b3d609959c arch/arm/src/s32k1xx/hardware/s32k1xx_flexcan.h: Add an incomplete FlexCAN register definition header file. Still missing some bitfield definition. Also updates some README files. 2019-08-23 07:35:49 -06:00

c6026d7500 With these changes the S32K146EVB minimal NSH is function. Only verifed while running from SRAM.
arch/arm/src/s32k1xx/s32k1xx_lowputc.c:  Fix a typo that prevented LPUART1 from working.
    arch/arm/src/s32k1xx/s32k1xx_periphclocks.c and related files:  Fix yet another case of confusion between pre-decremented and non-decremented divider values.  Enforce the rule that dividers are not decremented until the moment they are written into registers.
    arch/arm/src/s32k1xx/s32k1xx_clockconfig.c:  Fix another problem related to whether a divider is pre-decremented or not.  The answer must be the divder values are never pre-decremented.  They are decremented just before being written to hardware.
    arch/arm/src/s32k1xx/s32k1xx_clockconfig.c:  Clean up some bad conditional logic.  Precedence of operators problem.
    boards/arm/s32k1xx/s32k118evb:  Add support for execution out of SRAM.  This is helpful for bringup when you want to avoid putting a lethal image in FLASH.
    arch/arm/src/s32k1xx/s32k1xx_clockconfig.h:  Remove crystal frequency, it is not used.
    arch/arm/src/s32k1xx/s32k1xx_wdog.h:  Fix a typo in a register name.i
    boards/arm/s32k1xx/s32k*evb/configs/nsh/defconfig:  Create Motorola SREC output format.

39d1a02c6d This commit adds support for the S32K146EVB
Squashed commit of the following:

    s32k1xx/s32k146evb/scripts/flash.ld:  Update the linker script for the S32K146.
    boards/:  Hook the S32K146EVB into the configuration and build system.
    s32k146_clockconfig.c:  Add S32K146 clock configuration.
    boards/arm/s32k1xx/s32k146evb/src/s32k146_periphclocks.c:  Update peripheral clocking for the S32K146.
    arm/s32k1xx/s32k146evb:  Initial support fo S32K146EVB.  Starting point is just the S32K118EVB with name changes.

db0641556e boards/arm/s32k1xx/s32k118evb: Implement board support for LEDs and buttons. This is taken from the Freedom-K66f with has the same LED and button configuation as the S32K116EVB and uses the same GPIO IP.
boards/arm/s32k1xx/s32k118evb/include/board.h:  Add LPUART0 pin disambiguation.

arch/arm/src/s32k1xx/hardware:  Add pin mux definitions for S32K116, 118, 142, 144, 146, and 148.

arch/arm/src/s32k1xx/s32k1xx_pin.c and .h:  Add support for PIDR register that disables a gneral purpose pin from acting as an input.

arch/arm/src/s32k1xx/s32k1xx_pin.c and .h:  The device does not support slew rate controls or open drain (on all the pins).  Only pins that are configured for a protocol that requires open-drain (e.g;, LPI2C, LPUART single-wire) will work in open-drain mode.

8987a9e374 This commit adds initial board support for the NXP S32K118EVB. This configuration is intended, initially, to support development of the architecture support. This is VERY much a work in progress and you should not use this configuration unless you are interested in assisting with the bring-up.
Squashed commit of the following:

    boards/arm/s32k1xx/s32k118evb/configs/nsh:  Add a basic NSH configuration.
    boards/arm/s32k1xx/s32k118evb/scripts:  Add linker scripts and Make.defs.
    configs/:  Hook the S32K118EVB board into the configuration system.
    boards/arm/s32k1xx/s32k118evb:  Add initial support for the NXP S32K118EVB.
