Re: [beagleboard] X15 Boot via USB

Hello Robert, Is the R444 a reference to the resistor number or is this actually a surface mount with a resistance of 444 ohms? I'm not sure I have the dexterity or vision to solder that small of a component back on and I'm not that old. It sounds like my best bet would be to wait for

Re: [beagleboard] X15 Boot via USB

Hello Robert, Thank you for the reply. Let me first make sure that I have followed the correct procedure for booting from eSATA. Please review and let me know if I did anything wrong or I missed a step... 1. R444 resistor removed 2. Jumper placed on J3 between 1-2 and soldered 3. X15 debian

Re: [beagleboard] X15 Boot via USB

Sounds like I may missing something. I'm assuming u-boot would be on the debian image written to the SATA drive via dd? Do I need to install this separetly? The Beagle Bone Black is pretty straight foreward with good documentation. The X15 is not. Are there any more detailed instructions

[beagleboard] X15 attempt at SATA boot failed

Hello, I just tried to set up the X15 for a direct boot from eSATA. I purchaed an external SATA drive and eSATA cable and wrote the latest X-15 debian image to it via dd. I removed the R444 and placed a jumper from J3 1-2 and attempted a boot - FAILED. The power LED illuminates. The LED

Re: [beagleboard] X15 Boot via USB

Hello Gerald, I removed the resistor and placed a jumper between J3 1-2 attached a sata drive with a new debian image written via dd and am unable to boot. I'm getting a blank screen and the power LED comes on and the LED between the power connector and the RAM illuminates for just a few

Hello Gerald, Thank you for the quick reply. Can you review the image attached and confirm this is what I should do? Please refer to highlights in bright

Re: [beagleboard] X15 Boot via USB

Hello Jason, Thanks for the reply. Can you tell me what to put into the /boot/uEnv.txt file to do this? Do I install debian/OS image to the USB hard drive and just link to uEnv.txt to that? I would like to just install another image/OS on the USB drive and have the EMMC boot refer to that?

[beagleboard] Boot from USB external drive or eSATA

Hello, I just purchased an X15 and the EMMC memory is rapidly filling up. I would like to do one of two things... 1. Boot directly from an external hard drive via USB and bypass EMMC 2. Boot from eSATA Questions... 1. Is it possible to boot directly from USB and if so how? 2. Are there more

[beagleboard] X15 Boot via USB

Hello, I just purchased an X15 and the EMMC memory is rapidly filling up. 1. Is there a way to boot from an external USB hard drive? or 2. Can someone provide more detail directions on switching boot sequence to boot directly from eSATA? The reference manual is very vague on this. You need to

[beagleboard] Re: GPIO AINx output fluctuations

Thanks! That did the trick. This would be a pulldown resistor correct? I had to use a 330k to not loose the 0.6v input threshold for activation. Here is the new data... Smaller values are baseline and larger consecutive numbers are with alarm activation. If I want to get it cleaner I suppose I

[beagleboard] GPIO AINx output fluctuations

Hello, I am trying use the Beaglebone Black to monitor a smoke detector activation. I have two wires coming from the smoke detector, ground and positive lead. The voltage on the wires will go to 0.6v when the detector is activated. I have the ground connected to the P9 header GNDA_ADC and the
