I.MX6 ECSPI2 _SCLK

khaledali — Thu, 21 Jul 2016 11:33:36 GMT

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 ؟

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

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

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

(some lines, like two outputs connected together).

Can you show your dts ecspi2 configuration?
