Hello, I think I am doing something fundamentally stupid. I wonder if somebody competent could have a quick look at the following config file + telnet transcript and tell me why the flash is always protected and why I cannot erase it (or write anything there).

> geckosenator: > I have the same problem OK, the line for LPC2000 flash should look like this: flash bank lpc2000 0x0 0x40000 0 0 0 lpc2000\_v2 14746 calc\_checksum i.e., the zero preceding the clock rate should be removed. According to the new format, it now occurs before the variant (lpc2000\_v2). I copied the file from some place with that error. Now it seems to work. Kris
