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

454d59b049 sched/sched_foreach.c: sched_foreach() should not have to hold the critical section over the entire traversal. It should be acceptable to simply only the critical section while one entry is being processed (the caller can always call sched_foreach within a critical section is greater stability is needed. sched/sched_gettcb.c: Recent changes removed critical sections around calls to sched_gettcb.c. However, there is a very should sequence of instructions that actually does require the critical section. That short sequence no manages its own critical section. 2018-11-29 13:09:56 -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.

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.

d8cf3bfe25 Rethink some of the conditional logic of commit 1ac9558460: If the Critical Section Monitor enabled, that that platform-specific timer should be used to measure interrupt processing time, no matter what. 2018-11-26 12:18:58 -06:00

1ac9558460 sched/irq and sched/sched: Measurement of interrupt handler duration used to be available only in Tickless mode since it used the high resolution Tickless timer to measure interrupt time. This commit adds CONFIG_SCHED_IRQMONITOR_GETTIME which, if enabled, will force the interrupt duration caculation to use the same high-resolution, platform-specific timer as is used with the Critical Section Monitor. This leads to two improvements: (1) You can now measure interrupt duration in non-Tickless mode, and (2) in either mode, the interrupt duration and the critical section measures will use the same high-resulotion timer and should, therefore, never be any descripancy due to different clock sources. 2018-11-26 11:29:20 -06:00

0af39e1493 arch/: Update all _exit() implementations for all architectures so that they correctly called the scheduler instumentation layer for the new task that runs when the old one exits.
