DSO firmware version 3.64

Hi,

I upgraded my DSO 201 V3.21A with the Benf 3.64 via .hex method.

BUT now, when I inserted the sd card 2Gb FAT16 with a FILE000.DAT >1Ko, the screen is freezed on “System Initializing Please Wait”.

Why ?

I bought this oscilloscope to be able to save the data. (Is it possible to record for long time ? in dat, csv or txt file ?)

Why the Benf firmware cannot recognize my sd card ?

Thank you.
