Ahh, use?
My two Siglents, my Tek 465 and a Hantek BE6074 (PC scope) all just work. I thought that's how it's supposed to be. :-//
I guess if your goal is to struggle to out do bad engineers, then you are in heaven. However, I buy T&M equipment to do tests and measurements. I realize I might be in the minority in this thread. Carry on..

I have other oscilloscopes both analog and digital and not one. With this just an interest of repair
alias095:
You can also check the signal levels after switching on FPGA_READY, FPGA_DONE,FPGA_RECONFIG?
alias095:
Attach boot log
Can update via rs232?
Or how you can check the operation of the FPGA or buttons?

You have a sample log here:

Update what? The firmware? The standard way of updating is using Platform-tools.
Flash the oldest platform-tools version, the keypad kernel module (/dso/etc/fpga_i2c_kb.ko) is a lot more verbose and shows the activity of any key/knob on the terminal.
If working, you'll see a lot of messages when handling the keypad:
