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

Kommentar hinterlassen

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 ->https://download.shenzhenaudio.com/Singxer/Singxer_USB_Audio_Class2-Driver_v4.67.0.rar

(they are also in the forum ->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=431 + here -> http://essabre-90xx-rpi.sfb2.com/driver/Singxer_USB_Audio_Class2-Driver_v4.67.0.rar

but most important and what is absolutely more thrilling is that “we/Grigory” un-bricked a xmos-usb-device/Skysong-bridge !!! 😉

“Grigory” posted the steps + (software-) tools in the comment-section of this post -> http://essabre-90xx-rpi.sfb2.com/?p=448#comment-2106

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))..

->https://github.com/respeaker/mic_array_dfu.git  (+https://github.com/respeaker/usb_4_mic_array

(a little excerpt->rest see comments->

git clone https://github.com/respeaker/mic_array_dfu.git
cd mic_array_dfu/src

edit xmosdfu.c file and replace string
#define XMOS_XCORE_AUDIO_AUDIO2_PID 0x3066
to
#define XMOS_XCORE_AUDIO_AUDIO2_PID 0x3086 (for Skysong))

(the Skysong/Singxer firmware (V2.20) (“extract” from my bridge here)->http://essabre-90xx-rpi.sfb2.com/driver/firmware-skysong.rar

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

https://github.com/h0tc0d3/SkySongFirmware

so, i´m very happy with the whole “procedure” because this was also a point essabre-90xx-rpi.sfb2.com was originally made for !!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

Kommentar hinterlassen

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->https://volumio.org/get-started/

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..

2 Kommentare

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->http://essabre-90xx-rpi.sfb2.com/?p=2058 and here->http://essabre-90xx-rpi.sfb2.com/?p=1833 , tags AK4118-receiverchip + SRC4192…

Link Aliexpress/Ebay(35$)->https://de.aliexpress.com/i/32860202632.html?spm=a2g0x.12057483.0.0.580c31f9766Lc9

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)->https://de.aliexpress.com/item/32860202632.html?spm=a2g0x.12057483.0.0.47897ef2tKiCRj

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 !! 😉
