CC 6UL starterkit setup

Hi,

I just opened my digi CC starterkit and I’ve get stuck right in the beginning. I’ve followed this tutorial https://www.digi.com/resources/documentation/digidocs/90001548/#task/yocto/t_program_firmware_yocto.htm%3FTocPath%3DDigi%2520Embedded%2520Yocto|Get%2520started|_____3. I’ve put the decompressed files (not the folder) in the SD root, I don’t know if the folder is required though. I can see the RX LED on the board blinking when I press any key, so there is data being sent. However, when I press the reset button on the board and any key of my keyboard, nothing happens on my serial terminal even though I should see a U-Boot bootloader prompt message.
