Strictly speaking, this isn't true. If you drop the Altera provided syslib/bsp entirely, you can avoid all the default C runtime and initialization stuff.

If you include the syslib/bsp as it appears the OP has done, then you do need to define either _alt_main or _main as you have suggested.

Hi，Kevin.

It's kind of you .

I have modifed the assembly code using

.global _alt_main

_alt_main:

instead of

.global _start

_start:

But it does not work, yet occur errors as mentioned by me.
