[beagleboard] Re: Advice needed on building a device tree overlay

I did the following: - I fetched https://github.com/beagleboard/bb.org-overlays - copied the file BB-I2C2-RTC-DS1338.dts to BB-I2C2-RTC-DS1307.dts - edited BB-I2C2-RTC-DS1307.dts to refer to my DS1307 chip instead of DS1338 - make src/arm/BB-I2C2-RTC-DS1307.dtbo - sudo cp

[beagleboard] Advice needed on building a device tree overlay

How do I install a single overlay? I'm writing and building a device tree overlay for a RTC chip (a DS1307) on a cape board that we designed. I want to communicate with the chip over the I2C bus no. 2 on a beaglebone black. I know how to build the overlay using dtc, and I know I must copy the

[beagleboard] Need Ubuntu version that supports capemgr

I want to install a version of Ubuntu on a Beaglebone Black rev C that supports the capemgr. I will be using an XBee cape and want to enable UART2 by adding "cape_enable=capemgr.enable_partno=BB-UART2" to /boot/uEnv.txt. I will also need to enable an i2c port to interface to a real time clock

Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit

Robert, I installed Ubuntu (not Debian), by following your instructions for copying the raw microSD image to the microSD card: http://elinux.org/BeagleBoardUbuntu#BeagleBone.2FBeagleBone_Black Then I inserted the card in the BBB, held down the boot button while powering up, and it booted from

Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit

Robert, Holding down the boot button doesn't work, I get the Bad Linux ARM zImage magic error mentioned above. When you say it has a later version of u-boot, do you mean the eMMC has a later version of uboot than my microSD card? How would I fix my uEnv.txt? Here is my uEnv.txt script from

Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit

Robert, I haven't actually written the Ubuntu image to eMMC yet (I have on the first five BBB's but not on the sixth, I can't get past step 1 on the sixth). This is my goal. 1. Get Ubuntu installed on a microSD card. 2. Configure the BBB to boot from the microSD WITHOUT pressing the boot

Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit

. William, thanks for your help. I will have to buy a FTDI cable before I can give this a try. But I have a question. My BBB doesn't boot from a microSD, all LEDs come on immediately and stay on. How can I connect to it in this state? If I have a serial console connection to the BBB

Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit

Robert, could I connect a keyboard and monitor and see the boot messages on the monitor, the same boot messages that would appear on the serial console? I'm asking because I could connect a monitor today, but I'd have to order a FTDI cable, which would take a few days to arrive. Thanks, Tim

a microSD card with Ubuntu 12.04.2. In fact, I took the microSD card from one of these BBBs and inserted it in my new BBB, and it doesn't boot. This seems to indicate that my new BBB is defective. Do you guys agree? Tim M -- For more options, visit http://beagleboard.org/discuss --- You

Robert, Unfortunately I don't have a ftdi usb-serial cable. But if I get one, can you refer me to instructions on how to use it? Thanks, Tim -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard

Re: [beagleboard] Re: Beaglebone Black won't boot from Micro SD, all LEDs remain lit

I meant that I've never used the debug port and an FTDI cable on the BBB. I assume I would connect to the BBB using a serial terminal program (in my case I would be connecting from Windows). When Robert said I could prove it easily by plugging in a ftdi usb-serial cable into the debug port, I
