Probably the kernel crashes as soon as starts...it is difficult to say... :confused:

You shoud try to check if BOOT_LINK_OFFSET is ok...it should be at 2/3 of RAM to avoid that uncopressed kernel overlaps the uncompressing one...even if it shoud crash before and you should see only Uncompressing Kernel Image in my opinion....

For the debugging...you might for example add printk to init_BSP in config.c in arch/nios2/boards/'your board' ....otherwise put printk before...in the caller of init_BSP...search...

For printk examples, grep the kernel or on internet...you should see your printk on the consolle...

Hope help :confused:
