Hi all,
We are porting bsp for IXP 425 board using
AXD debugger and
multi-ice(JTAG) which needs debug mode (correct ?).The manual "Intel(r)
IXP42X Product Line of Network Processors and IXC1100 Control Plane
Processor" , say's that in debug mode does not have a dedicated stack
pointer and following instructions should not be executed in Debug Mode,
they may result in unpredictable behavior LDM ,STM,LDR w/ Rd=PC , LDR w/
RRX addressing mode, SWP, LDC, STC
But as part of boot up code these
instructions ( in reset_vector after PLATFORM_SETUP) Are used like
stmfd, ldmfd.
Any pointers to resolve this or any sugessitons
Thanks & regards,
Sumanth.
