I've noticed that. Easy to do and works fine.
Thanks again for your help.

Sorry, I forgot to mention that :-(
There are two ENORMOUS test points, TP1 and TP2. Put a piece of wire
between them and the EEPROM is unlocked for writing.

Shame on me... I missed that.
I will cut the power to that pin and try again tomorrow.
Thanks for your help.

Hello,
I had the same need and try to change my RS485 cape into a 232 one on my BB
White.
I have the folowing issue :
the command cp eeprom.new /sys/bus/i2c/devices/3-0054/eeprom failed due to
connexion timeout.
When trying some commands with i2ctools, the ressource device seems to be
busy.

Sure, here it goes:
First of all, the CANBUS, ProfiBUS, RS232 and RS485 capes from
Beagleboardtoys all share the same PCB. It's just different components
mounted, and different jumpers configured.
So what I did to the hardware was to unmount the 5 jumpers connecting the
CANBUS chips to the UART

Ah, so you were able to edit the eeprom through a sys file then? A
Thank you Gary, brilliant!
That made it simple to alter the partnumber and get the correct dts loaded:

You use one of the Linux I2C EEPROM drivers to access the EEPROM like a
file. I don't have any capes, but it is quite possible

You must have some magic Hexedit that writes I2C . Very nice (-: how does that
work?

Please try to understand the question before responding :-)
Hexedit is a fine tool for editing binary files on your hard disk, but it
has no knowledge what so ever of I2C bus communication or EEPROMs

hexedit works for me just fine

Several reasons, but please, this is not the topic of this post. I would

If you need RS232 , what my first choise is USB convert . since you need
some chip convert from UART to RS232 , why not use USB ?
Maybe you can consider it

I needed a couple of RS232 ports for my BBB. However there seems to be a
shortage of RS232 capes in the world, Farnell is quoting over a month
delivery time.
But they had CAN-BUS capes in stock, and that's the same PCB. So I got a
couple of CAN-BUS cards and made the following modification:
