[omidg2]

Hi, I use ESP32-S3, I flash nanoframework image to it by this command line:
nanoff --masserase --update --target ESP32_S3_BLE --serialport COM5

the result is:
Connected to:

Features WiFi, BLE
Flash size 4MB unknown from TENX (manufacturer 0x94 device 0x16406)

but when I connect my device to putty with baudrate 115200 and start it, it seems nanoCLR not start correctly, anyone can help me?
