Seems this was a stone to my garden. I just looked at my board having WP grounded with a jumper. I can successfully write/read the 24C256 eeprom. The jumper is installed. Then, if Low there is no protection. The pin is named "WP". Positive logic. If High, then it (protection) is "true". Protected. If WP=Low=false, the write operation permitted, no protection. If you posted your results as suggested you'd have better outcome... (note: on some chips if WP is left floating, there is NO protection, you can write/read!) -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
