Preparing a USB stick for upgrading Platinum modules
- A computer running Linux.
- A USB stick that can be erased, 1GB or greater.
- Some Linux knowledge.
If the instructions on this page cannot be followed, then please request a USB upgrade stick from Güralp Systems. We will provide a ready-made stick (and cable if necessary) directly to you.
If you would rather build your own, follow the procedure below.
Identify the device name
Insert the USB stick into a USB socket on the computer. Wait for ten
seconds to allow the kernel to recognise the device, then run the command
dmesg. The output should contain lines like
sd 46:0:0:0: [sdb] 15826944 512-byte logical blocks: (8.10 GB/7.54 GiB) sd 46:0:0:0: [sdb] Write Protect is off sd 46:0:0:0: [sdb] Mode Sense: 43 00 00 00 sd 46:0:0:0: [sdb] Assuming drive cache: write through sd 46:0:0:0: [sdb] Assuming drive cache: write through sdb:
sdb1sd 46:0:0:0: [sdb] Assuming drive cache: write through sd 46:0:0:0: [sdb] Attached SCSI removable disk
The device name in this example is
sdb although the name on
your system may well be different. Note that
sdb refers to the
physical device and
sdb1 refers to a partition on that device.
sdb is used throughout the remainder of this example: substitute
the name that your system has used if it is different.
Prepare USB stick
Partition the USB stick. The partition table must be in DOS (MBR) format and not in EFI format (which is becoming the default on newer systems). It is normally sufficient to create a single partition covering the whole device.
Create an ext2 filesystem on the new partition. The following commands should be suitable for creating the filesystem:
sudo umount /dev/sdb1 sudo mke2fs -t ext2 /dev/sdb1 sudo e2label /dev/sdb1 Pt-firmware
(It is, of course, necessary to substitute sdb with the name of the
device.) Now mount the stick somewhere it can be accessed, usually on
sudo mount /dev/sdb1 /mnt
Download required scripts and firmware
Use the following
wget commands to download the scripts to be
run on the device. If you are using a mount point other than
/mnt, substitute its path in pace of
sudo wget -O /mnt/upgrade http://www.guralp.com/download/DCM/upgrade-from-disk sudo wget -O /mnt/upgrade-EABI http://www.guralp.com/download/DCM/upgrade-from-disk-EABI sudo chmod 0755 /mnt/upgrade*
Use the following
rsync command to download the required
firmware, changing the emphasised text (ARCH and mnt) as
sudo rsync -av --del rsync://rsync.guralp.com/platinum-stable/ARCH /mnt
(Note it is critical that there is no trailing slash after ARCH). This command can be run again at any time to update the firmware on the USB stick, only downloading files which have changed. To determine which architecture(s) you need:
||EAM modules, DM24SxEAM digitisers and *TDE instruments (Platinum firmware, builds ≥10000)|
||CMG-NAM-mk2 (1U rackmount)|
||EAM modules, pre EABI upgrade (Platinum firmware, builds ≤3801)|
||Legacy CMG-NAM (original 3U rackmount, with or without serial ports)|
||Legacy CMG-NAM64 (original 3U rackmount)|
||Legacy DCM modules running Platinum firmware|
If you need more than one architecture, run the rsync command above once for each required architecture, using the correct name in place of ARCH each time.
The difference between
CMG-DCM-mk4 is in the build number. If you know the units being
upgraded are already at build 10000 or greater, then only the
version is required. Otherwise, get both versions.
The upgrade scripts automatically know which firmware they need, so if unsure simply download all the architectures.
Finally, dismount the USB device with the command
sudo umount /dev/sdb1
substituting the name of the actual device used in place of sdb1.
