Starting up a new board with a PXA270, the console output from printf calls in board.c contains garbage, whereas puts works fine. It appears the vsprintf call in printf works correctly, but printf's local char buffer has a few alternate correct characters at its very beginning followed by junk.
Everything else seems to work correctly: this SDRAM area can be written to with a debugger. But test functions (similar to printf) that copy a string parameter to a local buffer and then call puts also produce garbage.
Buffers initialized (i.e., char t [12] = "Testing...";) in these functions will print (with puts) ONLY if their size is <= 32. Their contents become garbage when other data are copied to them, regardless of size.
I haven't yet tried to start a ramdisk or image; without correct output from printf or the debug () macro it would be futile.
Thanks for any ideas.
