TMS320F280025: 使用CLB配置GPIO无法输出

Part Number: TMS320F280025

hi ,我使用syscfg配置CLB,目的是让GPIO5输出与GPIO4相反的电平;但并未成功,以下是我的配置

1.GPIO4作为输入,通过INPUTXBAR连接到XBAR_INPUT7

2:通过CLBXBAR 将XBAR_INPUT7连接到AUXSIG0

3.使能CLB模块,将CLB X-BAR AUXSIG0作为input0

4,配置TILE LUT0 输入取反

5,配置output LUT4,输出LUT0的输出

6,配置OUTPUTXBAR 将CLB1 OUT4连接到GPIO5

7,初始化Board_init和CLB

8.此时GPIO4为低电平,理论上GPIO5应为高电平但是GPIO并无动作;

我想问下是我配置出了问题吗,烦请解答,谢谢!
