d0c58fffb3 Kinetis:Refactor clocking in kinetis_usbdev 
1) Removed SIM_CLKDIV2[USBFRAC, USBDIV] setting as it is now
     done in kinetis_clockconfig
  2) Use BOARD_USB_CLKSRC to select the clock source to the
     USB block
  3) Removed warning
  4) Removed CONFIG_TEENSY_3X_OVERCLOCK from the driver as
     the board.h will now provide BOARD_SIM_CLKDIV2_USBDIV
     and BOARD_SIM_CLKDIV2_USBFRAC to the kinetis_clockconfig

1c518b223d Kinetis:Add the configuring SIM_CLKDIV2[USBFRAC, USBDIV] in kinetis_clockconfig 
If a board.h provides BOARD_SIM_CLKDIV2_FREQ it will configure the
  SIM_CLKDIV2 based on the additional provided
  BOARD_SIM_CLKDIV2_USBFRAC and BOARD_SIM_CLKDIV2_USBDIV

  The reason for doing this globaly is that the output the
  SIM_CLKDIV2 divisor may be also used for other IP blocks in
  future configurations (as is done for SIM_CLKDIV3)

41e3d9f174 Kinetis:Refactor you use SIM_SOPT2_PLLFLLSEL, added warning 
The warning has been added because: SIM_SOPT2_PLLFLLSEL
  is a clock selection that may feed many clock subsystem:
   USB, TPM, SDHCSRC, LPUARTSRC. Therefore, there needs to
  be a global board level setting to select  the source for
  SIM_SOPT2_PLLFLLSEL and then  derive all the  sub selections
  and proper fractions/divisors for each modules clock.

8525c266a1 Created a kinetis PMC versioning scheme pulled in by Kinetis chip.h 
The motvations is to version the IP blocks of the Kinetis
     K series family of parts.

     This added versioning and configuration features for the
     Kinetis PMC IP block.

     It is envisioned that in the long term as a chip is added.
     The author of the new chip definitions will either find
     the exact configuration in an existing chip define and
     add the new chip to it Or add the PMC fature configuration
     #defines to the chip ifdef list in
     arch/arm/include/kinetis/kinetis_pmc.h  In either case the
     author should mark it as "Verified to Document Number:"
     taken from the reference manual.

     The version KINETIS_PMC_VERSION_UKN has been applied to
     most all the SoCs in the kinetis arch prior to this commit.

     The exceptions are the CONFIG_ARCH_CHIP_MK60FN1M0VLQ12,
     CONFIG_ARCH_CHIP_MK20DXxxxVLH7 All K64 and K66 have ben

ddd1f8c507 Kinetis SDHC - Enable clock after selected 2017-02-13 13:24:47 -10:00
Manohara HK
b154531838 I found an issue inside the cp15_coherent_dcache function in file, arch/arm/src/armv7-r/cp15_coherent_dcache.S. 
The "mcr CP15_BPIALLIS(r0)" instruction is used for invalidating entire branch predictor.  But the problem is, since this is the generic code and can be called on any armv7-r architecture based CPU's.  It is a problem, if this instruction is called in uni processor configuration. Because, BPIALLIS (c7, 0, c1, 6) instruction is only added as part of the "Multiprocessing Extensions" (As per ARM® Architecture Reference Manual /ARMv7-A and ARMv7-R edition)

So in my opinion, this instruction should be under SMP configuration. In non-SMP configuration this instruction could become undefined.

9bbd98580b Created a kinetis MCG versioning scheme pulled in by Kinetis chip.h 
The motvations is to version the IP blocks of the Kinetis
   K series family of parts.

   This added versioning and configuration features for the
   Kinetis MCG IP block.

   It is envisioned that in the long term as a chip is added.
   The author of the new chip definitions will either find
   the exact configuration in an existing  chip define and
   add the new chip to it Or add the MCG feature configuration
   #defines to the chip ifdef list in
   arch/arm/include/kinetis/kinetis_mcg.h  In either case the
   author should mark it as "Verified to Document Number:"
   taken from the reference manual.

   The version KINETIS_MCG_VERSION_UKN has been applied to
   most all the SoCs in the kinetis arch prior to this commit.

   The exceptions are the CONFIG_ARCH_CHIP_MK60FN1M0VLQ12,

efb86382c3 SMP: Back out deferred IRQ locking. This was accidentally merged into master and it looks like it is going to be more work than I thought to get it working again. Changes will go to the irqlock branch. 2016-12-24 19:53:37 -06:00

c83da3c48f Remove minnsh configurations and support logic: up_getc() and lowinstream. 
This was an interesting exercise to see just how small you could get NuttX, but otherwise it was not useful:  (1) the NSH code violated the OS interface layer by callup up_getc and up_putc directly, and (2) while waiting for character input, NSH would call up_getc() which would hog all of the CPU.  NOt a reasonably solution other than as a proof of concept.

a36ed28790 SAMV7: MCAN: Prevent Interrupt-Flooding of ACKE when not connected to CAN-BUS. An Acknowledge-Error will occur every time no other CAN Node acknowledges the message sent. This will also occur if the device is not connected to the can-bus. The CAN-Standard declares, that the Chip has to retry a given message as long as it is not sent successfully (or it is not cancelled by the application). Every time the chip tries to resend the message an Acknowledge-Error-Interrupt is generated. At high baud rates this can lead in extremely high CPU load just for handling the interrupts (and possibly the error handling in the application). To prevent this Interrupt-Flooding we disable the ACKE once it is seen as long we didn't transfer at least one message successfully. 2016-12-13 11:22:54 -06:00

dd309ad9e8 I was wrong - the original commit was correct. Assume a write op on the last word: address of 0xxxxxfe and count of 2. It is a valid operation and address+count is == STM32_FLASH_SIZE - so that is OK 2016-12-08 21:14:31 +00:00
