大家好， 我打算用bbb开发一个sysbios程序， 目前通过向导生成的程序编译下载正常。
增加一个timer0，和一个timer0isr后，程序编译正常，但是无法下载。
请问这是哪里出错了呢？
BBB的板子有进行初始化么？
请参考：http://www.deyisupport.com/question_answer/dsp_arm/sitara_arm/f/25/t/73955.aspx
我一开始没有进行初始化，以为在sysbios中会自动初始化。
后来加上时钟控制的初始化，发现timer2可以用，但timer3，timer6的寄存器还是不能访问。
这是cfg文件中的相关配置。
// install a "first function"var len = Startup.firstFxns.lengthStartup.firstFxns.length++;Startup.firstFxns[len] = '&dmTimerClkInitialization'
/* Create myTimer as source of Hwi */var Timer = xdc.useModule('ti.sysbios.hal.Timer');var timer2Params = new Timer.Params();timer2Params.instance.name = "timer2";timer2Params.period = 10000;Program.global.timer2 = Timer.create(2, "&myTimerFunc", timer2Params);Idle.idleFxns[0] = "&idleFxn";
这是c代码中的配置，
#define HWREG(x) (*((volatile unsigned int *)(x)))
/** @brief Base addresses of PRCM memory mapped registers */#define SOC_PRCM_REGS (0x44E00000)#define SOC_CM_PER_REGS (SOC_PRCM_REGS + 0)

HWREG(SOC_CM_PER_REGS + CM_PER_TIMER7_CLKCTRL) = 2; while(CM_PER_TIMER7_CLKCTRL_MODULEMODE_ENABLE != (HWREG(SOC_CM_PER_REGS + CM_PER_TIMER7_CLKCTRL) & 0x3));
/* Set DMTimer 2 clock enable bit */ HWREG(SOC_CM_PER_REGS + CM_PER_TIMER2_CLKCTRL) = 2; while(CM_PER_TIMER2_CLKCTRL_MODULEMODE_ENABLE != (HWREG(SOC_CM_PER_REGS + CM_PER_TIMER2_CLKCTRL) & 0x3));
HWREG(SOC_CM_PER_REGS + CM_PER_TIMER3_CLKCTRL) = 2; while(CM_PER_TIMER3_CLKCTRL_MODULEMODE_ENABLE != (HWREG(SOC_CM_PER_REGS + CM_PER_TIMER3_CLKCTRL) & 0x3));
HWREG(SOC_CM_PER_REGS + CM_PER_TIMER4_CLKCTRL) = 2; while(CM_PER_TIMER4_CLKCTRL_MODULEMODE_ENABLE != (HWREG(SOC_CM_PER_REGS + CM_PER_TIMER4_CLKCTRL) & 0x3));
HWREG(SOC_CM_PER_REGS + CM_PER_TIMER5_CLKCTRL) = 2; while(CM_PER_TIMER5_CLKCTRL_MODULEMODE_ENABLE != (HWREG(SOC_CM_PER_REGS + CM_PER_TIMER5_CLKCTRL) & 0x3));
HWREG(SOC_CM_PER_REGS + CM_PER_TIMER6_CLKCTRL) = 2; while(CM_PER_TIMER6_CLKCTRL_MODULEMODE_ENABLE != (HWREG(SOC_CM_PER_REGS + CM_PER_TIMER6_CLKCTRL) & 0x3));
}
代码执行后，发现timer2，4，5，7的初始化正常，
但是timer3，6初始化不正常。
CM_PER_TIMER3_CLKCTRL 0x00030002 This register manages the TIMER3 clocks. [Memory Mapped]
CM_PER_TIMER6_CLKCTRL 0x00030002 This register manages the TIMER6 clocks. [Memory Mapped]
这两个寄存器，已经通过写低位，使能，但是idle状态一直保持禁止状态，无法访问相关寄存器。
请问这个如何解决呢？
