Never mind, It's something to do with my debugger and stepping through code. I
can get the hello world message to spit out if I break after the printf
statement.

Subject: Cyclone 10 LP BSP
I'm trying to create a BSP for a NIOS V/m running on a Cyclone 10 LP Eval Kit.
The NIOS V/m is a rv32ia/ilp32 architecture so I had to patch the RSB to add
that multilib. I have a Hello World app compiled but I get exceptions when
having the tick timer interrupt enabled. So, I disabled the tick timer
interrupt and was able to get to the Init() task. When execution the hello
world printf, I get another exception related to puts_r in newlib. The
exception is occurring when trying to load the address of _tls_stdout. I
traced this back to THREAD_LOCAL_STORAGE being enabled in newlib for the RISC
V. Does the BSP have to do anything to setup thread local storage or does this
happen automatically when triggered? The exception occurs after it returns
from __sinit which I guess is initializes the thread local storage.
