In camera web server example. I noticed, if the SPI mode is QIO following error is generated.
rst:0x3 (SW_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)
This does not happen when SPI mode is DIO. As far as I know, QIO provides better throughput. Not sure if this is a hardware design limitation.
Please confirm.
Correct mode depends on your flash chip. Most are QIO compatible. QIO has double the throughput of DIO, but at the same time DIO@80MHz == QIO@40MHz
