Problems with J-LINK Plus to flash a .bin file again to STM32WBA55CG

[ledi7]

Hi,

after flashing the binary files of BLE_ApplicationInstallManager and BLE_p2pServer_ota on the STM32WBA55CG, I can no longer access the controller.

What i did:

1. Flashing .bin file of the BLE_ApplicationInstallManager @ start address 0x0800 0000
2. Flashing .bin file of the BLE_p2pServer_ota @ start address 0x0800 6000

Result: Flashing ok and programm is working

Then I changed the settings in STM32_WPAN configuration (Change BLE Stack from Basic to Full). I generated the code and compiled it.Then I tried to flash the new .bin file of the BLE_p2pServer_ota @ start address 0x0800 6000 and got this message:

However, the controller (STM32WBA55CG) is not listed in the settings:

And therefore, I am no longer able to establish a connection to the controller with STM32CubeProgrammer:

I also checked the COM port, but everything (J-Link on COM7) looks fine here:

Then I tried to establish a connection with STM32CubeIDE, but that also failed:

 

Does anyone have any ideas what I can do?

I have found the cause.

As soon as I set the low power mode in STM32_WPAN configuration to

I have found the cause. As soon as I set the low power mode, I lock myself out. I think I can get access again if I set the Boot0 pin to high as soon as I connect to J-Link.
