Hi All,

We are using IMX8QM and facing issue in uboot to configure GPIO4_25 signal to default pulled down. Below is a

GPIO signal connected peripheral and want this signal default to pulled down in IMX uboot.

1. SC_P_QSPI1A_DATA1_LSIO_GPIO4_IO25

 

We have done changes in board_gpio_init function(board/freescale/imx8qm_mek/imx8qm_mek.c file) but the signal is still high.

But we need default GPIO4_25 signal configure low.

What is the default GPIO4_25 signal configurations?

How I can configure above GPIO4_25 signals default pulled down.

 

Please provide inputs to resolve this issue.

 

Thanks,

Hello,

Unfortunately, the product is still in preproduction and we cannot provide support for the product. For that, you need to go with your salesperson and he will help you with this problem. I apologize for the inconveniences this could give you.

Best Regards,

Diego.
