I came to you from an other “audio-device-forum” and hope you can give me a little hint about the following problem, because a lot of customers seems to be affected and the manufacturer SMSL is not very talkative.
- Device USB DAC “M500” from SMSL.
- They probably use the Thesycon “Update Tools” for usb firmware updates for the xmos chip.
- Devices manufactured at the end of last year have a SMSL XMOS USB firmware 1.05 or 1.08 on board.
- Some weeks ago SMSL published an Update 2.1 on their page and withdrawn it some days later.
Customers had try to update there devices. The Update tool shows it has succeeded but the “driver info panel” shows the older 1.05 firmware. The devices still works but it is impossible to update the firmware again an it stuck at 1.05. (So it sounds it has fallback to the initial firmware) Also other update combination (from 1.05 to 1.08) seems to fail at some devices.. all fall back to 1.05
SMSL say the device can only be update once. Is this plausible or why should a “on time update” should be implemented?
They also say the devices must be sand back to manufactory… probably the biggest issue because the devices must be shipped over the halve globe.
Is there any chance to “force” a update by the typical “xmos update tools” so customer can try the updates again?
Thanks in advanced an kind regards.
