Error when I try to program LoRa-E5 STM32 board with stm32CubeProgrammer and st-link/V2

[SBaro.11]

Hi all,

I've bought this board https://wiki.seeedstudio.com/LoRa_E5_Dev_Board/ and for now I try to create my own program with stmSDK. But I hae an error when I try to erase AT firmware give by Seed. I've connect my ST-LINK/V2 to the board like it said in the wiki with SWD. But when I run STM32CubeProgrammer I encoutering an error `No STM32 target found!`. Before clicked in connect button I hold reset button on the board. I've upgraded my st-link/v2 firmware

I've followed this procedure https://wiki.seeedstudio.com/LoRa_E5_Dev_Board/#2-develop-with-stm32cube-mcu-package

Check cabling, check power.

Hold a RST button while you click a connect button on STM32CubeProgrammer.
