I am using a beaglebone black and a custom board based off it.
On the BBB, I am running Debian Linux 7 (Linux 3.8-13)
On the custom board, I am running Angstrom distribution.
On both boards, when I run i2cdetect -F 2, they give the same results, as below:
Functionalities implemented by /dev/i2c-2:
SMBus Quick Command no
SMBus Send Byte yes
SMBus Receive Byte yes
SMBus Write Byte yes
SMBus Read Byte yes
SMBus Write Word yes
SMBus Read Word yes
SMBus Process Call yes
SMBus Block Write yes
SMBus Block Read no
SMBus Block Process Call no
SMBus PEC yes
I2C Block Write yes
I2C Block Read yes
I REALLY need to use the PROCESS_CALL functionality of the I2C.
The question is: does the PROCESS_CALL functionality rely on the hardware?
if it is just software, any patches or drivers I could use so I could support it on my hardware?
I have searched the web with regard to this, but have not found any answers.
I am hoping this community would be able to help.
Thanks in advance,
