[Openocd-development] flash driver problem on LPC2148

[Edgar G. <edg...@zy...>]

Hi,

Using parport and SVN 607, for 2148:

$ openocd -f interface/parport.cfg -f target/lpc2148.cfg -d3 -l ./log.txt

I get the following:

As you can see, I cannot make the stuff from 0x0 to 0x40 go away.
The log file is attached. (zipped due to file size).

Restarting openOCD and power cycling the target a couple of times, makes 
things different, still not correct:
