hi cybdenw,

A few questions:

Which Nios-II flavor are you using ... II/e, II/s, II/f ?

Are you booting from flash, on-chip memory, or epcs_controller?

Are you sharing pins between flash & sdram?

When bootm fails, do you see a CRC error message?

Also, if autoboot or manual bootm fails, what does 'imi 0' report?

Regards,
