V1.1.0 / 11-November-2011

Main Changes

  • Add the possibility to enter a non integer MHz value for HSE crystal and HCLK clock frequencies.
  • Add constraint on the RNG and SDIO clock (max 48 MHz) when the USB is not used ("Require 48MHz for USB OTG FS, SDIO and RNG Clock" option disabled)
  • When the USB is enabled ("Require 48MHz for USB OTG FS, SDIO and RNG Clock" option enabled)
    • Only the HSE can be used as PLL and/or System clock source
    • When it is not possible to have 48 MHz with the target System clock frequency, a message window appear and display the nearest system frequency allowing to have 48 MHz, then user can select to accept or not this configuration.
  • A progress bar is added to inform about the progress of the clock parameters searching.
