nuttx 中断栈配置

1、某块stm32单板跑nuttx系统，出现异常挂起，分析发现中断栈已经用完，需要调整中断栈大小

up_hardfault: PANIC!!! Hard fault: 40000000
up_assert: Assertion failed at file:armv7-m/up_hardfault.c line: 171 task: hpwork

2、单板的nuttx配置文件与中断栈相关的配置，需要调整CONFIG_ARCH_INTERRUPTSTACK配置项的大小

#
# Interrupt options
#
CONFIG_ARCH_HAVE_INTERRUPTSTACK=y
CONFIG_ARCH_INTERRUPTSTACK=750
CONFIG_ARCH_HAVE_HIPRI_INTERRUPT=y

CONFIG_ARCH_HIPRI_INTERRUPT=y

3、nuttx\arch\arm\src\armv7-m\gnu\up_exception.S文件里面分配了中断栈

/************************************************************************************
 *  Name: g_intstackalloc/g_intstackbase
 *
 * Description:
 *   Shouldn't happen
 *
 ************************************************************************************/
#if CONFIG_ARCH_INTERRUPTSTACK > 7
.bss
.global g_intstackalloc
.global g_intstackbase
.align 8
g_intstackalloc:
.skip (CONFIG_ARCH_INTERRUPTSTACK & ~7)
g_intstackbase:
.size g_intstackalloc, .-g_intstackalloc
#endif
      .end
