MD5 of File doesnot match data in flash Error with ESP32 S3

I am getting the ```fatal error MD5 of file not match data in flash```. Below is the output of upload.

I am getting the same error while uploading with esp-idf and Arduino ide or platformio.

How could i solve the issue.

What hardware do you use? Anything connected to GPIO45?

[ninjas005]

Yes I have connected an LED to pin 45, running a blink script. I tried using ESP-IDF and Arduino framework. Both are showing same error. I am using a custom board built on ESP32-S3-WROOM-1U.

Yeah, you're likely pulling GPIO45 high. That pin is a bootstrap pin, which when pulled high runs the flash at 1.8V; given that your module has a 3.3V part it doesn't like that. Two options to fix this; pick one of the two:
- Change your PCB to make sure that pin is low on reset
- Use espefuse.py to burn the EFUSE_VDD_SPI_FORCE fuse. This will make the chip ignore GPIO45 and always run the flash at 3.3V.

Yes, Thank you.. It worked. I shorted Pin 45 to ground.
