This port was the joing effort of Janne Rosberg, Ivan Ucherdzhiev, and myself. I give credit to Ivan for the kill because he is the one to held on to the end. Squashed commit of the following: Author: Gregory Nutt <gnutt@nuttx.org> configs/imxrt1050-evk/scripts: Add section to linker script to handle the case where RAMFUNCs are enabled. RAMFUNCs appear to be enabled in the default configuration ... they probably should not be enabled. Author: Ivan Ucherdzhiev <ivanucherdjiev@gmail.com> arch/arm/src/imxrt: imxrt_lowputc.c is finished. Now everything needed for the initial port is done and ready for testing. arch/arm/src/imxrt: Add logic to imxrt_lowputc.c. Still incomplete. Author: Ivan Ucherdzhiev <ivanucherdjiev@gmail.com> arch/arm/src/imxrt: Add serial support. configs/imxrt1050-evk: Add linker script. Author: Gregory Nutt <gnutt@nuttx.org> arch/arm/src/imxrt: Add initial cut at imxrt_allocateheap.c Author: Ivan Ucherdzhiev <ivanucherdjiev@gmail.com> arm/arm/src/imxrt: Completes all definitions for PADMUX, CTLMUX, and IOMUX_INPUT and mapping tables on imxrt_gpio.c and imxr_iomuxc.c. arch/arm/src/imxrt/chip: Add definitions for IMXRT_PADCTL and IMXRT_PADMUX registers. Only the IMXRT_INPUT definitions in this commit. arch/arm/src/imxrt/chip: Add more IOMUXC register definitions. Author: Gregory Nutt <gnutt@nuttx.org> configs/imxrt1050-evk: Add STRIP definition to Make.defs. arch/arm/src/imxrt: Bring in i.MX6 memory configuration settings. arch/arm/src/imxrt: Remove call to non-existent imxrt_gpioinit() from imxrt_start.c. arch/arm/src/imxrt: Bring in incomplete imxrt_iomuxc.c file from i.mx6. arch/arm/src/imxrt: Add first cut at GPIO interrupt logic. arch/arm/include: Add definitions to support a second level of GPIO pin interrupts. Author: Janne Rosberg <janne.rosberg@offcode.fi> arch/arm/src/imxrt: Add imxrt_wdog.c/.h Author: Gregory Nutt <gnutt@nuttx.org> arch/arm/src/imxrt: Port SAMv7 interrupt logic to imxrt_irq.c. arch/arm/src/imxrt: More clarification of the start-up memory map. arch/arm/src/imxrt: Some mostly cosmetic clean-up to the imxrt_start.c file that was so rudely taken from the SAMv7. arch/arm/src/imxrt: Add imxrt_start.c. Initial commit is the the SAMv7 startup logic with name changes. Author: Ivan Ucherdzhiev <ivanucherdjiev@gmail.com> arch/arm/src/imxrt: Adds a few IOMUXC register definitions. Author: Janne Rosberg <janne.rosberg@offcode.fi> arch/arm/src/imxrt: Add imxrt_clockconfig.c/.h configs/imxrt1050-evk: Add clock configuration definitions to board.h arch/arm/src/imxrt: Fix CCM register name; Fix doubly defined in LPUART bit field. arch/arm/src/imxrt: Add analog defines to CCM register definition header file. Author: Gregory Nutt <gnutt@nuttx.org> arch/arm/src/imxrt: Bring in GPIO C files from i.MX6. Things are in disarray now because that GPIO logic depends on IOMUXC logic which is not yet in place. arch/arm/src/imxrt: Add a few more GPIO definitions to make the header file compatible with i.MX6 arch/arm/src/imxrt/chip: Add GPIO register definition file. Author: Janne Rosberg <janne.rosberg@offcode.fi> arch/arm/src/imxrt: Add DCDC register definitions. arch/arm/srch/imxrt: Add CCM register bit definitions Author: Gregory Nutt <gnutt@nuttx.org> Purely cosmetic arch/arm/src/imxrt: Add system reset controller register definition header file. Embarassingly trivial change left in compiler. arch/arm/src/imxrt: Finishes i.MX RT1050 LPUART register definition header file. arch/arm/src/imxrt: Beginning of an i.MX RT1050 LPUART register definition header file. Some trivial things Author: Janne Rosberg <janne.rosberg@offcode.fi> arch/arm/src/imxrt: Add imxrt_wdog.h arch/arm/src/imxrt: Add initial imxrt_ccm.h Author: Gregory Nutt <gnutt@nuttx.org> Trivial update to README. arch/arm/src/imxrt: The i.MX Rt implements 4 bits of interrupt priority, not two. Thanks, Janne. arch/arm/src/imxrt: Fix some initial compile issues. Still a long way from complete, but there is a buildable environment now for the imxrt1050-evk. configs/imxrt1050-evk: Add an initial NSH configuration for testing. configs/Kconfig: Hook the i.MX RT 1050 board configuration into the NuttX configuration system. configs/imxrt_evk: Add the framework for i.MX RT 1050 board support. arch/arm/src/imxrt: Bring in a few more files from LPC54xxx. arch/arm/src/imxrt: Bring in imxrt_clrpend() from the LPC54xxx. arch/arm/src/imxrt: Bring in Cortex-M7 SysTick setup from the SAMv7. arch/arm/src/imxrt: Add a few easy files. arch/arm/src/imxrt/chip: Add memory map header files. arch/arm/src/imxrt: A few basic files to start the port to the i.MX RT 1050.

#define NVIC_SYSH_PRIORITY_MAX 0x00 /* Zero is maximum priority */

/* If CONFIG_ARMV7M_USEBASEPRI is selected, then interrupts will be disabled
|
|
* by setting the BASEPRI register to NVIC_SYSH_DISABLE_PRIORITY so that most
|
|
* interrupts will not have execution priority. SVCall must have execution
|
|
* priority in all cases.
|
|
*
|
|
* In the normal cases, interrupts are not nest-able and all interrupts run
|
|
* at an execution priority between NVIC_SYSH_PRIORITY_MIN and
|
|
* NVIC_SYSH_PRIORITY_MAX (with NVIC_SYSH_PRIORITY_MAX reserved for SVCall).
|
|
*
|
|
* If, in addition, CONFIG_ARCH_HIPRI_INTERRUPT is defined, then special
|
|
* high priority interrupts are supported. These are not "nested" in the
|
|
* normal sense of the word. These high priority interrupts can interrupt
|
|
* normal processing but execute outside of OS (although they can "get back
|
|
* into the game" via a PendSV interrupt).
|
|
*
|
|
* In the normal course of things, interrupts must occasionally be disabled
|
|
* using the up_irq_save() inline function to prevent contention in use of
|
|
* resources that may be shared between interrupt level and non-interrupt
|
|
* level logic. Now the question arises, if CONFIG_ARCH_HIPRI_INTERRUPT,
|
|
* do we disable all interrupts (except SVCall), or do we only disable the
|
|
* "normal" interrupts. Since the high priority interrupts cannot interact
|
|
* with the OS, you may want to permit the high priority interrupts even if
|
|
* interrupts are disabled. The setting CONFIG_ARCH_INT_DISABLEALL can be
|
|
* used to select either behavior:
|
|
*
|

* CONFIG_ARCH_HIPRI_INTERRUPT | NO | YES
|

|
|
* ----------------------------+--------------+--------------+-------------
|
|
* | | | SVCall
|
|
* | SVCall | SVCall | HIGH
|
|
* Disable here and below --------> MAXNORMAL ---> HIGH --------> MAXNORMAL
|
|
