SigmaStudio+ download signal stream prompt "Target execution could not be verified"

Are you running the target application on the hardware every time by resetting the board before downloading the schematic project ?

If reset the board before downloading, it can download normally. But that's unacceptable, because tuning requires repeated downloads. In addition, when the download is finished, I control the volume, mute and other components, DSP will crash. Why??

Why is there no reply?

SigmaStudio not supporting repeated download. The audio data processing happening once download completed and SPORT running to received/transmit data through ISR. There is core exception happening when we download the schematic during the audio processing due to data buffer usage in ISR. 

I cannot accept your explanation. When the schematic diagram is relatively simple, it can be downloaded repeatedly, and SigmaStudio can also be downloaded repeatedly, but now SigmaStudio+ can not be downloaded repeatedly.

Hello, working with SS+, i have now the same problem as discussed, i could download continue by TCPIP to the board, now it stop and give the message 'sigma studio plus target execution could not be verified', can someone helps me what is wrong here ?

Kind regards

Hello, I use USBi(SPI) to download the schematic. The cause of the error may be SS+(you can update to the latest version) or a problem with the ADSP21593 framework.
