But I get only download speeds of 1kB/sec. Why is this so slow? How can
I speed up the download?
My start-script from Eclipse (Zylin Embedded CDT) looks like this:
init-commands:
target remote localhost:3333
monitor reset_halt
monitor gdb_breakpoint_override hard
monitor arm7_9 dcc_downloads enable
monitor reset init
monitor sleep 500
monitor poll
monitor flash probe 0
monitor flash erase_sector 0 0 15
load
I can't find any mistake in configuration.
you sure this is correct?
if openocd is correctly sending the memory map then the
gdb_breakpoint_override and erase/probe are not required.
Also is the first monitor reset_halt a typo?
a debug log of openocd would help to verify any other issues.
Cheers
Spen
thanks for fast response.
Well, I'm not realy sure ;-)
The normale output of openocd looks like this (If this is not enough, I
can also post a logging with debug messages enabled)

break ResetHandler
What I'm confused about is that OpenOCD says in log there are nor DCC
Download enabled but in the GDB Console it shows
monitor arm7_9 dcc_downloads enable
dcc downloads are enabled
I'm also not sure whether my reset-init event handler is executed. I
only see Info : clock speed 2000 kHz and not 6000kHz
best regards
Andy
