3a029ed185 Merged in hg42/nuttx/lpc17-disable-FDR-2 (pull request #596) 
disable LPC17 FDR when not used (second fix)

if a boot loader sets the fractional divider (FDR) the baud rate in
nuttx will be wrong (multiplied by this fraction).

This also has to be added to lpc17_lowputc.c

Unfortunately the constant used for shifting the bits was wrong in the header file, so it took some time to realize this...

da051fb3d9 Merged in hg42/nuttx/lpc17-disable-FDR (pull request #591) 
disable LPC17 FDR when not used

* disable LPC17 FDR when not used

    if a boot loader set the fractional divider (FDR) the baud rate in
    nuttx will be wrong (multiplied by this fraction).

    So if it is not used, it should be disabled.

    LPC176x docs say:
    "
    DIVADDVAL Baud-rate generation pre-scaler divisor value.
    If this field is 0, fractional baud-rate generator will
    not impact the UARTn baudrate.

    MULVAL Baud-rate pre-scaler multiplier value.
    This field must be greater or equal 1 for UARTn to operate properly,
    regardless of whether the fractional baud-rate generator is used or not.
    "

    So DIVADDVAL is set to 0 and MULVAL is set to 1.

* symbols found and added

b884fb9fed sched/sched: Extend the last global lock change to work with the lc823450-xgevk which does not support the atomic fetch add but does support disabling interprocessor interrupts.

37c9b3d54a sched/sched: Implements a global scheduler lock capability as part of SMP support. This allows the scheduler to be locked with no knowledge or access to the TCB of the currently running task. This is necessary because accessing the TCB of the currenlty running task is, itself, a non-atomic operation. This global scheduler lock cpability was add just to support that atomic access to the TCB. 2018-02-05 13:12:36 -06:00

cbd8fa31d1 configs/stm32f429i-disco: Separate SPI4 from MTD init. I was trying to attach a non-MTD peripheral to an STM32F429I Discovery Board's SPI4 port and was hitting compilation problems, since CONFIG_MTD and thus 'struct mtd_geometry_s' was not defined. This patch separates SPI4 initialization logic from MTD initialization logic. 2018-02-05 06:35:40 -06:00

c8a372702a sched/sched: SMP: Fix this_task() to be an atomic operation. In the previous implementation, this_task() was defined in sched.h by using just a macro current_task(this_cpu()). However, I found that this is not atomic and actually sometimes switching CPU happened in executing the macro when we tested audio steaming plus executing commands via telnet. This change resolves this issue by implementing atomic this_task()in sched_thistask.c which is newly introduced. 2018-02-04 16:59:09 -06:00
