Dear Sir, Because Arty's J10 was broken.So my client bounght PMOD USBUART/Power Adapter /JTAG HS2. 1.About PMOD USBUART's Jumper JP1. (Does it use default settiing? Set JP1 as SYS3V3 (remove power adapter )and it can provide the power to Arty but it can not download) When host computer connect with PMOD USBUART .The device manager show recognize this device (COM 3,It is FTDI driver). 2. Power on power adapter and download below project bit file to Arty via JTAG HS2. Arty's LED is work fine. But PuTTY does not has any output. Do you have any suggestion?

@attila Thanks for your help.

Dear Sir, How to know the Impedance range and its ccuracy? Wavefroms show 1 GΩ~1nΩ. Best Regards, Paul

@JRys Thanks for your anwser.

Dear Sir, Below picture is our job. (I would like to know the maximum current that AD2 can handle. Does it damage the AD2?) Best Regards, Paul

Hi @zygot We know the root cause, Thanks for your answer. Best Regards, Paul

Dear Sir, I have a question about io voltage test. Our Configuration : NEXYS Video board + Xilinx FMC XM105 debug board. We set up IO to 1.2V , IO add a pull-up to 3.3V IO is set to output and logic 1 => voltage at this point: 1.2V =>OK IO is set to output and logic 0 => voltage at this point: 0V => OK IO is set to High-Z => The voltage at this point is about 2V IO is set to input => the voltage at this point is about 2V => Are them correct? Best Regards, Paul

Dear Sir, We have two zedboard (One version is 2012 and another is 2019) When I run the ZedBoard FMC Pcam Adapter One to Four Camera Demo example. Old version board is no problem and new version board can not work.(Uart does not print anything and sometimes can not access ddr and ip address) It is currently suspected whether it is caused by the difference in DDR. (2012 zedboard's DDR) (2019 zedboard's DDR) We have tested the OOB demo from website and bundled SD card. Website's image seem fail. Bundled SD card is ok. (see attach log file) What's different between two version of zedboard? How to solve this issue? Best Regards, Paul log.txt
