Hi,
I have been successfull on programming to LoRa-E5 mini with ST-LINK V2 clone. First of all ı was getting an error like yours then, I downloaded the STM32CubeProgrammer when i try to connect the LoRa via St-link, I got an error again. Then i try to holding down the RESET button and press the boot button just once. And then I succeed to access the card.
