Firmware Changelog

Firmware Changelog#

This lists all the public releases of the FW for amina OCPP charging stations.

  • All public releases are avaliable as OTA updates and follows the semantic versioning scheme (releases including minor and patch increases are always backwards compatible)

  • Only the latest firmware version is available for download

Latest FW OTA Update#

Instructions#

  1. Send an UpdateFirmare.req OCPP message to the charge point with the appropriate link in the location field

    1. Charge points provisioned for LTE or Ethernet only support OTA updates over HTTPS, and the update file must therefore be provided through a HTTPS link

    2. Charge points provisioned for Wi-Fi only support OTA updates over HTTP, and the update file must therefore be provided through a HTTP link

    3. We recommend using the provided links below directly, but it’s also possible to download the files and host them privately. In the case where the update file is hosted elsewhere and the charge point is provisioned for LTE or Ethernet (i.e. only supports HTTPS) the charge point must also have the appropriate certificate provisioned to be able to download the file

  2. We recommend updating chargers to the latest firmware version provided in the link below to ensure that your chargers benefit from the most recent features, stability enhancements, security updates, and bug fixes. We also recommend deploying updates using a “rolling update” approach. This allows issues to be identified early before impacting a large number of chargers

Limitations#

  1. Chargers running FW with a major versions of 3 cannot be updated to FW with major version 4 (a migration is planned)
