restore hangs up

restore hangs up

[Shaun Jackman]

On arm-elf-gdb 6.4 for target rdi, the restore command hangs up. The
`Restoring binary' message is the last thing I see. I see that RDI
support has been removed from CVS. So, three questions:

1. Any idea how I can fix/work-around this bug?

$ arm-elf-gdb

No, since we have no idea what the bug is.

You could certainly hack it to; I don't know if it would be generally
useful.

Use a third-party program which converts RDI to the GDB remote
protocol.  There's at least two; one formerly distributed by Cygnus
that you can probably still find (I'm afraid I don't remember the name)
and one in CodeSourcery's ARM releases, which are publicly available.
There might be others, too.

Fernando,

Do you know anything about this Cygnus GDB/RDI translation utility?

I looked into the CodeSourcery utility, rdi-stub. It requires a
dl-solib (SORDI) that consumes the RDI data. The only one I know of is
ARM's Armulator. I need one that communicates with a TCP port, but I'm
not sure one exists.

Cheers,
Shaun

EPI was bought by Mentor Graphics and has declared the Jeeni at its
end-of-life, making it impossible to get any resources from the
manufacturer. So, here's my plea. If anyone knows of a RDI-to-ADP (DLL
interface to TCP stream) dynamic library that can be used with the
rdi-stub utility, I'd be very interested in seeing it! If one exists,
it might have come either from EPI or possibly with ARM's development
tools.

If one were to grep through their proprietary toolchain, I'm
interested in hearing about any solib that defines the symbol
`QuerySORDI'.

Thanks for any information you can give! Cheers,
Shaun
