I've been trying to use the CFI Flash on the "Arria II FPGA Development kit, 6G edition" but I just can't get it to work.
The flash is a Numonyx 512P30 (P/N PC28F512P30EF). The error I get during uCLinux boot is:
of-flash 0.flash: do_map_probe() failed
The device is successfully added to QSys, it works fine outside uCLinux (with Altera's HAL + SBT)
I'm quite sure my kernel configuration is OK because it is able to probe the CFI flash on DE2-115 board.
The DTS file seems to be fine as well.
If anyone could please answer any of the following questions:
* Have anyone already got this particular CFI Flash chip to work on uCLinux?
* If this chip is not supported, how should I add support to it? Is linux-2.6.x/include/config/mtd/jedecprobe.h the right file to edit? Could be adding an entry to the table at the top of the file enough?
* An alternative would be porting the Altera's HAL driver to uCLinux. If I could use alt_write_flash() on uCLinux that would be enough. Any clue on that?
Thank you so much!
