Here is a slight documentation update. The biggest new thing is a mention that this firmware requires at least VSOS 3.27 to work.

Hello!

Here is a minor update for VSOS 3.57 that we released just a few days ago.

One change is that the solution AmpBConf included in this package can now be customized so that the user can tell which pin acts as the SD card's power regulator control pin. So, while the default is still 0x07 for GPIO0_7 that is the VS1005 control pin for the SD card regulator on the Amp Board, you can now use e.g. 0x23 for the VS1005 Breakout Board v2.1, which uses GPIO2_3. See file solutions/AmpBConf/README.TXT for details on how to use it.

I hope this update proves useful!

Kind regards,
- Henrik

Oh,

please note that the new version of AmpBConf of the previous message is not yet part of the VSOS 3.57 Root Images and Libraries package because that was released already a week ago. So, if you want the new functionality, download AmpBConf.dl3 from here until the next VSOS release's Root Images and Libraries are released.

Kind regards,
