Can someone tell me the state of serdbg and rtems-stub-glue?
I’m trying to write an RTEMS thread aware gdb stub for ARM based on serdbg and
rtems-stub-glue.c, following the implementations given for other CPU
architectures.
First, it seems strange that there isn’t an ARM version already. I’ve been
assuming that that’s probably because no one has gotten around to it yet, but
I’m wondering… What do ARM developers typically do?
Next, I found that int2fhstr() doesn’t preserve the endianess of the target
architecture when encoding data for GDB, whereas mem2hstr() does, as the GDB
manual says they should. Should I fix this, or am I missing something?
Finally, serdbgio doesn’t provide a close() function that could be used to
restore the serial connection when the debugger detaches. This would be useful
in the case when the serial connection is shared with the console. Should I
provide this, or am I barking up the obsolete tree?
Thanks,
Ric
