New bench scope - Fnirsi 1014D, 7", 1GSa/s

Can you remove that line from firmware for that chip? I do not have knowledge for that.

pcprogrammer:
Actually that is what I just did :-DD

The attached file is from last October 6th. Rename it to FS-1014.bin and load it on the SD card. The scope checks on startup if this file is present and will then write the flash with this data. If all goes well of course. This is the normal update procedure of FNIRSI

I have not tried it on my scope.

For those interested, what I did is change 4 bytes at location 0x04B330 from 0xFB, 0xBD, 0xFF, 0xEB to 0x00, 0x00, 0xA0, 0xE1. This changes a bl xxxx instruction to mov r0,r0.

I looked at your fpga bitstream and at least the header looks to be correct. Don't expect any problems there, but you never know.

The se98 does not match the behavior of this "special ic" judging by the software. It is a bit strange that they left some marking on it. The three FNIRSI scopes (2x 1013D and 1x 1014D) I have don't have any markings on these ic's.

If the modified firmware I posted changes what your scope does I will make some more modifications to see if it is possible to make it work without this "special ic"

Edit: The SE98 also has a dedicated I2C address of 0x30 to 0x37 and not 0x00 which FNIRSI is using for this special ic.

joseph4511:
everything stand still. Stucked on logo, takes 1.1 amps from supply. Can you replace the lines from whole firmware ?

pcprogrammer:
Sure.

I expected it to show the scope screen and then hang, but there might be a call to the translate function before.

Hopefully this will have the scope continue, but it will not function as intended. I just disabled the call to the special ic without taking the needed actions on the data. When this indeed continues into the scope screen I will make a patch to make it work without the "special ic".
