ALR LoRa firmware for home assistant enabled AUTO DISCOVERY

[maso]

Hello, I have problems to write code and now I need to test original firmware.
While uploading my installed code is not removed.
The flash tools says finish, but I hear the my old code (which reboots ever second) was not overwritten.
-----------------------
In the flasher cmd windows I see following prompt:
Uploading stub...
Running stub...
Stub running...
Changing baud rate to 921600
Changed.
NO XMC flash detected!
SPI_BOOT_CRYPT_CNT 0
SECURE_BOOT_EN False

is stub and send flash finish
-------------------------------
it detects following info:
AP: DCDA0C7B7EE5 STA: DCDA0C7B7EE4
BT: DCDA0C7B7EE6 ETHERNET:
---------------------

The display keeps dark.
Any Idea what I should do?

Thanks, Martin
