Preparing for STLink Flashing

Setup-Banner

Disable readout protection as shown in this video:

R9MM/Mini

Connect the STLink V2 into the pads shown below: 3v3, GND, C = CLK and D = DIO.

r9mm/r9mini STLink connection

R9MX

Connect the STLink V2 into the pads shown below: 3v3, GND, C = CLK and D = DIO.

r9mx STLink connection

R9Slim

This RX requires an StLink v2 to be flashed.

Wire up the RX to the STLink using 3v3, GND, CLK and DIO.

r9slim STLINK connection

Wiring the R9 Slim+ for STLink flashing will be the same

Jumper R900 Mini

This also requires an STLink, so the wiring is as follows: Wire + = 3v3, - = GND, C = CLK and D = DIO to their respective pins on the RX from the StLink.

Because those pins are so small one option is to only solder a wire on the CLK and DIO then power it with the 5v pin with an external power source.

ES915RX (Discontinued)

ES915RX

Connect your STLink into GND, DIO, CLK, 3V3 of the receiver. These pads are marked clearly as in the image above.

Use the Navigation Menu to proceed to the Flashing Guides for these Receivers (under the section Flashing Receivers).
