Using STM32CubeProgrammer I can get both NanoVNA-H-SI_v1.2.08.00 hex and NanoVNA-H-SI_v1.2.14 hex to download to the NanoVNA-H4 but only NanoVNA-H-SI_v1.2.08.00 hex will run. DfuSe Demo (v3.0.6) will down load NanoVNA-H-SI_v1.2.14 dfu and the NanoVNA-H4 will run. I prefer the cube programmer, so can anyone resolve this?
