The ctune can be used to configure the crystal (XTAL) frequency tuning value.
The crystal tuning value must be set correctly for every design, which is especially important when making your own EFR32 based hardware.
For the official Silicon Labs radio boards which uses Blue Gecko module and SoCs based the ctune setting is the following:
I have a mix of BGM111 V1 and V2 hardware. Is it possible to build a single image via BGScript that supports both modules?
Thanks for the advice. A few follow-up questions:
1) Does "key 50" = $4032?
2) Is this a special reserver PS Key location?
3) If I wanted to write ctune=270 via BGScript, would the following be correct?
call flash_ps_save($4032, 2, value_data($0E01))(result)
Correction, make that:
call flash_ps_save($4032, 2, $0E01)(result)
