GW-ETH-02A
Firmware upgrade / Bootloader
GW-ETH-02A has the bootloader implemented to upgrade the FW by a new version released by the IQRF
manufacturer (
gweth.hex
file). There are two ways for FW upgrade:
•
Store the
gweth.hex
file to the SD card using the internal web server (via Ethernet). Then the GW performs reset
automatically. See chapter
FW upgrade
above.
•
Store the
gweth.hex
file to the SD card (in the root directory)externally (e.g. from PC using an SD card reader),
insert the card into the GW and reset the GW.
After the reset the upgrade procedure starts.
•
If the upgrade is completed, the GW will then be started with the new FW version. To make sure that the upgrade
passed successfully, check the current FW version e.g. via the internal web server.
•
If the upgrade fails during the
FW checking
phase, the GW will then be started with the original FW version.
•
If the upgrade fails during the
FW writing
phase, neither the original nor the new firmware is ready and the GW
stays in the
Start-up
phase. Then, recovery is possible only by FW upgrade from SD card. The user should restore
the
gweth.hex
file on the SD card before starting the recovery.
See chapter

(
Firmware upgrade
and
Run operation
) for possible states.
