Last post by Antti Lukats - February 11, 2026, 01:09:51 PMTE0802 indeed has only Host USB-A connector. Theoretically you should be able to use it as device with custom cable. Cut two cable and solder them so that you have USB-A to USB-A cable (do not connect vbus). This may work.

Last post by Antti Lukats - February 11, 2026, 01:06:21 PMGTP trace signal length are between 18 and 24 mm on the TE0714
as of signals on TEBB0714 I just recalculated the differential impedance and got 100.16 ohms. But there are many calculators available all delivering somewhat different results.Altium layerstack is not updated with real layerstack params in this project so that makes small difference in the calculations, with altium layerstack params the differenial impedance is 109 ohms.

I guess you mean this: https://github.com/ArrowElectronics/Agilex-5/wiki/USB-Blaster-III
One question: can we upgrade the Arrow USB Programmer from CYC1000 and MAX1000 boards to USB Blaster III?
Thanks.

Last post by gvzz - February 06, 2026, 11:54:39 PMI mainly ask because attempting to compute impedance for the differential lanes according to the stackup of Simple Base TE0714:
I obtain results far from the 100 ohm differential and 50 ohm even/odd (I account that maybe is quiet difficult to obtain nearly exact results):
Computation algorithms used are:
Coupled microstrip line:
According to KiCAD docs: https://docs.kicad.org/9.0/en/pcb_calculator/pcb_calculator.html
Thanks again for any support.

Trenz Electronic FPGA Modules / TE014 GTP diff traces impedanc...
Last post by gvzz - February 06, 2026, 01:23:23 PMHi,
I am working on a small carrier card for TE0714-04-52I-7-B for which I am placing U.FL connectors on all lanes.
Since this is my first HS card, I would like to have some guideline regarding differential traces length and impedance.
As far as I know the theoretical differential impedance should be 100 ohm with 50 ohm for each trace.
I can inspect Simple base of TE0714 through Altium online viewer using AP-TEBB0714-01.zip, so the lengths on the simple base are known.
What are the GTP lanes length on TE0714-04-52I-7-B and what are the computed impedances (differential, even and odd) for the overall design, so to keep these values as reference?
Thanks,
s.

Trenz Electronic FPGA Modules / TE0720, TE0790: eFUSE programm...
Last post by andreas - February 06, 2026, 11:06:31 AMHi,
(Possibly a duplicate post?! My login session expired, and I'm wondering if the first post went through.)
We are using the TE0720 on our custom board, which was inspired by the TE0703. JTAG for standalone debugging is implemented via a mounted TE0790. We are using Vivado, Vitis, and PetaLinux (version 2023.2).
Normally, we initialize the TE0720's QSPI and eMMC after booting Linux from the microSD card.
So far, we haven't had any problems (more than 20 systems have been successfully initialized).
The problems started when we tried to program eFUSEs for Secure Boot or debug FSBL.
Both require a mounted TE0790.
I have already successfully debugged FSBL, read ILA cores, and initialized eFUSEs with our custom board and a mounted TE0790.
However, there are cases where the TE0790 and/or the TE0790 module are damaged!
The TE0720 module operates with a 3.3V power supply (like the TE0703). The TE0720's FPGA banks are supplied with 1.8V (VCCIOA, VCCIOB, VCCIOC, and VCCIOD are all set to 1.8V). The TE0720's CPLD revision is 07 (default).
The TE0790 is powered via VCCJTAG. The TE0790's switch has the positions [On, Off, On, Off].
Do you have any further information? Any hints how to prevent further damages?

Trenz Electronic FPGA Modules / TE0802-02-1BEV2: Native PS USB...
Last post by mariem - January 30, 2026, 11:40:27 AMHello,
I am working with the TE0802-02-1BEV2 module and I would like to use the native Zynq UltraScale+ PS USB controller (USB0 or USB1) in USB Device mode (CDC ACM).
From the TRM I see:
One USB 3.0 Type-A connector listed as USB Host
One Micro-USB connector for JTAG/UART via FTDI
My questions are:
Are the PS USB controllers (USB0/USB1) routed to any physical connector on the TE0802-02-1BEV2 that supports USB Device or OTG mode?
Is it possible to configure the USB 3.0 Type-A port in USB Device mode by software only, or is it hardware limited to Host mode?
If native USB Device is not available on this board, is there any recommended modification or expansion board to expose USB0/USB1 in Device mode?
Thank you in advance for your support.
Best regards,

Last post by d.signer - January 24, 2026, 12:33:17 PMBTW the 2. link above to the schematics was obtained from the 1. link above in the Download section, however this is not for the CR00240-02-A. Where can I find the "02" version schematics?
The modifications are mentioned in the PCN in the Download section:
https://www.trenz-electronic.de/trenzdownloads/Trenz_Electronic/CRUVI/CR00240/PCN/PCN-20251204%20CR00240-01%20to%20CR00240-02%20Hardware%20Revision%20Change.pdf
But there is no information on how the MIPI signals are connected to the CRUVI connector.

Last post by d.signer - January 24, 2026, 09:32:48 AMI recently got a CR00240-02 which has both a HDMI and MIPI connector and is titled "CRUVI-HS HDMI and 15-pin CSI-2 Camera Adapter":

But the schematics:
https://www.trenz-electronic.de/trenzdownloads/Trenz_Electronic/CRUVI/CR00240/REV01/Documents/SCH-CR00240-01-A.PDF
has no sign of a MIPI connector. Is this an old out of date schematics? If yes, where can I find the current schematics?
