I just updated from v1.4-177 to v1.4-185.

?

None of my 50 or so config presets on SD card will load and instead pop up "Format err".

?

I am guessing the file formats have again changed as happened with v1.4-145.

?

Apologies if I missed discussion on this when I searched the forum.

?Peter,

If you do not need the changes in the later FW you better stick with the old FW

Erik, can you detail specifically what changed in file format/content if minor? Might be quicker for me to write a program to update the files versus redo them all. Would like to stay with latest versions. Thanks.

The saved settings are binary files copying bit by bit the internal data structure of the settings data.

There probably are one or two new settings data inserted into that structure making a bit larger but fully incompatible for loading.

I considered saving the settings in ascii but have not yet done so as it's a lot of work.

Adding some bytes in binary won't work as there is a checksum and a magic number to protect the data

I did it this way:

- reload old FW, then restore config

- get all correction tables with the tinySA app (pc): in tinySA comms use a Commands button

- edit one command, and insert all correction requests

correction low

correction lna

... insert all correction commands

this way the tinySA sends all correction tabels with 1 button click

- save them in a file

- in excel / libreOffice remove the timestamps and rx tx labels, to get the naked correction data, e.g.:

correction ultra lna 0 30000000 0.0

- copy this naked data block back into tinySA app (edit an other command button)

- now make the tinySA FW update etc ...

- from the tinySA app send all correction tables with 1 button click
