ff1e6a66e9 configs/metro-m4: Fix problem with SysTick timer running too fast. This turned out to be a dumb typo in board.h that was providing the wrong CPU frequency to the SysTick setup logic. 2018-09-02 07:31:16 -06:00

aee1c39eab configs/metro-m4: Fix RxD interrupt pin selection. The number SERCOM interrupts do not refer to PAD numbers, but to bit positions in the INFLAG register (very tiny footnote in the data sheet). With with final fix, the basic NSH configuration appears fully functional. 2018-09-01 15:29:22 -06:00

6ada0e10ba configs/metro-m4: Fix RxD PAD selection. Add a configuration option to use OSCULP32K instead of XOSC32K. 2018-09-01 14:38:19 -06:00

438f6a866b arch/arm/src/samd5e5/: Some failed attempts to get the USART SERCOM initialized. Still worthy changes although they do not solve the problem. 2018-08-31 16:18:10 -06:00

ff906b0bef arch/arm/src/samd5e5: Updates to clock configuration from initial testing. With these changes the boot up gets through clock configuration but hangs in the low-level USART configuration before completing the boot. 2018-08-31 09:58:53 -06:00

a9d713bbcc This is the initial commit the port to the SAMD5x/E5x MCU family and also support for the Adafruit Metro M4 board. It port is untested and unfinished. It currently will not even link due to some missing clock related logic. 
Squashed commit of the following:

    arch/arm/src/samd5e5: Clean-up EIC logic.
    arch/arm/src/samd5e5:  Fix some compilation issues; Still issues with the EIC logic from samd2x.
    arch/arm/src/samd5e5:  Fix some compilation issues; bring in some EIC logic from samd2x.
    arch/arm/src/samd5e5:  Add NVMCTRL header file, fix some compiler problems, misc. clean-up.
    configs/metro-m4:  Add LED support.
    arch/arm/src/samd5e5:  Bring in SAML21 clock configuration.  This is a WIP; it cannot possible even compile yet.
    arch/arm/src/samd5e5:  Leverage Cortex-M4 interrupt and SysTick logic from the SAM3/4.
    arch/arm/src/samd5e5: Add SERCOM utility function.
    arch/arm/src/samd5e5:  Bring all SERCOM USART logic from SAMD2L2 to SAMD5E5.  This is a brute coy with nothing more than more that name changes and extension from 5 to 7 SERCOMs.
    arch/arm/src/samd5e5: Add sam_config.h header file
    arch/arm/src/samd5e5/:  Add Generic Clock (GCLK) utility functions.
    arch/arm/src/samd5e5:  Add EVSYS register definition file
    arch/arm/src/samd5e5 and configs/metro-m4:  Use SERCOM3 for the Arduino serial shield as console.
    arch/arm/src/samd5e5/chip:  Add SERCOM USART, SPI, I2C master, and slave register defintions header files
    arch/arm/src/samd5e5/chip:  Add AES, PM, TRNG, and WDT header files.
    arch/arm/src/samd5e5/chip:  Add pin multiplexing header files.
    Various fixes to configuration system; fix metro-m4/nsh defconfig file.
    configs/metro-m4:  Add initial support for the Adafruit Metro M4 board.
    arch/arm/src/samd5e5:  Add peripheral clock helpers.
    arch/arm/src/samd5e5/chip:  Add PAC register definition header file.  Fix some errors in the memory map header file.
