@all
the OS4.1 CD supplied with the Sam440ep-flex board is still the same beta version as shipped with the previous Sam440ep board, which is now several months old.
Unfortunally this beta version shows a few problems when running on the flex board variant which are now cured, or are in the process to be cured, with the latest updates available to OS4 betatesters.
If any customer fells his board may be defective, he could try running Linux on the board (ISO available for download on ACube's web site) to check the full functionality of the board.
