-==== MCU wiederbeleben ("un-brick") ====
-Eine nicht mehr funktionierende OVI40 MCU kann - sofern es sich um keinen Hardware Defekt handelt - auf 3 Wegen wiederbelebt werden:
-  - via USB-Stick (.bin-Datei)
-  - via DFU und USB-Kabel (.dfu oder .bin - in letztem Fall musst Du die Startadresse mitgeben 0x810000)
-  - via ST-Link (.bin-Datei - auch hier musst Du die Startadresse wie bei 2) angeben)
-Die Dateien dazu finden sich [[uhsdr:uhsdrdownload|hier]].

-=== USB-Stick Methode ===
-=== DFU & USB Kabel Methode ===
-=== ST-Link Methode ===
-Benötigt wird:
-  * STM32 ST-Link Programm
-- an up to date STM32 ST-LINK utility ( http://www.st.com/en/development-tools/stm32-programmers.html?querycriteria=productId=LN2013 ) running on something (you choose)
-- a ST-LINKV2 probe ( http://www.st.com/content/st_com/en/products/development-tools/hardware-development-tools/development-tool-hardware-for-mcus/debug-hardware-for-mcus/debug-hardware-for-stm32-mcus/st-link-v2.html ), (you might use some other compatible hardware)
-- latest version of the Bootloader and/or UHSDR Firmware
-The only tricky part is to connect the probe JTAP connector to the JP8 UI board, here are the needed wires :
-JP8-3 (SWDIO) to JTAG-7
-JP8-4 (SWCLK) to JTAG-9
-JP8-5 (UI_3V3) to JTAG-1
-JP8-6 (GND) to JTAG-20
-The rest of the procedure is straight forward : connect, erase, flash and you are done.
-One additional trick, when I first connected to the MCU, I got an error message « Readout Protection Mode » and was unable to erase the chip. I finally choosed to try to flash a first time and the utility did what was necessary to remove the protection mode. Cool, thank you STM !

-A couple of us faced the same issue during beta testing the new UI board.
-But as you could see a cheap chinese ST Link adapter from Amazon or eBay saves your day
-Here are the steps. Unfortunately in German but maybe it helps.
