Hi, Background: I have a BBB that I am setting up to run with machinekit to drive a mill. I have been testing with an early machine kit image, and then I updated to the most recent image. Upon updating I started to have problems where the cape manager stopped working and the pru was not recognized.
Ok, to narrow down the cause I reloaded the original (possibly updated?) emmc image and reflashed it to the BBB. (BBB-eMMC-flasher-2013.09.04.img ) Now the board will not boot to Angstrom. The serial console log of the boot attempt is attached. The key part seems to be: U-Boot SPL 2013.04-dirty (Jul 10 2013 - 14:02:53) timed out in wait_for_pin: I2C_STAT=0 Could not probe the EEPROM; something fundamentally wrong on the I2C bus. Could not get board ID. Unknown board, assuming Beaglebone LT/Black.musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, HB-ISO Rx, HB-ISO Tx, SoftConn) .... Is there a way to determine if this is a hardware error with the I2C bus, or an EEPROM that needs to be reloaded?
