6a3c2aded6 Fix wait loop and void cast (#24)
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

e4562fc538 This commit brings in support for the GAP8 architecture. The GAP8 is a 1+8-core DSP-like RISC-V MCU. Also included is support for the Gapuino GAP8 evaluation board.
Squashed commit of the following:

Author: Gregory Nutt <gnutt@nuttx.org>

    Completes review of configs/gapuino.
    arch/risc-v/include/gap8/chip.h:  Replace the moved chip.h header file with a dummy chip.h header file just to keep the system happy.
    Move include/gap8/chip.h to src/gap8/chip.h.  Internal details should not be exposed outside of arch/ and configs/.  Review all headers files in src/gap8
    Review of arch/risc-v/include.

Author: hhuysqt <hyq9606@126.com>

    corrected author and email
    Add app initialization, add signal support, cleanup irq context and configs
    fix some warnings
    gapuino initial port
    GAP8 initial port

9222f50e1c arch/: Make sure the up_irq_enable() is available on all architectures. I will not be able to test all of these new versions of this function so this may break things for awhile. 2018-06-06 09:25:40 -06:00

201a32cf8c Add support for the RISC-V architecture and configs/nr5m100-nexys4 board. I will be making the FPGA code for this available soon (within a week I would say). The board support on this is pretty thin, but it seems like maybe a good idea to get the base RISC-V stuff in since there are people interested in it. 2016-10-16 09:47:07 -06:00
