I was looking at the common entry.S file in the latest 5307 directory and found that a small patch has been left out. Without this patch gdbserver and strace don't work correctly. (I believe the original authors are Philippe De Muyter and Stuart Hughes.) Could you apply this patch?
Applied. Thanks Greg
