Hi Expert!
We had testing on AM62x SK EVM for GPIO.
We followed https://dev.ti.com/tirex/explore/node?node=A__ANR3bSoQUtte3JSAV7ex0g__linux_academy_am62x__XaWts8R__LATEST for testing GPIO.
Used below images:
SDK 8.6 version. Default image for SD card boot.
Below is the console logs for boot and testing GPIO.
We just used 2-GPIO selected right now for testing and we did.
1: GPIO1_16
2: GPIO1_11
Below are gpio banks we got on console:
root@am62xx-evm:~# gpiodetect
gpiochip0 [omap-gpmc] (2 lines)
gpiochip1 [4201000.gpio] (24 lines)
gpiochip2 [600000.gpio] (87 lines)
gpiochip3 [601000.gpio] (88 lines)
gpiochip4 [1-0022] (24 lines)
We did some observation on GPIO1_16 & GPIO1_11
Please find below logs for that.

##############################################################################################################################
On above test from SW side we are able to change signal for those two GPIO's , But not from HW side.
We are not able to see any changes on Oscilloscope. Not able to see High and low signal on Oscilloscope for those GPIO's.
Is that the correct way or we are controlling wrong way?
If we are doing right way then why signal not changing on Oscillscope for AM62x SK?
FYI... on Oscilloscope we are able to see only LOW signal. not getting as HIGH even when we changed to high with above commands.
Thanks,
Suraj.
