    Where is TCL file for microzed ZYNQ-7010?


      I am trying to use xilinix JTAG to load uboot.elf on to the RAM.

      However, I need the tcl file to preset the processor settings.


      source "tcl file" so that it can load my uboot.elf.

          All build artifacts would be present under the project build folder on your hard drive.

            What you need is the Zynq First Stage Boot Loader (FSBL) elf file.  This, along with the u-boot elf file and PL bitstream (if you have one), can be used to boot via JTAG or can be packaged into a boot.bin file for booting via SD card, etc.  A good place to start with learning the flow of booting u-boot and Linux is one of Avnet's posted PetaLinux BSPs for the MicroZed SOMs.  Xilinx User Guide 1144 is an excellent resource developing with PetaLinux.

                I did that but I can't see anything on the console.


                Serial console is blank when I write fsbl.elf to RAM using JTAG?


                I have generated fsbl.elf using Symbols - FSBL_DEBUG_INFO.

                I do see that if I create a boot gen image using this FSBL.elf and place in SD card.

                And then if I change the jumper to SD card mode, I see FSBL prints on the console.

                However, I don't see prints coming on to the serial port if I do load the

                fsbl.elf using JTAG and JTAG mode.
