[SOLVED] RPi won't boot from SD image

AstroBox Troubleshooting
#1

I have downloaded the RPi image file from your site twice, and flashed my SD card twice (after formatting the card the second time). I have been flashing RPi images for a couple of years now, so feel pretty confident that this part of the process is correct. When I put the SD card in my RPi B+ and plug the power in, the power light is red as is the activity lite, with no blinking. I have tried with nothing but the power connected to the RPi, with an HDMI monitor/keyboard/mouse connected, with and without the wireless dongle. It appears to simply stall with nothing on the monitor and no appearance if the RPi on my network. Any help/suggestions most appreciated.

Update: I should have mentioned that this happens on two RPis, both of which are running various versions of Raspbian just fine.

This is a very abnormal problem. If you are 100% sure that your RPi’s are fully functional, I would suggest double checking the MD5 hash listed in the downloads section with the image you have already downloaded to confirm integrity.

The other potential issue could be a bad contact point on the SD Card. Try to boot it up while applying some light pressure on the card. If this works, you can add some tape to hold it down.

So, not to step on anyone toes here, but how exactly DO you flash the RPi image file? :innocent:

Pretty simple :wink:

Thanks for the suggestion…will try when I get home later today.

I used the dd command in OS X. This is described in many places including IIRC, here in the downloads section.

Hehe, I meant this guy, as it didn’t work :wink:

My steps on Mac:
Find the SD card:
diskutil list

Mine is typically:
/dev/disk2

Unmount it:
diskutil unmountDisk /dev/disk2

CD to the image:
cd Downloads

“Burn” image to SD:
sudo dd bs=1m if=AstroBox-rpi-0_8_3-20151002.img of=/dev/rdisk2

PS! Note the “r” in front of disk2, this will make it go MUCH faster. A typical SD card should take 2-5 minutes max to burn image.

That’s exactly what I did. The SD card appears to be OK, but does not boot

#9

Have you tried re-downloading the image?

#10

I have downloaded it twice with no luck. I tried the manipulation of the card you suggested…no joy. Next, I’ll try a new SD card…who knows?

#11

Yeah, let us know if a new microSD card works. Your problem is definitely not a common occurrence.

#12

I’m having the same problem. It looks like it is booting up and then the red light go solid, no activity from the green light. The Wi-Pi module never lights up either. Octoprint bootsfine.

I have tried burning the image twice. Opened the card up in Windows explorer and it looks like a lInux os.

I’m open to suggestions…

Raspberry Pi2
ScanDisk 8gb MicroSD

MD5 Checksums match

I plugged in a keyboard and monitor and it is booting up, just not activating Wi-Pi and the adhoc network.

#14

just realized i have the wrong wi-fi dongle.

#15

Ah! For reference, this is the WiFi dongle that we recommend :wink:

Fired right up with Edimax N150!
