Please clarify the meaning of '"program". Do you want to debug your firmware or download the firmware? I am not sure about your requirment.

Hi Geetha,

No. You need the control center to program FX3.

Hi Geetha,

I don't know the reason why you want to download firmware into RAM through segger. It is feasible when you debug your firmware with segger becasue it will download firmware into RAM.

However, I presume that it doesn't make sense since an USB device could only work when it is connected to an USB host. The firmware will not run if FX3 is not connected to an USB host. Once you connect FX3 to host, programming from USB port is an easy and fast way when compared to segger Jtag.

As for the SPI flash, you could download firmware into it using control center in development step. The third-party programmer could be used when mass manufacture.
