Dear Sir, I have aquestion about Genesys ZU-5EV. Its ethernet is support 1G w/ IEEE 1588. If I use this out of box demo image. Can I test PTP with open source linuxptp application ? MacbDriver-PTP Linux PTP Project Best Regards, Paul

Hi @Ionut It worked fine at the beginning and then at some point it started to behave like this. We bought this board in 2022.11. Best Regards, Paul

Hi @Ionut, Our board boot on SD card. LD13 LED is off. VADJ voltage on the board is 0v. Best Regards, Paul

Hi @Ionut, 1. LD13 LED did not turnn on. 2 The 12V supply that came in the box with the board. 3.Turn the board on and off several times and it still can not power on. Best Regards, Paul

Dear sir, Our another zedboard encountered problem. When we turned on power , the LDO LEDs were all on as the attached the picture. We measured the Vadj pin and found Vadj short with ground. May you verify the possible rootcause and advise . Thanks. best regards, paul

Dear sir, Any suggestions for this situation? best regards paul

Dear Sir, Our zedboard's power led was not turned on after plugged the power line. It does not work if we try to program by Jtag or boot from sd card eithter. May you advise any further step to fix it? Best Regards, Paul

Hi @Fausto, Thanks for your support. I have reinstall everything (OS and python and GitHub).Now it is work fine. Best regards, Paul

Dear Sir, I have an MCC 128 device mounted on a raspberry pi 4B.(OS is Raspbian GNU/Linux 10) RPI configuration :SPI and I2C are enabled. It can not open device It can not update firmware also. I also ref below link and change another charger . https://forum.digilent.com/topic/25678-mcc-128-unexpected-device-id/ It still can not solve this problem. Do you have other suggesion ? Best Regards, Paul

Dear Sir, I have two questions below: 1. Eclypse z7 and ZMOD ADC 1410 When I use TCP_perf tcp_write library in Vitis,the error message 'xps_ethernetlite drivers not present' will occur. Could you tell me how to solve it? Plain text test data (ex:0123456789...) is no problem. 2. I would like to implement ZMOD ADC 1410 with Genesys ZU 5EV. In Vivado, the ZMOD library seems can not update IP well. Any suggestion? Please see picture below: Best Regards, Paul

@JColvin Thanks for your help.

Dear Sir, Is it possilbe to set up MIPI CSI to Transimter? Best Regards, Paul

Dear Sir, I have implement my design in CMODA7. (Also mount a 100Mhz oscillator with CMODA7) My three idelay2 modules are FIXED mode. Taps are 0 ,0 ,0 50Mhz is my input signal. simulation: DATAout1:3.915ns , DATAout2: 4.736(3.915+0.821)ns , DATAout3: 5.762(4.736+1.026)ns measurement: DATAout1:4.044ns ,DATAout2:5.088(4.044+1.044)ns ,DATAout3: 6.445(4.044+1.044+1.357)ns I would like to know why three Taps of idelay2 are all zero but their delay are different. Best Regards, Paull

@elodg Thanks for your anwser.
