Does the flash drive have to be specially formatted before the RGL file is loaded onto it? Also, is there a special process to burn the file to the flash drive, or is it as simple as drag-and-drop?
I used a flash drive formatted as FAT32.
I suggest you the following steps...
1- format the flash drive as FAT32;
2- to check the compatibility of the flash drive, insert it into USB socket of scope WITHOUT upgrade file, and try to save some tracks;
3- compute the md5 checksum of upgrade file on your PC;
4- copy (e.g. drag-and-drop) the upgrade on the flash drive; leave only the FW file in the flash drive;
5- compute the md5 checksum of upgrade file on the flash drive still into your PC;
6- eject the flash drive, re-insert it again in the PC (in a other PC is better) and compute again the md5 checksum. This last md5 checksum must be the same of the steps 3 and 5;
7- eject the flash drive and insert it into USB of scope;
8- at prompt 'Upgrade" chose OK and wait.. uhmm... 2-3 minutes. Don't touch the flash drive, of course!
Protects the power supply of scope by UPS, if any!
