micro iDSD BL & micro iDSD – Firmware

With some minor revisions, the iFi XMOS firmware version 5.2 ‘Limoncello’ is ready for public download.

This latest firmware v5.2 ‘Limoncello’ is unified (read: works on the following machines):

• micro iDSD BL & micro iDSD
• micro iDAC2
• RETRO Stereo 50
• nano iDSD

iFi XMOS Firmware version 5.2 is NOT suitable for: iDAC, iLINK, AMR DP-777. So please do NOT FLASH these machines with v5.2.

Non-iFi customers should NOT download this firmware for other non-iFI XMOS devices. This firmware is proprietary XMOS firmware and is for iFi-specified products only. You risk damage to your machine if you attempt to flash your non-iFi XMOS dac with this firmware.

For the micro iDSD BL & micro iDSD:

1) Firmware v5.2 ‘Limoncello’

The very latest in-house firmware[1] version 5.2 for ALL iFi products[2] is available. It is very similar to Gelato v5.1 but there some nice, minor improvements:

i. Small code optimisations.
ii. Fixed issues surrounding DoP standard; including ‘clicks’ when changing tracks and sonic differences to native DSD.

and sub-version 5.2B:

2) This is strictly for Smartphone users ONLY, there is no other reason to use 5.2B on the micro iDSD BL & micro iDSD.
• The micro iDSD BL & micro iDSD will try to recharge while in Sleep Mode (e.g. when connected to a PC). If connected to a Smartphone which is ‘seen’ as a computer, it will recharge via the Smartphone.
• 5.2B disables the Sleep Mode within the micro iDSD BL & micro iDSD; hence it will no longer try to recharge during Sleep Mode and flatten the Smartphone’s battery.
• Do NOT use 5.2B on any other products other than micro iDSD BL & micro iDSD.

Note: As with all such firmware upgrade, there is a risk of bricking your iFi product if something went wrong during the upgrade. If your iFi product is bricked, you need to send it back to the dealer/distributor for repair.

Hence we do not recommend the user to upgrade or downgrade the firmware just for fun. Only do the upgrade or downgrade when necessary.
