Hello,

 

      I need use some pins as LSIO function in M4 side,pin "SC_P_QSPI0A_SCLK  SC_P_ENET0_RGMII_TX_CTL  SC_P_ENET0_RGMII_RXC  SC_P_SPI3_CS0", I set this pads and resource to M4 side in SCFW and init GPIO used

GPIO_PinInit() function,but when I used GPIO_WritePinOutput() function pullup GPIO in driver,test the GPIO current,it is have no changed.

      Does M4 side can control LSIO GPIO?or only can control M40_GPIO?

 

 

Thanks
