+ | ==== MCU wiederbeleben (" | ||
+ | If something strange or unexpected happened to your board and none of the usual procedure are working to install the Bootloader or the Firmware, this might bring life back into your UI. | ||
+ | |||
+ | You will need : | ||
+ | - an up to date STM32 ST-LINK utility ( http:// | ||
+ | - a ST-LINKV2 probe ( http:// | ||
+ | - 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. | ||
