i2c setup on BBB

[ i2c/dev-interface ]

[ i2c | cryptocape ] hardware vs linux names | i2cdetectechoerrno.h | open() returns file descriptor

[ ?how to access /boot/uboot/uEnv.txt  ]

[ capemgr ] userspace | EEPROMs

SSHing into BBB | RSA over USB. We didn’t need a password, not yet.

The dates on all embedded systems seem to always be wrong. Corrected using sudo date -s “”

We tried the standard command for listing all i2c devices on the BBB. Interestingly, bone_capemgr.8 didn’t work for us, but .9 did!

Well, we went to the cloud9 interface, and though I just wanted to list all i2c devices through bone_capemgr*, I accidentally echo’d it, but things worked out!

Next, we need to read and write to the adapters / files associated with i2c1/2, pull some oscilloscope captures, and move onto SPI. Running Code Composer Studio on linux is also coming up this week.
