Can I flash esp-1mb-at firmware onto ESP8285N08 (8Mbit flash)?

[thevien2507]

Hi,
I’ve successfully flashed the esp-1mb-at firmware onto an ESP8285H16 module (16Mbit = 2MB flash), and it’s working well.

Now, I’m planning to use the ESP8285N08, which has an 8Mbit (1MB) flash chip. Since the firmware I’m using is the esp-at-1mb variant, I’d like to confirm:

• Can I safely flash this esp-at-1mb firmware onto the ESP8285N08?

• Are there any constraints I should be aware of (e.g., partition offsets, OTA limitations, feature reduction)?

Thanks in advance for your clarification!

I am not sure the size of your ` esp-1mb-at firmware`. If it is indeed 1MB, then ESP8285N08 works exactly like ESP8285H16.
The only different might be that ESP8285H16 is better suited for high temperature environment.
