Need SigmaStudio 4.5 (32-bit) for USBi Serial usage

Kitty19 Question

Feb 1, 2026 00:00

I am working with an ADAU1701 SigmaDSP in a product that uses USBi over a serial (UART) bridge implemented by an external MCU (USBiSerialConvAddress). Unfortunately, the 64-bit versions of SigmaStudio do not support USBiSerialConvAddress, which prevents communication with the DSP.

This is a known limitation, and the recommended solution is to use the 32-bit (x86) version of SigmaStudio 4.x, which fully supports USBi-serial.

Does anyone have a download link for one of the following installers? -

SigmaStudio 4.6 (32-bit / x86) - or SigmaStudio 4.5 / 4.3 (32-bit / x86)

This will be used on Windows 10/11 x64 with an ADAU1701 and serial USBi bridge. Thank you very much for your help.

Hello Kitty19,

I will forward this to the programming team to see if they have a copy of this version. So you need the 32 bit version?

This page has Rev 4.6 but only the 64 bit versions.

Thanks,

Hi Dave,

Many thanks for the message.

I require the version of SigmaStudio which supports USBiSerialConvAddress to allow communication with my DSP, from my research I believe 32bit versions allow this. I am looking for SigmaStudio 4.6 (32-bit / x86) - or SigmaStudio 4.5 / 4.3 (32-bit / x86).

Many thanks for your help.

Hello Kitty19,

I received a file from the programming team today. I zipped it up. See if this helps.

I hope there are no issues with me dropping the file into this post...

Hi Dave, unfortunately rel 4.4 x86 will no longer run on windows 7. Do you have any of the below available please?

SigmaStudio_4.6.0.exe

SigmaStudio_4.6.1.exe
SigmaStudio_4.6.2.exe

I'm going to try it on a windows 10 build x64.

Thank you.

Hi,

I'm using "adi_sigmastudio-rel4.6-x64.exe" on Windows 7, and the USBi programmer works.
However, installing this version of Sigmastudio was a bit of a hassle because I had to download a few utilities first, without which the program wouldn't install. But I managed to do it.
I have these files on another computer. I can share them if you'd like.
