3.6
Firmware including updates
The FlashMic firmware is held in non-volatile memory and two copies are kept in
memory to ensure that operation is still possible even if the currently in use
firmware somehow becomes corrupt.
3.6.1 Firmware problems
Generally, most booting, freezing or locking up problems have been due to the
earliest release of firmware, v3.02.10, which could corrupt the flash memory file
system if the batteries were allowed to run flat in the mic. This bug was removed
in an update to v3.02.12; all microphones should have been updated at that time.
The current firmware is v5.01.08, which contains a still more secure file system.
The firmware for the FlashMic may be updated from time to time and the latest
version will be available for download from the website:
www.flashmic.info
3.6.2 File corruption
FlashMic’s with "corrupt" files systems (and, indeed, any FlashMic) should be
reformatted and then updated to the latest firmware. All data will be lost.
There are two operator recovery options (first fit fresh or fully charged batteries).
Try ‘A’ first:
A. Hold down the REC and M buttons whilst powering on. The display will show
DRM85 and go no further. Move the rocker switch up or down. If the display
shows SAME, them remove the batteries and start again, but move the rocker
switch in the opposite direction to before (i.e., turn switch up if the switch was
turned down before). The display should show UPDATE, with a progress bar. If
successful, note, the firmware version, and then perform a forced format, as
described in ‘B’ (backup any available data first)
B. Forced reformat. Hold down REC, PLAY and M buttons whilst powering on. The
display should show DRM85, then the firmware version, then "FMT N" Use the
rocker control to select "FMT Y" and press in to select (all data will obviously be
lost).
Assuming you manage to re-update in ‘A’ and successfully reformat, then update
the firmware to v5.01.08 (or later if available). Do the update twice!! (as stated
above, the Mic holds two copies of the firmware; you are choosing between the two
copies in ‘A’ above, so it's important that both copies are updated).
3.6.3 Firmware revisions
The latest version of firmware is always available from the download section of the
website www.flashmic.info.
3.6.4 Pre Production FMO units
Units marked FMO, either on the box or on the microphone label, are pre-production
prototypes. They are NOT suitable to be used be any of the released versions of
firmware and should be returned to HHB!
