Boot from HSPI

Postby smarly » Tue Jan 19, 2016 6:22 pm

Hi,
is it possible to boot from a SPI flash on HSPI interface ?
If so, is it possible to download this SPI flash using uart boot mode/espressif download tool ?
Thanks for your help.

Hi smarly,
When external SPI flash has been moved to HSPI interface, ESP8266EX can only worked as SDIO/SPI slave and needs to be connected to SDIO/SPI master.
You can refer to "8H-ESP8266__Interface_SDIO_SPI_Mode" for details.
