Re: CONF_DONE pin failed to go high problem
Hello I am using Quartus Prime Version 21.1.0 Build 821 10/21/2021 SJ Standard Edition. I don't have an encryption. Tried to burn also with latest Quartus standalone programmer only with different verified jic and sof (only for FPGA download) files but without success. Is it possible that FPGA is damaged (as sof file not working)? Or it still can be related to possible corrupted contents of flash that somehow overcomes even FPGA only sof file download attempts? Thank you. AlexRe: CONF_DONE pin failed to go high problem
Hello The NCE pin is do connected to GND as shown in the attached PDF of first message. My questions as I posted: 1. Can it be that all this caused by jic files? 2. You think that maybe the issues I have are because of defected initial burning equipment like USB blaster or momentary problems in power supply that damaged 2 FPGA's? 3. You think that I can ignore these phenomenon based on fact that I have few hundreds of working boards (even they burned only once from JTAG, while all updates if were needed were done from serial port with .flash files) or I must dig in my design in searching design issues? Thank you AlexRe: CONF_DONE pin failed to go high problem
Hello Fakhrul 1. I tested with JTAG cable only 2 boards and with both of them have the same issue. Third board was burned in a different way - through remote update option (RS232 and not from JTAG). 2. I tried to burn 'damaged' boards with different validated jic files, also with simplified jic with empty project (just pins were defined) and even tried to download only sof file. 3. The screenshot of the message attached. Thank you. Alex
