Hi all, Just having a crack at getting the PocketBeagle going. If I plug it in to USB with no SD card attached, I see the blue power LED come on, and the following kernel messages:

I grabbed a 16GB microSD card, only to find it was a dud. The ones I have spare are 2GB ones. Okay, fine, I loop-mounted bone-debian-9.2-iot-armhf-2017-10-10-4gb.img and had a look at /dev/loop0p1. Sure enough, there's a little over 2GB spare, so in theory, I should be able to shrink that partition down and make it fit. On the image, under /opt/backup/uboot, I found what looked to be the images needed for the U-Boot bootloader… and over at https://eewiki.net/display/linuxonarm/PocketBeagle#PocketBeagle-Bootloader:U-Boot … some notes on how the SD card images are constructed. Despite carefully preparing the SD card and rsync-ing the root filesystem across, it seems I get no life out of the PocketBeagle. I grabbed my 3v3 USB FTDI serial cable out and hooked the RX and 0V wires to the U0 TX and GND pins on the PocketBeagle and power cycled it. No life. Has anyone managed to bootstrap one of these with an image of this size? Unfortunately most shops are winding down for Christmas, and so buying a new card really isn't an option just now. I'd like to get an image on there to prove the board fundamentally "works" before I get to setting things up proper. -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
