Hello,
The easiest ways to program board with .bin, .hex and .srec files is to use J-Flash Lite, which is the part of the J-Link package you installed. The device is R7FS7G2, 4MB. The interface and speed can be kept at their default values. First select chip erase to ensure there isn't any leftover data in flash (even though your new app probably won't access/jump to it). Then point to your image and program the device. By default, e2studio produces srec file as build artifact and you can find it in the Debug folder of your project.
Regards
