Hello,
I recently bought a DSO Nano V3, which came with DFU version 3.45. I tried tot update the firmware, following the instructions on the product support page, and ended up getting the thing stuck in DFU mode.
I connected to the board via UART and downgraded the bootloader to 3.29, following the instructions here (Stuck on firmware update screen - #4 by paletochen)
After downgrading the bootloader, the Virtual DFU drive doesn’t work in Windows, MacOS or Linux. In Windows, I get the “Insert Disk” error, and in MacOS, the drive rapidly disconnects and reconnects.
Any advice here? Can the firmware be written via UART?
Thanks in advance
