Have you tried turning on the PLL etc before pro
You mean STM32 is slow when writing data into flash?
But for ISP operation through COMM port(at a high baudrate), it can be as fast
as 20KBytes/s as I remember.

I've looked a bit more into STM32 flash programming performance and
most of the time is spent waiting for the target to complete
flash programming, i.e. it appears that it is the *target* that is
slow.
Could this be the case?

Hi Mariano
pls try to access register
MCFG 0xFFE0 0020
Status 0xFFE0 0104
and other Eth regs.
Any way my ethernet is up and running, but some time i got hung condition.
So I'm trying to debug the eth using gdb
Thanks

You might also have a permission problem in your /proc/bus/usb
(or the new location somewhere in /sys). In this
case, "strace -oa -efile ./openocd" and a careful reading of the
generated "a" file will show this.
Hi,
thanks for that hint. I did not know I could put the vid/pid in the
config file.
My openocd.cfg looks like this
# ftdi interface
interface ft2232
ft2232_device_desc "STM32-PerformanceStick A"
ft2232_layout stm32stick
ft2232_vid_pid 0x0640 0x002d
This did not help though. The output when I

I don't know this processors, but for some SoCs (e.g. Freescale
i.MX) you need to enable internal PLLs ("clock gating") before
you can access them.

You need also the device-description t
Hi all,
I'm working with LPC2368, and I like to read/write Ethernet controller
registers using GDB.
Using memory dump command at Ethernet controller registers address, gdb
shows 0x.
Do I miss something in the openocd or gdb config file ?
Thanks

Hello everyone,
I just signed up to the mailing list because I hope this is the right
place to ask questions like this.
I just got my brand new ST32-PerformanceStick and right away tried to
get it to work with openocd (It works on Windows but I would like to use
a Linux developement environment
