Hello,
customer asks: "Is it possible to read out installed EBoot and NBoot?
Yes this should be possible:
NDCUCfg/NDCUCfg Library offers commands/functions „boot read <type> <pfad>/NDCUCFG_CmdBootloaderRead (DWORD dwBootType, LPTSTR pMsg). Where type=0 is EBoot and type=1 is NBoot. PSD-Data (EBoot settings) can be retrieved via „psd read <pfad>/ NDCUCFG_CmdPSDRead(LPTSTR pMsg).
BTW: maybe it is sufficient for you to know the installed versions. You can find them in the serial boot messages or in the Registry under HKLM/platform. Binaries of all verions are available in the board specific download area.
