[solved] CC3200tool flash backup fails - second dump/readout always different

I have a Toniebox CC3200 v1 and wanted to start the Flash procedure. Therefore I wanted to backup the files. The certificates etc I could save via the direct command. When trying to backup the flash the tool does it twice in order to check, but always ends in saying:

“Flash could not be verified, first and second dump are different!”

What can I do that both readouts are the same? I did not move anything meanwhile and tried the command several times with the same output. Wiring should be fine as I could extract the certs.

I shortened the cables at the PCB and now it worked. Additionally I connected SOP2 to the VCC of the UART Board and not of the CC3200.
