Hi,
I have a carrier board from trenz which is TE0703-05 which im using with a xilinx fpga module ( TE0720 SoC) . Now when I go for the serial communication through any serial communicator like Putty or tera term , I cannot make a connection with the board. It keeps asking for some linux username and password. My main goal is to take the input from the user to do certain things with fpga eg. changing the frequency or may be blinking an led. But I cannot establish the connection. Any help will be greatly appreciated. Thank You
Hello ritayandhara,
so you see no console prints when booting linux ? I recommend SmarTTY, it lists all devices, you only need to set the Baudrate to 115200. You should not be asked for credentials since the petalinux design has autologin activated, given you are using our latest test board design.
Are you using our latest reference design?

Im using the TE0720-03-1CF board. https://shop.trenz-electronic.de/de/TE0720-04-62I33ML-SoC-Modul-mit-AMD-Zynq-7020-2I-1-GByte-DDR3L-8-GByte-eMMC-4-x-5-cm-LP?path=Trenz_Electronic/Modules_and_Module_Carriers/4x5/TE0720/REV03/Documents
and I am using Xilinx Vivado 2024 edition. I just want to use the UART and the mini-usb port to blink an led in which the input has to be taken from the user through the keyboard. Now when I define pins into the constraint file, sometimes it cannot recognize the pin. Any help on how to proceed with this would be appreciated. Thank You again.
Hello ritayandhara,
you could start by connecting the two leds FLED1 and 2 to the VIO ip in your block design. Check whether you can turn them on and off from the hardware manager.
They go to the FPGA Pins U7 and R7 as can be seen in this spreadsheet:

Then you can connect them to an AXI GPIO IP and and control them from linux via your keyboard. You have to rebuild petalinux for that and generate the programming files
