From past experiences I STRONGLY SUGGEST you stop thinking in flashing a Siglent FW
Hardware version is the same old as for routerfan and alexitaly: 3-41-1.61.
I'm not set on some specific firmware. If Atten firmware would fix the 2 most annoying bugs (knob debouncing and trigger) then I'm happy.
Even better: with Atten firmware I might keep using 'attenload' tool to get screenshots via USB.
The OP indicates mem depth is 1m x 2 therefore total 2Mpts
Yes it is a 2 * 1Mpts/ch.
I did not understand if there is different firmware/configuration for memory option or the same firmware makes the detection dynamically ?
I just saw in other's pictures that there is another PLD device under the MB (this PLD devices are quite a mystery to me).
Do you know what is the function of each (Cyclone and Lattice) ?
I want to see how to do a backup and this will take some time.
routerfan had a post on JTAG chaining Lattice and Blackfin. But what about Cyclone firmware ? Does it have a JTAG too ?
