Pitfalls

Alignment

Every command must be word aligned. When you access the memory, word accesses must be word aligned, long word accesses must be long word aligned.

Don't use the .align directive . It doesn't works with the toolchain. Use .byte directives to do that.

Subroutines / Calls

Every subroutine that calls subroutines must start with LINK and end with UNLINK to save the return address to the stack. The blackfin CPU doesn't do that automatic.

Example:

sub:
  LINK 0x0

  ...
  CALL sub2
  ...

  UNLINK
  RTS

; STOP-Mode
: Switch your scope to the STOP-Mode if you don't need capturing during your software is working. Sometimes i got unpredictable crashs when the Device was in AUTO-Mode. Hope to find a reason for this thing soon.
