New ContributorHi Frank,
thank you. Unfortunately looks like this. I also did not find any explicit mention. Nevertheless I would appreciate from Altera when there would be a warning message in the console log (at least) that I am trying to do something not supported. Since having SDM I found no way of testing the memory connection over JTAG when something is wrong. In the BSDL file there are no IO buffers defined for the SDM_IOxx either.
What was by the way a strange thing in the AN995 that it was mentioning that I have the ASx4 debugging available when the FPGA programmed with an active serial x4 enabled image. So the question is that setting also part of the SRAM image I am programming? does the FPGA know that the .sof image I program supposed to be read normally from NOR over ASx4?
Or it is more related to the MSEL inputs only and nothing else.
Thanks,
Peter
Regular ContributorHi,
You will be able to access the QSPI Flash when you are using MSEL set to JTAG mode. https://docs.altera.com/r/docs/847422/25.3.1/device-configuration-user-guide-agilextm-3-fpgas-and-socs/debugging-guidelines-for-the-as-configuration-scheme
May I know which board are you using and if you are using custom board, can you share with me your board schematic so that I can understand what is actually causing the issue?
If you are able to provide some screenshot of the SFDP then it will be also provide some basic information.
