I really see no point in kicking the can down the road We don't know the speedbin fuse register and the values applicable for this IoT chipset. Currently, there is only a single variant and no SKUs for this chipset. We can add them when those decisions are taken by the relevant folks from Product team. -Akhil. > > Konrad
