 +==== ET7 firmware reflash ====
 +
 +myCNC-ET7 reflashing procedure may take up to 3 minutes.
 +
 +To reflash the board:
 +
 +1. Plug in the 24V DC power supply
 +
 +2. Plug in the micro-USB cable into the ET7 controller & a Host Computer with myCNC installed
 +
 +3. Close jumpers J5(reset) & J6(programming) on the controller board
 +
 +4. Open (remove) the J5 jumper.
 +
 +{{:mycnc:et7-reflash-001.png}}
 +
 +5. Open myCNC software on Host computer (Settings > Support Tab)
 +
 +6. "Select board" set to "myCNC-ET7"
 +
 +7. Select "Firmware version" from "Release", "Night build" or "Testing" ("Release" is recommended)
 +
 +8. "UART port" - select the port with FT232 attached. If no such port visible, check the micro-USB connection, then close and open the Support tab once again in order to refresh it. 
 +
 +9. Baud Rate set to "115200" for ET7; other baudrate can be selected in case of problems on the 115200 speed
 +
 +10. Press "Update Firmware" button, Firmware download and reflashing process will be started
 +
 +11. If "Sector 0; +" message is shown in the debug window, the reflashing process has been finished successfully.
 +
 +12. Remove all jumpers (J4, J5) and restart the board.
 +
