I want to write some data into the on-board eeprom & have the following questions :
1. Can I write to the eeprom by simply opening the file "/sys/bus/i2c/devices/0-0050/eeprom" ? 2. Why is this file 32768 bytes in size (I would have expected it to be 4096 bytes). The contents of the file appears to be 8 contiguous copies of the 4K eeprom contents. 3. If the answer to (1) is yes, can I open the file in read/write mode, seek to a position near the end and then write some data to it, or do I need to write the complete 4K ? 4. Do I need to erase the chip before writing to it ? I know that I will need to disable the write-protection by grounding TP4. I'm running ubuntu on a rev C Element14 BBB. As a matter of interest, I've noticed that the standard eeprom contents on an element14 manufactured BBB (Rev C) seems to have the wrong board type defined (00A5 instead of 00C0) John -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
