I also had a look at [https://binvis.io/ Binvis]. Binvis makes for a stunning visual representation, regardless of anything else at all. I love it. It was fun to see the strings represented in coloured pixels. Also, very apparent to see in Binvis, are the banks. === Firmware Banks - ===This firmware is banked and split. This is to facilitate DFU - the device can be firmware updated by the user while still maintaining stable OS. Then switch a flag to change/denote active bank.
This device has two firmware version strings visible in the firmware (at this point the strings are the only thing I've been able to see)
