I have observed this slow loading before.
Running GDB via the proxy on another machine on our network slows
everything down, but more recently I've been running it all on localhost.
You haven't posted what gdb-ini file you are using, so I assume it's the
default one but I'm not familiar with it.
I don't recall which 'remote' parameters caused the slow speeds. I
experimented with these commands in my gdb-ini file.
#set remote memory-write-packet-size 512
#set remote memory-write-packet-size fixed
#set remote memory-read-packet-size 512
#set remote memory-read-packet-size fixed
and came to the conclusion that using only these parameters
set remote memory-write-packet-size fixed
set remote memory-read-packet-size fixed
gave me the fastest load times, with reduced TCP overhead for fewer packets.
Our JTAG interface is the USB Olimex JTAG-TINY.

Hi,
It takes a long time when i try to load my image to MSP430FG4618 by
msp430-gdb.
Is there somebody who faced the same problem before?
My steps:
