Expected behavior

I expect to see the log wifi_init_softap finished. SSID:myssid password:mypassword

Actual behavior (suspected bug)

Instead, I only see up to phy_init: failed to load RF calibration data (0x1102), falling back to full calibration. I

Additional context

The hardware is an ESP-01s and being programmed using Arduino Nano. I am able to flash the firmware to the device but is stuck on the RF calibration log. I'm thinking it might be a hardware issue, but I tried on another ESP-01s and I get the same result. I also flashed a blink code into these two devices and it works.

Would appreciate any clues regarding the issue, thanks!
