L4E1 Cellular Radio Firmware Update

These instructions help you to update the cellular radio firmware for all Conduit platforms with L4E1 radios (MTCDT-L4E1, MTCDTIP-L4E1, and MTCAP-L4E1).

Prerequisites:

  • Enabled SSH via ethernet LAN in order to copy the firmware to the unit.
  • The device’s /tmp should have > 110MB space available.
  • Disable cellular on the UI if it’s in WWAN mode (mPower only).

1. Go to the Downloads page and download the zip file for the L4E1 Cellular Radio Firmware Update Files. Unzip these files.

2. Copy the LE910C4-EU_25.20.676_CUST_069_perf_STR.bin ,l4e1_flash abd uxfp files to /tmp using a program like winscp or Filezilla.5.1.8

3. Verify that you are on a lower version of radio module firmware

sudo -s
radio-cmd at+gmr

If the system returns 25.20.673, then proceed to step 3. If it reutrns “M0F.670006″ then the firmware has already upgraded. Stop here. You don’t have to do the remaining steps.

4. Login through ssh using program like putty and then copy l4e1_flash and uxfp from /tmp to /home/root
(password same as the admin password to elevate privileges to root)

cp /tmp/l4e1_flash /home/root/.
cp /tmp/uxfp /home/root/.

5. Check file permissions if not executable and owned by root do:

chmod 755 /home/root/l4e1_flash
chmod 755 /home/root/uxfp
chown root:root /home/root/l4e1_flash
chown root:root /home/root/uxfp

6. Upgrade firmware

/home/root/l4e1_flash /tmp/LE910C4-EU_25.20.676_CUST_069_perf_STR.bin

7. After the device reboots, login via ssh and verify that the upgrade was successful.

sudo -s
radio-cmd at+gmr
The command should return the value M0F.670006

Cleanup: Remove uxfp and l4e1_flash scripts from /home/root

sudo -s
rm -rf /home/root/l4e1_flash
rm -rf /home/root/uxfp
