ESP8266 Community Forum

- Thu Apr 21, 2022 3:18 pm #94353 Does anyone know if it is possible to boot ESP8266 without any SPI flash for example, boot from UART and feed program directly into RAM and execute from there.

- Fri Apr 22, 2022 4:01 am #94354 As far as I know there are only 2 boot modes: from flash or from SD card, although I've never never seen anyone venture the latter option (it might not be even possible at all).

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.

Ah, learnt something new today.

Thanks Pablo.
