Linux/AM5728: GPIO, UART and I2C operations in AM572X EVM

Part Number:AM5728

Tool/software: Linux

Hi,

I am new to AM572x EVM. Previously I worked with Beaglebone Black and interfaced GPIOs, UART and I2C.

But I think , it is slightly different for AM572x EVM.

Please refer me some wiki or guides , for interfacing GPIOs, UARTs and I2C inAM572x.

Now I am able to communicate with AM572x EVM through ssh(Ethernet port), minicom(debug port).

And I can run some simple applications   - helloworld.

First I tested GPIOs with the same code which is working well in Beaglebone black board.

With this software, the folder /sys/class/gpio/gpioxx folders are getting created. The file "value" is getting updated as in the software.

But this value is not appeared in the pin output.

Shall I change the am57xx_evm.dts file to make GPIOs, UART and I2C working for AM572x?

Thanks in advance for the help.

Thanks and Regards,
