Support Request for TE0808-05-BBE81-E – VIO and Debug Hub Detection Issues in Vi

[cristina]

Hi everyone ,

I'm facing an issue with the TE0808-05-BBE81-E board (Zynq UltraScale+ XCZU15EG-1FFVC900E, 4GB DDR4) and I would appreciate any help or guidance.

System configuration:
Board: TE0808-05-BBE81-E
Processor: Xilinx Zynq UltraScale+ XCZU15EG-1FFVC900E
Memory: 4 GB DDR4 SDRAM
Development environment: Vivado 2022.1

Workflow followed:
1-I downloaded the Starter Kit project for the TE0808 from the official Trenz Electronics website and imported it into Vivado.
2-Connected to the hardware using:
3-open_hw_manager
4-connect_hw_server -url localhost:3121 -allow_non_jtag
5-Detected the device with get_hw_devices xczu15_0
6-Generated the bitstream (zusys_wrapper.bit) and .ltx file (zusys_wrapper.ltx) through the implementation (impl_1)
7-Programmed the device using program_hw_devices

Main issue:
Although the bitstream is successfully loaded (DONE status = 1), Vivado does not detect the VIO visualization cores—specifically the vio_general core. As a result, I am unable to visualize any signals in the Hardware Manager, which is a critical part of my HIL validation process.
Given that I am using the official Starter Kit project downloaded from the Trenz Electronics website, I would expect it to work out-of-the-box.

            Resolution:
            1. Make sure the clock connected to the debug hub (dbg_hub) core is a free running clock and is active.
2. Make sure the BSCAN_SWITCH_USER_MASK device property in Vivado Hardware Manager reflects the user scan chain setting in the design and refresh the device.  To determine the user scan chain setting in the design, open the implemented design and use 'get_property C_USER_SCAN_CHAIN [get_debug_cores dbg_hub]'.
            For more details on setting the scan chain property, consult the Vivado Debug and Programming User Guide (UG908).

Has anyone faced this issue when using the official Starter Kit project from Trenz Electronics?
Is there a known fix or additional configuration required for proper VIO detection on the TE0808 board?

I'm attaching the block design diagram for reference.
Any help would be highly appreciated!

Thanks in advance!

your report already says what the likely issue is, namly if the VIO core does not see a free running clock, it will not be detected. So it is a clocking issue.

Hi,
bitstream itself does not configure PS. This will be done by FSBL, not with bitstream.This is the reason why you didn't see any VIO core, because CLK is missing. In case you want to use PS-PL CLKs and you need only PL part, boot system with your configured PS from SD Card (You can use our prebuilt Boot.bin in case you use the same CLKs like we in our reference design) and overwrite PL over JTAG like you has done above.
