DPO4104 firmware upgrade
I'm trying to upgrade a DPO4104 oscilloscope, the instructions in the website seem quite clear:<br> <br> 1. Download the latest firmware version in a suitable pendrive.<br> 2. Copy the *.img file in the topmost folder.<br> 3. Power off the oscilloscope and connect the pendrive.<br> 4. Power on and let it do the magic<br> <br> However the firmware process does not start. It powers on as no pendrive is connected. Ive also verified that the pendrive is compatible (by saving data from the oscilloscope).<br> <br> Any idea of what is going on?
