help me please!!! alt_flash_open_dev return error

--- Quote Start ---

In my opinion, there are two posibble reason for the fault of open my CFI flash.

1, I use my CFI flash as boot loader flash(reset vector=CFI flash)

2, my CFI flash need add a CFI table for programing, but when i use alt_flash_open_dev ,no CFI table was added automatically.

delphicgp,

sorry i mixed something up I thought you use EPCS memory. But anyway it doesn't matter.

It looks like it is a case - if the reset vector is in the some specific flash you can't open it using open() function.

Is it a question of the Altera's boot loader implementation? Maybe you need a custom boot loader then. I'm not sure how it works.

Anyway, could you have your reset vector in EPCS and when use the CFI flash for the rest of the program?
