I'm trying to follow the Altera DE2-115 with Linux sample from this link (http://www.alterawiki.com/wiki/linux_with_mmu_on_veek/t-pad#unfortunately.2c_if_you_don.27t_have_veek.2ft-pad_kit.2c_but_you_have_de2-115...).
The first part works but then I get
$ nios2-flash-programmer --epcs --base=0x0a001800 tPad_Selector.flash --debug
Reading override file "/opt/intelFPGA_lite/16.1/nios2eds/bin/nios2-flash-override.txt"

Altera_ForumWhat hardware are you using? Is it a DE2-115 or are you simply using that link for reference?
If it's you own hardware - what EPCS device are you using? And, if necessary, does it have an entry in the nios-flash-override file? If you're on a DE2-115 board then I suspect you've specified your base and/or boot addresses wrong when you've configured your Nios. Refer to one of the examples that come with the kit for reference.

Hi,
There are few possibilities based on the error message, usually this is due to the flash programmer not able to find the EPCS flash. Please check the base address, and make sure the HW connections are OK.
