In previous commit, mstatus.mie was set when creating a new task

    Also, mstatus.mpp is set to machine mode in up_get_newintctx()

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

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
