Bring up of new platform using TeseoIII

[Dror]

I am trying to bringup a new platform with TeseoIII.

I manage to flash the firmware, erase etc. However, when using Teseo-Suite, i can see 1-2-3 satellites recognized and a short few seconds after being visible on the Signal level window, they disappear.

Are you familiar with this behavior? What could be the cause?

Found root-cause.

A small 0201 size ferrite-bead was used in series to VINL1 power input. This caused a drop in 1.8V supply when GNSS engine started to work towards a fix, this probably caused the internal engine to reset.

Replaced the bead with 0 ohm. Issue resolved.

Perfect.

Less work for me 😉

For any question feel free to ask.

If you can could you share some info on your TeseoIII project (you can write me directly francesco.virlinzi@st.com)
