Thanks for checking this, however I am a little confused... what do you mean by "don't have FPGA attached" ? Did you unsolder it from mainboard?
insted of complette DSO (in this case DSO5xxxP) i do have only ARM Development board (in this case Embest S3C2416 board),
loaded with dump from original DSO/MSO (in principle ARM dev board, runnig the same Linux as on DSO, with exact the same kernel, dev drivers, and almost the same hardware - except FPGA, ADCs with frontend and frontpanel).
This allows me to run the firmware and watch the connected LCD. The frinpanel of these DSO/MSO models is connected always to FPGA, as i dont have FPGA i'm using my PC to send commands to simulate frontpanel.
So in principle i can test everything, but not the data coming from FPGA/ADC. If i need to do this, i'm flashing the dump to real DSO/MSO. However, i don't have any based on the latest hardware, so all i was able to do is to run the P model firmware, set remotelly avg. mode and depth and watch the LCD. But exactly as i expected, due the missing link to FPGA the firmware was working with no issue.
So it might be a issue within FPGA?
i would say "no", but as this new design everything is possible.
I thought I might have been some functionality to record video of the DSO-screen for educational purposes or something like that.
yeah, that would be nice to be able to record video. Unfortunately it can only play videos, whcih is still good for education purpose, but maybe not something needed by everyone.
I am glad it's no hardware issue with my mainboard and might likely be fixed somewhen. With knowing this bug it can be easily be avoided and honestly I don't really need these settings very often.
nevertheless, i will write it down and send to Hantek/Tekwayx together with other bug reports.
