67f196fcf8 configs/max32660-evsys: Added support for an SPI-based micro-SD card. Does not yet work (SPI hangs with no data transferred). 2018-11-30 15:12:38 -06:00

86a67fa3e8 Squashed commit of the following: 
arch/arm/src/max326xx/max32660/max32660_spim.c:  SPI0 master mode support is complete (sans DMA and completely untested).  configs/max32660-evsys/src:  Add framework for SPI support.

    arch/arm/src/max326xx/max32660/max32660_spim.c:  Fleshes out some of the data transfer logic.  More needs to be done.  Also removes leveraged DMA support.  It will be a long time (if ever) before DMA is supported.  No point in dragging all of that bogus logic around.

6d285cfed1 arch/arm/src/max326xx/max32660: Fix some confusion. SPI0 and SPI1 are not the same type of peripheral. SPI0 is SPI17Y; SPI1 is SPIMMS. Add basic SPI0 interrupt handling logic. 2018-11-29 18:32:40 -06:00

9203815e4c arch/arm/src/max326xx/max32660/max32660_spim.c: Add a little more SPI logic. Still not complete. 2018-11-29 15:38:13 -06:00

0841602739 Beginning of an SPI driver for the MAX32660. Incomplete. Does not even compile correctly yet. 
Squashed commit of the following:

    arch/arm/src/max326xx/max32660/max32660_spim.c: A few updates tot he SPI master driver.  Still incomplete and does not even compile.

    Update some comments

    arch/arm/src/max326xx:  Clean up some general build issues.  Still STM32 code posing as MAX32660.

    arch/arm/src/max326xx:  Starting SPI driver.  Initial commit is just the STM32 SPI driver with name changes.

8a99b5969e arch/arm/src/max326xx: Fixes UART interrupt problems. With these changes, the NSH configuration appears stable and is no longer conditioned on EXPERIMENTAL. 2018-11-29 07:50:45 -06:00

1710b96388 arch/arm/src/max326xx/max32660/max32660_serial.c: Using wrong register to check interrupt status. Still problems; I think we are not getting FIFO interrupts. 2018-11-28 17:44:20 -06:00

a6682a9bef Squashed commit of the following: 
arch/arm/src/max326xx and configs/max32660-evsys/src:  Fix some issues with GPIO setup of output pins.  Correct polarity of on-board LED output.  The on-board LED is now functional.

    arch/arm/src/max326xx: WFI instruction in IDLE loop seems to interfere with stability.  Commented out for now.  Needs to be investigated further.

d164a2cf5b Squashed commit of the following: 
arch/arm/src/max326xx:  Fixes for GPIO configuration problems and serial driver problems.  I now get the NuttShell prompt (if I also band on ENTER to force all of the characters out).  Progress, but not yet ready.

    configs/max32660-evsys:  Support CONFIG_BOOT_RUNFROMISRAM=y.
