[ECOS] Problem with eCos debugging
Thu Nov 13 09:52:00 GMT 2003
My eCos platform is OpenRisc. We have ported the OpenRisc Reference
Platform (ORP) to a different FPGA development board, so I created a
Platform HAL based on Scott Furman's ORP HAL. I've got eCos up,
multitasking is running. I have a serial port and can exchange commands
with RedBoot through a terminal app (although these commands mostly
don't work). I can place a breakpoint() call in my code, and I can then
attach gdb and find that it stopped at breakpoint().
However, the gdb backtrace is empty. Sometimes there is only frame#0,
sometimes there is a frame#1 called "??". Stepping does not work.
What could be broken, and where should I look? Should it be possible to
attach gdb without the breakpoint()?
