43a88c1428 arch/arm/src/lpc54xx: Fix some LCD clocking. This eliminates the hang problem. That is now recognizable albeit corrupted data on the display. 2017-12-13 19:07:10 -06:00

b33d7eb59f arch/arm/src/lpc54xx: Add the ported LPC1788 LCD driver to use the LPC54xx pin definitions and SYSCON. 2017-12-12 12:53:33 -06:00

88834b6e50 arch/arm/src/lpc54xx: Add configuartion support and logic it all none, some, or all of the external RAM to the system heap. 2017-12-12 11:33:18 -06:00

63415f9fb1 arch/arm/src/lpc54xx: Clone the LPC1788 LCD driver. The LPC54628 LCD interface is identical. The initial commit is a brute force clone. It still needs review to make sure the LDC is appropriately enabled in the SYSCON and that clocking is provided. Also, extend the SPI 'skeleton' file so that has a place to support for SPI DMA and the SPI exchange method. 2017-12-12 10:13:21 -06:00

0cd87be495 arch/arm/src/lpc54xx: Correct the EMC divider register definition and one typo in the SDRAM setup. SDRAM is not fully functional on this board! 2017-12-12 08:24:57 -06:00

0508048291 configs/lpcxpresso-lp54629: Add logic to configure EMC pins. arch/arm/src/lpc54xx: Correct GPIO read/write logic. Update pin configuration for EMC pins. All should have the input file offset and fast slew rate. 2017-12-11 09:07:51 -06:00

df3404da09 arch/arm/src/lpc54xx: Various fixes for initial build of SDRAM support. Still unverified (but at least appears to be nonfatal). 2017-12-10 17:20:16 -06:00

8bc90a1899 This adds basic architectural support for the LPC546xx family and includes support for the LPCXpresso-LPC54628 board. The basic NSH port is almost complete... still lacking GPIO support and LED support. There are still no significant drivers available. 
Squashed commit of the following:

    arch/arm/src/lpc54xx:  Finish off some missing logic.  Complete now execpt for GPIO and LED support.
    arch/arm/src/lpc54xx:  Add lpc54_clrpend.c
    arch/arm/src/lpc54xx:  Serial driver is complete and compiles.
    arch/arm/src/lpc54xx:  Add beginning of a serial driver (still missing some logic)
    arch/arm/src/lpc54xx:  Fleshes out low level USART intialization.
    arch/arm/src/lpc546xx/Kconfig: Add hooks to integrate with common seril upper half.
    arch/arm/src/lpc54xx:  Beginning of USART console support.
    arch/arm/src/lpc54xx: Completes very basic clock configuration.
    arch/arm/src/lpc54xx:  Add clocking logic (still not complete)
    arch/arm/src/lpc54xx:  Beginning of PLL configuration logic.
    arch/arm/src/lpc54xx:  Fix a few things from first compile attempt.  Compilation cannot work until I at least finish the clock configuration logic.
    arch/arm/src/lpc54xx: Addes some SysTick logic.
    arch/arm/src/lpc54xx:  Completes basic startup logic (sans clock configuration) and interrupt configuration.
     arch/arm/src/lpc54xx:  Add generic ARMv7-M start-up logic (needs LPC54628 customizations); add emtpy file that will eventually hold the clock configuration logic.
    arch/arm/src/lpc54xx:  Add (incomplete) SYSCON register definition header file.
    arch/arm/src/lpc54xx:  Add FLEXCOMM header file.
    arch/arm/src/lpc54xx:  Bring in tickless clock logic from LPC43; configs/lpcxpresso-lpc54628: mount procfs if enabled.
    arch/arm/src/lpc54xx: Add RIT clock definitions; add SysTick initialization (not finished)
    LPC54xx and LPCXpresso-LPC54628: add more boilerplate files and stubbed out files.
    arch/arm/src/lpc54xx:  Add (incomplete) USART header file.
    Add another condition to a Kconfig; refresh a defconfig.
    arch/arm/src/lpc54xx/chip: Add LPC54628 memory map header files.
