Bootloader upgrade for old eWON

Since firmware version 5.2, the Bootloader of the eWON must be greater than 2.0.

Every eWON produced with a serial number greater or equal to 0648-xxxx-xx has already this bootloader 2.0.

To upgrade to 5.2 an eWON produced before 0648-xxxx-xx, the bootloader must be upgraded.
1. Your eWON MUST be in 5.1 firmware version
2. Download the bootldr.bin file in the eWON by FTP.
There is no need to reboot after the bootloader upgrade.

The eWON data and config are NOT affected by this upgrade.
Important: You should not remove the power during a bootldr upgrade.

more information in the General User Guide (chapter 9.5)

Extract bootldr.bin from the bootldr2_4.zip file and put it on eWON FTP root.
