conversion is started inside the previous end of conversion completed callback.
|
|
- Relocate Emios_Ip_paxBase array in Emios_Mcl_Ip.c to read only region as suppose to be.
|
|
- Remove 'u' suffix from macros so that they can be used with LISTIFY in shim drivers.
|
|
|
|
Patch List for S32Z/E:
|
|
- Relocate uninitialized non-cacheable variables into .nocache section defined by Zephyr.
|
|
- Remove 'u' suffix from macros so that they can be used with LISTIFY in shim drivers.
|
|
- Set the number of UART LINFlexD instances configured that bases on the number of
|
|
devicetree UART nodes enabled.
|
|
- Set the number of SPI instances configured that bases on the number of devicetree SPI
|
|
nodes enabled. Enable SPI slave support bases on CONFIG_SPI_SLAVE.
|
|
- Wrap the defined macros of each MRU instance base on devicetree MRU node so that they
|
|
is built when node enabled.
|
|
- Rename the PIT struct from TIMER to CHANNEL so that the MCUX PIT driver can be reused
|
|
for S32Z/E.
|
|
- Remove 'static inline' keywords from 'Netc_Eth_Ip_MSIX_Rx' function so that it can be
|
|
used as an extern function outside of the file declaration.
