Here3 u-blox firmware update problem

Here GPS
1

Hello guys!

I’m currently trying to flash the u-blox most recent firmware for my Here3 (1.43), following the tutorial that is described here. Unfortunately, the first time that I tried to do that, the Firmware Update Tool of u-center erased the old u-blox chip firmware and failed in the flashing of the new one. Now every time that I try to flash, I get this “Version Poll Failed” error as you can see in the image below:

u-center_error
u-center_error1920×1030 178 KB

The same behavior happens when I try to use the Legacy Firmware Update Tool of u-center:

legacy_error
legacy_error1920×1030 170 KB

Can someone point what I am missing here? I already tried flashing with u-center 22.05 and 20.10 (no changes with both). Also if Mission Planner 1.3.76 and 1.3.77 with old windows drivers (released in 2020) and most recent ones (released in July 2022)

Can you verify the UAVCAN Passthrough parameters?

Hi;

I have a similar problem. my uavcan passthrough settings are ok. i can connect to the gps via ublox. i tried HPG_130 and HPG_140 roms and the result is the same.

Tridge recently did a video about updating UBLOX over droneCAN, which might not be exactly the same as what you are using, but there could be something in it for you. He notes that selection of baud rates is important, and that multiple attempts could be required.
