Hi all
I've built redboot for an XSCALE PXA270 based board from eCos CVS snapshot
around December 2006. What built with gcc 3.3.2 binutils 2.14.90 redboot
works fine. When built with gcc 3.4.4 binutils 2.15.96 it comes to
Reset caused by: hardware reset pin
Core voltage will be set to 1.150 Volts.
Clock speed will be changed to 208 MHz
clock speed set to 208 MHz ...
+
and then comes a string
$T0a0f:58ab00a0;0d:34d500a0;#0b
and it keeps repeating on every ENTER. I was told that this string comes
from some debugging mode, which is invoked due to some unrecognised
exception. Here are the used flags
-O2 -ffunction-sections -fdata-sections -fno-rtti -fno-builtin \
-fno-exceptions -fvtable-gc -finit-priority -mapcs-frame
Originally there was also a "-g" there, which I now removed, and haven't
yet checked if the problem is still there, but I think it is not the
reason.
Is the problem known to anybody / how do we solve it?
Thanks
Guennadi
