----------------------------------------------- hi andy. 2.01 works fine. A small observation: IF clock bit was previously set and security bit unset and you select in step 4 of flash magic verify after programming, fill unused flash, set security bit 1, and 6 clocks/cycle then flash magic does not set security bit. You have to select in step 4 of flash magic verify after programming, fill unused flash, set security bit 1, and "uncheck" 6 clocks/cycle. Then flash magic sets security bit. Can flash magic "first read" and then write if a bit is not set? Regards Lambros Sirivlis ---------------------------------------------- |
