i.MX8QXP M4 config GPIO question

xu_ji1 — Thu, 05 Sep 2019 11:08:17 GMT

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

Hi Xu,

I’m afraid that i.MX8QXP is still on preproduction and no additional information/support could be provided yet. For further assistance, please contact with your Sales/FAE.

Hope this will be useful for you.
Best regards!
