Hi Grant,
we have 2 ET 4l, one working and passing the readiness check and one not.
1. SN: IS423-103108020545 with Firmware 2.41.0-f2dc56e which is working fine with our code and pass the readiness check.
2. SN: IS423-103109431303 which with Firmware 2.16.0-bff79b6 is not working with our code and doesn’t pass the readiness check.
It seems to be a Firmware issue, How can we upgrade the 4LFirmware to 2.41.0 ?, Is there a tool for upgrade the 4L Firmware ?
