I.MX6 ECSPI2 _SCLK

[khaledali]

I'm new using IMX6 processor and i need a fast solution
I'm using iMX6_Platform_SDK on a board , i understood the ECSPI module 2 but the output logic level is 1.8 V instead of 3.3 V
I need help to understand  how to make the output voltage 3.3 V ؟

Can you show your dts ecspi2 configuration?

[khaledali]

first of all thanks to your reply but

i have checked that in my board schematic all supplied voltages needed are connected to 3P3V

and i still have the problem

[igorpadykov]

also this may be caused by broken pad or board layout error

(some lines, like two outputs connected together).

Hi Khaled

one can check voltage of power supply which feeds that pads,

please use processor  datasheet, like Table 100. 21 x 21 mm Functional Contact Assignments

i.MX6DQ Datasheet (rev.4, 7/2015)

http://cache.freescale.com/files/32bit/doc/data_sheet/IMX6DQCEC.pdf

For i.MX6SL one can also check LVE bit in Pad Control Register (IOMUXC_SW_PAD_CTL_PAD_X_Y)

Best regards

igor
