I was beginning a project to layout an expansion board for the beagle
board and noticed some missing information in the wiki and system
reference manual.
The following information would be helpful:
Location of the standoffs from a single point (sounded simple I thought)
Keep out region around the standoffs (I prefer to follow the standard
used by the original board)
location of the expansion connector(s) primarily the big 2.54mm
spacing one mostly in reference to pin one. The other two connector
locations would be nice as well. In case I ever want to add FFC
connector to an LCD to a board for the beagle board.
Also why did the designers choose 0x50 for the I2C address? The HDMI
connector has an I2C interface, just seems odd to use that address.
The information provided for the I2C EEPROM just includes VENDOR and
DEVICE id REVISION information but what about CONTENT and DATA fields?
Likely more questions here than answers but I thought it was worth a
try at least!
If a board has a different mux interface does this require the
producer to provide the module for the beagle board? Seems a bit
vague in the documentation what to do etc.
Have a good one.
