3. Board boot up
3.1. MFW
MFW is based on default.ELF file.
Note : That currently the FW is to be pushed from the Laptop and hence requires a dedicated Laptop per
UE to be used at all times. Bootup procedure below needs to be performed everytime the UE is USB
Powered down or Reset is performed.
3.2. BAT file for FW flashing
Please contact your Sequans POC for Batch file to Flash the UE & Latest FW
Firmware file (*.elf) should be renamed to default.elf & be placed under
SQN_CATM_DM_STP_V0.3\SQN_FW_Load\Firmwares ( Please unzip the Batchfile to get this location.
Note this folder can be placed & run from anywhere on your PC, however it is important that *.elf file be
placed inside the Firmwares folder)
Note : Firmware file & Bootloader both are both in *.elf but can be differentiated by size.
Firmware file is approximately 3+ megabytes while the Bootrom will be approximately 1.5 megabytes
3.3. Bootup

3. On UE press on the Reset button to have UE loading the bootrom and to be able to load the
firmware
4. Copy your *.elf into the folder "SQN_FW_Load/Firmwares" with the name "default.elf"
