Hello, I am debugging a dsp demo in Xtensa Xplorer. It takes about 30 seconds to configure GDB while launching jlink. Is it correct? In addtion, It seems not smooth while debugging step by step.1599785371(1).png

It is my debug configuration. Is there any problem with this configuration? Maybe I ignored some other configurations, so please help me configure it correctly. Thanks!

我也是30秒。我尝试了在Ubuntu下安装xtensa和mcuexpresso,build和下载都OK,但是DSP下载速度还是太慢。我抓取了debug口上下载时的波形,发现每下载27us一个packet,就偷懒休息300us。如果没有这300us的偷懒,下载速度可以提高至少5倍!

Hi,

30 seconds is a bit long. But I think it's fine.  My computer need 20 second to download. I use the default debug configure. It seems the speed is same as your setting.
