Singxer/XMOS-audioclass2-driver now at V4.67 -/ firmware-repair on „bricked“ XMOS-devices

so , 😉

many, many thx to our great user „Grigory“  😉 we have now new Singxer/Skysong/XMOS-device-driver at V4.67 ; they are from here ->

(they are also in the forum -> + here ->

but most important and what is absolutely more thrilling is that „we/Grigoryun-bricked a xmos-usb-device/Skysong-bridge !!! 😉

Grigory“ posted the steps + (software-) tools in the comment-section of this post ->

i think the key-point is these github-repository from which u can download/use the python-dfu uploader/downloader which u can also use with other XMOS-devices than Singxer/Skysong; u only have to change the usb-pid-number to the exact pid of your bridge (more in the comments by „Grigory“ (and me))..

->  (+

(a little excerpt->rest see comments->

git clone
cd mic_array_dfu/src

edit xmosdfu.c file and replace string
#define XMOS_XCORE_AUDIO_AUDIO2_PID 0x3086 (for Skysong))

(the Skysong/Singxer firmware (V2.20) („extract“ from my bridge here)->

UPDATE:Grigory“ made a fine tutorial on github about to flash some winbond-chip with a programmer + full „firmware“-packet ->

so, i´m very happy with the whole „procedure“ because this was also a point was originally made for !! (to help other user/people with similar problems !!)

by that, „Grigory“ !! was so nice, and spent a little amount via paypal (u can also do it via the „donation“-button at the right bottom/widgets) to help this blog to stay alive.. 😉

but many greets, stay tuned and take care !! 😉


Raspberry Pi 4B 2GB arrived / Volumio now at V2.714

so, 😉

finally the Raspberry Pi 4B 2GB arrived here->still an improvement in sound-quality and clarity..less jitter, more exact due to more processor-power and when u first power on your raspberry (here with an XMOS-bridge and then via I2S to an ES9038Q2M) u really got the the feel that the Pi is made for music !! 😉 (i think its also because of the short electronical circuits on the board, absolutely low latencies))..

absolutely fantastic, beats absolutely a lot of other DAC/PC/USB-combinations, wonderful 😉

fired it up with Volumio V2.714, its now with a changed UI->

plays here DSD256 without any problems (see other posts here for configuring Volumio with an XMOS-bridge)..->

and because the Pi 4B has finally a Gbit-Lan + USB3.0 (and more Ram + processor-power) its makes now so much fun to browse through your media-libraries and play it („instant“), great 😉

nothing else special, particular by now but many greets and stay tuned 😉

New Skysong-/SMPCB ES9038Q2M-boards + addons..

so 😉 ,

found by chance these new ES9038Q2M-boards..normally i don´t like the other/new boards different from the „green“ SMPCB, V1.06-V1.07 but there are some interesting details with it..

First, on the new, blue SMPCB they use some „DS9281“ for „better coaxial conversion, less jitter, less „lock“-problems, „better coaxial line“, like we know before that the original coaxial-line is not the best->link here-> and here-> , tags AK4118-receiverchip + SRC4192

Link Aliexpress/Ebay(35$)->

second, as said, i don´t like any other ES9038Q2M than the old green SMPCB, „Skysong“ from which had these phenomenal XMOS-USB-Bridge (see other posts before) also made a new ES9038Q2M with a lot of LEDs for the frequency-rate etc..(maybe these i would buy and only because they made such a great xmos-bridge)

Link Ebay/Aliexpress(44$ and up)->LINK

third, there are also some CSR8675-bluetooth->I2S-solutions->(with aptX, LDAC etc..)

Link Ebay/Aliexpress (29$ and up)->

fourth, i still want to buy next a „Topping D50S“ (have to wait a little bit) and next month a Raspberry Pi4 with 2GB and still search some toroidal transformer 15V-0-15V for the green ES9038Q2M here..

more to come and greets for now !! 😉
