Hello, I am getting an error while writing to flash. I've attached the error message. image (4)

What could be the reason for this? Could you help to solve this issue? Many thanks.

Interesting! Looks like some type of off by 1 error.

Can you double check exactly how large the data is you're trying to program? Could it be 1 byte shorter or longer than intended?

If you're able to zip the file and attach it as a comment, I could take a closer look

Thank you for your quick response.
Nor Flash Memory Manufacturer: Zetta Model: ZD25WQ16 Size: 16Mbit Bin file size: 62kb The data size is very small compared to flash size. I've attached the file. demo_V2.0.23_20240726.zip

Thanks a lot.

In addition, I've also tried using a few other bin files. I got the same result.

Thanks @faaytekin! I'm happy to take a closer look. When you get that error message, can you expand the "details" button and copy/paste the long error message here? That would really help. Thanks!
