Hello,
I have patch for openocd so it can write and erase the flash memory on an ADuC
702x microcontroller.
The patch worked with an older version of openocd. Now I've applied the patch
to the latest SVN code and suddenly the program segfaults when try to write or
erase the device. Can anyone help me make it work again?
The original code was written by Kevin McGuire I think, I can't find the
original web page any more. all the credits for the patch should go to Mr.
McGuire
Thanks in advance,
Marcel Wijlaars
