F28M36P63C2: ControlSUITE F28M36x_examples_Dual例程blinky问题

Part Number: F28M36P63C2

first question:

In M3's program: why the comment is:

// Give C28 control of Port C pin 6
GPIOPinConfigureCoreSelect(LED_0_BASE, LED_0_PIN, GPIO_PIN_C_CORE_SELECT);

Give C28 control of Port C pin 6, but in the source code it is:

#define LED_0_PERIPH SYSCTL_PERIPH_GPIOE

#define LED_0_BASE GPIO_PORTE_BASE

#define LED_0_PIN GPIO_PIN_7

It should be understood that it should be Give C28 control of Port E? I don't understand this. This is the first question.

second question:

In the C28 program, the code is indeed:

#define LED_0_DIR_REG GpioG1CtrlRegs.GPADIR.bit.GPIO31

#define LED_0_DAT_REG GpioG1DataRegs.GPADAT.bit.GPIO31

struct GPIOG1_DATA_REGS {

union GPADAT_REG GPADAT; // GPIO A Data Register (GPIO0 to

// 31)

May I ask this GPIO A Data Register (GPIO0 to 31) and the program in M3:

// Give C28 control of Port C pin 6
GPIOPinConfigureCoreSelect(LED_0_BASE, LED_0_PIN, GPIO_PIN_C_CORE_SELECT);

What is the relationship between the two? How does C28 control the GPIO of m3?

thank god for guidance

你好，问题1由于手头没有这款芯片的板子，我要去咨询一下英文E2E论坛的工程师。但是涉及时差，应该要今晚才会有回复，我会在下周一尽快更新。因此我建议你可以自己在板子上测试一下，看是代码有问题还是注释写错了。

关于GPIO分配的问题，如果C28x要配置GPIO，输入输出由C28x自己配置，模式应该是M3配置。

经过测试，应该是注释错误。
