Club member Ted (G7OBF), explains the process of updating the NanoVNA. I have never flashed any thing before so was worried about breaking the VNA. I succeeded, and here are the resources and my approach I used. Apparently the main STM program “STM32Cubeprg” will flash from a .bin file but this requires you to entered the start address and that was beyond me, whilst the .dfl file has all the info needed. I chose the .dfu file method The RSGB NanoVNA book outlines the procedure and I found this Wiki more helpful as it has added details https://groups.io/g/nanovna-users/wiki The best YouTube video I found was https://www.youtube.com/watch?v=NcXzITPPTyA Use your browser to download “DFuSE Demo” tool. I choose an English language site as some of the info on the developers site is in Chinese! My Windows failed to select the correct driver for this program, its in file called sttube.inf. To install the driver follow this link for instructions https://groups.io/g/nanovna-users/files/Mis...
