C28xx: Error: (Error -154 @ 0x0) One of the FTDI driver functions used to write data returned bad status or an error. (Emulation package 5.1.232.0)
程序如下:
void main(void)
{
Gpio_select();
DINT;
InitPieCtrl();
IER = 0x0000;
IFR = 0x0000;
// 初始化PIE中断向量表,并使其指向中断服务子程序(ISR)
// 这些中断服务子程序被放在了DSP280x_DefaultIsr.c源文件中
// 这个函数放在了DSP2833x_PieVect.c源文件里面.
InitPieVectTable();
// 步骤 4. 初始化片内外设:
// 这个函数可以在DSP280x_CpuTimers.c源文件中找到
// InitCpuTimers(); // 这个例子仅初始化了Cpu定时器
// 步骤 5. 用户特定的代码
for(;;)
{
GpioDataRegs.GPCSET.bit.GPIO64=1;
delay_loop();
while(1);
}
}
//延迟子函数
void delay_loop()
{
Uint32 i;
Uint32 j;
for(i=0;i<32;i++)
for (j = 0; j < 80000; j++) {}
}
//GPIO初始化函数
void Gpio_select(void)
{
EALLOW;
GpioCtrlRegs.GPAMUX1.all = 0x00000000; // All GPIO
GpioCtrlRegs.GPAMUX2.all = 0x00000000; // All GPIO
GpioCtrlRegs.GPBMUX1.all = 0x00000000; // All GPIO
GpioCtrlRegs.GPBMUX2.all = 0x00000000; // All GPIO
GpioCtrlRegs.GPCMUX1.all = 0x00000000; // All GPIO
GpioCtrlRegs.GPCMUX2.all = 0x00000000; // All GPIO
GpioCtrlRegs.GPADIR.all = 0xFFFFFFFF; // All outputs
GpioCtrlRegs.GPBDIR.all = 0xFFFFFFFF; // All outputs
GpioCtrlRegs.GPCDIR.all = 0xFFFFFFFF; // All outputs
EDIS;
}

主函数就一个bit
