avoid to conflicting types for 'uint32_t' error.
2018-10-03 23:08:17 +08:00
SASANO Takayoshi 54f23a4293 avoid to conflicting types for 'uint32_t' error.
already uint32_t is defined at components/libc/compilers/minilibc/stdint.h.

there is two ways to solve, using <stdint.h>/uint32_t pair or
<rtthread.h>/rt_uint32_t pair.

I choose former because this code belongs to C compiler, not RT-Thread system.

2) mmu_setmtt抽取为函数mmu_setmtts,并增加RT_WEAK.mmu_setmtts此处作为示例函数.实际用户板子可在bsp中重新实现该函数.可在rt_components_board_init函数前调用rt_hw_mmu_init

Adrian Huang 4222677933 [libcpu][am335x] Fix the booting failure when enabling MMU
Since the 16 domains are configured as the client domains in
mmu_setttbase(), a Permission fault is generated if the XN bit
(Execute-never) is set in the short-descriptor translation table
(for section and supersection). This leads to the booting failure
when enabling MMU for beagleboard bsp. Here is log:

This commit removes the XN bit configuration in the section of the
short-descriptor translation table. The OS can be booted successfully
with applying this commit.

Grissiom 24fc6e6ebb rm48x50: VFP lazy stacking
You need to turn on RT_VFP_LAZY_STACKING in rtconfig.h. By default, RTT
will turn on VFP for all threads and stack all the VFP registers. When
doing lazy stacking, VFP will only be turned on for the thread who
issued VFP instructions.

Currently, if a thread turned on VFP, it cannot be turned off. RTT will
never know what time the thread doesn't need VFP any more. The thread
might could turn off the VFP for it self in proper time.

We currently only support building with CCS and SCons is not using.
bsp/rm48x50/HALCoGen/HALCoGen.{hcg,dil} is the HALCoGen project file.
You may need to regenerate the source file as you like, providing that:

    1, IRQ is in Dispatch Mode and the table entry is IRQ_Handler. The
    channel 5 in enabled and connected to IRQ.

    2, RTI driver is enabled and compare3 source is selected to counter1
    and the compare3 will generate tick in the period of 10ms. This
    value is coresponding with RT_TICK_PER_SECOND in rtconfig.h.

In CCS, you need to create a new CCS project and create link folders
pointing at bsp/rm48x50, libcpu/arm/rm48x50 and src/, include/. Remember
to add the include path to the Build Properties.
