Hi YTLim,
There are few things that would like to check with you:
- May I know what is the failure rate? Does this issue happens on all the boards?
- What is the the type of SPI flash used in the board?
- Have you try to unload the content program into the SPI flash and compare it with the original file to make sure the content stored in SPI flash is not corrupted?
- After configuration, you mentioned that the device hang and is not functioning, can you probe the "CONF_DONE" pin? Is it in HIGH state?
Thank You.
Hi YuanLi
To answer some of you questions
Failure rate is 100%. Failed on 3 systems that we have tried.
SPI flash chip is the Altera EPCQ256
No, we did not unload the program from SPI chip back to compare. Need get help from you guys on how to do that.
CONF_DONE signal was "low" when it fail with the bad version of the POF file. Other good version of the POF has the CONF_DONE signal "high".
Rgds,
