OmapL138 add a second SPI NOR flash device on ChipSelect 1

Other Parts Discussed in Thread: OMAPL138

Hello,

 

I need help to add a second SPI NOR flash device on chip select 1. Omapl138 Logic PD EVM reference design comes with a 8MB SPI NOR flash on CS0 of SPI1 bus.

In my custom design I replaced this flash by a same type one but 16 Mb sized. All works fine. I want to add a second 16 MB chip on CS1 of SPI1.

I do not understand what I have to modify in the kernel to manage this second device.

I had already managed all the PINMUX stuff.

Any help is welcome.

Thank you

 

Gilbert Brisset.
