Blackfin & printf()/fprintf()

[Sebastian Dressler]

Hi,

I'm developing on a Blackfin BF-532 with newlib. When i was trying to use
printf() with redirecting stdout to the UART nothing is ever printed, same
behavior with fprintf(stdout, ...).

I've written my own system calls for write, open, sbrk and so on...calling
write alone works fine, so i assume there is soemthing wrong inside of the
print-routine, but i'm not sure about that. Is there something to
initialize, that points to stdout? After debugging it seems, that printf
aborts after CHECK_INIT(data, fp).

Hope there are any suggestions. Thanks in advance.
