Hi

i.MX6S does not support boot from dual/quad spi, only single spi nor is supported.

Please refer to i.MX6SDL Reference Manual Table 8-23. SPI IOMUX Pin Configuration

for connections for spi-nor.

Thanks。

But ago,someone said solo do not support quad-spi,but support dual spi.

Where is the reference design of imx6 solo? 

Also,I find that solo's RM pdf only has SPI IOMUX PIN configuration table,it is not show solo do not support dual or quad spi.but imx6-quad has quadspi chapter and do not show it support dual spi. I am missing.
