@Ian-Marchant hi ian, to save me reinventing the wheel, can you give me details of what you have ordered and where from? £11 sounds doable so will follow suit..

worked by connecting to 2 satellites while sky was totally clear, as soon as any cloud cover appeared stopped, i'm assuming the antenna as supplied is next to useless. bit of a shame really.

if anyone is thinking of buying this device i'd suggest thinking twice..

woooo hoooo!!

locked to a single satellite!!!

it does work, just badly..

grab a copy of the ublox u-center util, you will see the output from the device. you'll need a windows box to run the util.

i run a time server that uses gps and i have a very small external antenna, this device locks within seconds, so this is now the gps device should work, adding an external antenna to such a small board would be far from easy and would negate its small size.

i'd like to hear from onion as to how they suggest we get the gps working properly.

i have clear skies today so will give it another go..

hi,

other than running my own fleet of gps satellites with my gps receiver 2 inches away from them...

what is the secret to getting the receiver to actually lock to anything?

got it on a long usb extension and having been waving it around outside all morning, downloaded and installed the ublox u-center to see what is actually going on and i able to report nothing is going on.. not a single squeak from any satellite.. the receiver is live and sending info back to u-center, seems to scan through satellites ok, can't lock to anything..

would love to hear from anyone who has got things working..

@fossette only works as a mountable storage device once it was formatted ext4, the flash storage format was not mountable..

sorted!!

sorry to waste peoples time..

rup

discovered e2fsprogs so now having another go using ext4..

rup

or if mkfs.f2fs is not suitable, can i get and use mkfs.ext4 or mkfs.xfs?

rup

hiya,

just got my system and started to play with it, have added a 64gb microsd to the processor board and can see it using fdisk -l

have made a partition and formatted it using mkfs.f2fs

Disk /dev/mmcblk0: 59.1 GiB, 63416827904 bytes, 123860992 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x00000000

Device Boot Start End Sectors Size Id Type
/dev/mmcblk0p1 2048 123860991 123858944 59.1G 83 Linux

now i'd like to mount it, so have made a nice directory /mnt/big/

drwxrwxrwx 2 root root 0 Jan 23 17:40 big

but if i run:

root@Omega-7923:/dev# mount /dev/mmcblk0p1 /mnt/big/
mount: mounting /dev/mmcblk0p1 on /mnt/big/ failed: Invalid argument

as you can see it fails..

what should i be doing?

cheers!!
