Other Parts Discussed in Thread: IWR6843ISK
One issue I have noted on several occasions is that when using a Lua script in mmWave Studio to load the firmware, if the script is run a second time a progress bar will appear when downloading the MSS firmware and never progress. Obviously there is no specific need to load the firmware twice but it is convenient to use a single script to run the radar and edit parameters before running it a second time.
As demonstrated in the code below, it occurs when loading the MSS firmware for a second time only after having loaded both the BSS and MSS first. It appears to be due to a BSS firmware mismatch error that occurs when the BSS is loaded for a second time after both the BSS and MSS have already been loaded once.
Note that I have also tried this on mmWave studio 2.1.1.0 with the same result too.
Why does this occur and how can it be prevented?
