Re: [beagleboard] Unable to access/talk to BBB after netinstalling Ubuntu
I did have a serial debug cable connected :). Turned out the right angle serial connector between the cable and the J1 went bad. But the BBB seems to be booting into the default debian in the eMMC rather than the Ubuntu programmed into the microSD card using netinstall. Here's the output: U-Boot 2015.01-1-gb2412df (Jan 29 2015 - 15:01:06), Build: jenkins-github_B5 Watchdog enabled I2C: ready DRAM: 512 MiB MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 Using default environment Net:not set. Validating first E-fuse MAC cpsw Is the SD card being recognized correctly by uboot?

[beagleboard] Beagle bone serial console
This may be a naive question but how might I be able to obtain access to BBB J1 connector from a Cape board stacked on it? In other words, how and where should I attach the 3.3V TTL serial console cable that I used with BBB J1 connector when a cape is stacked? According to: http://www.toptechboy.com/wp-content/uploads/2015/06/beaglebone-black-pinout.jpg, serial console UART0 from J1 connector is NOT exposed over the 40 pins. Is that correct? If so, what is the alternative to connect to serial console prompt?
