For general structure and of the reference design, see Project Delivery

...

...

TE Scripts are only needed to generate the vivado project, all other additional steps are optional and can also be executed by Xilinx Vivado/SDK GUI.  For currently Scripts limitations on Win and Linux OS see: Project Delivery Currently limitations of functionality

...

1. Connect JTAG and power on the carrier with module
2. Open Vivado Project with "vivado_open_existing_project_guimode.cmd" or if not created, create with "vivado_create_project_guimode.cmd"
3. Type on Vivado TCL Console: TE::pr_program_flash_binfile -swapp u-boot
   Note: To program with SDK/Vivado GUI, use special FSBL (zynqmp_fsbl_flash) on setup
            optional "TE::pr_program_flash_binfile -swapp hello_te0726" possible
4. Copy image.ub on SD-Card
   • For correct prebuilt file location, see <design_name>/prebuilt/readme_file_location.txt
5. Insert SD-Card

...

Xilinx Zynq devices in CLG225 package do not support SD Card boot directly from ROM bootloader. Use QSPI for primary boot and SD for secondary boot (ubootu-boot)

JTAG

Not used on this Example.

...

1. Prepare HW like described on in section Programming
2. Connect UART USB (most cases same as JTAG)
3. Insert SD Card with image.ub
4. Power On PCB
   Note: 1. Zynq Boot ROM loads FSBL from QSPI into OCM, 2. FSBL loads U-boot from QSPI into DDR, 3. U-boot load Linux from SD into DDR

...

1. Open Serial Console (e.g. putty)
   
   1. Speed: 115200
   2. COM Port: Win OS, see device manager, Linux OS see  dmesg |grep tty  (UART is *USB1)
2. Linux Console:
   Note: Wait until Linux boot finished For Linux Login use:
   
   1. User Name: root
   2. Password: root
3. You can use a Linux shell now.
   1. I2C 1 Bus type: i2cdetect -y -r 5
      Bus 0...5 possible
   2. ETH0 works with udhcpc
   3. USB: insert USB device
