Change RST of sim card slot failed...

[philipwang001]

kernel: linux4.1.15

platform: imx7d

Modified DTS file, to change "MX7D_PAD_EPDC_DATA10__SIM1_PORT1_RST_B" of sim1 to be other PINs, such as "MX7D_PAD_EPDC_DATA02__GPIO2_IO2". It did not work, WHY? Is this illegal?

Hi Wells

one can check if this pad is used by other module and in uboot.

Also one can check iomux settings with jtag to see which module owns pad.

Best regards
igor
