After moving the tristate controller out of the qsys subsystem the driver is added and the function alt_flash_open_dev returns a valid pointer.

It seems that quartus 13.0sp1 has a problem with submodules and tristate controllers. Is this a known issue?

Anybody can tell if this problem is fixed in a later version of the toolchain?

Hi Thomas,

I am currently having the same problem, and I am using version 13.1.4. However, when you say you moved the tristate controller out of the qsys subsystem, where did you move it to? Was it deleted from your entire project? When you used alt_flash_open_dev to return this valid pointer, were you able to read and write to the flash correctly? Sorry for all of the questions, and thank you in advance.
