Quad SPI availability with iMX6

Hello,

I would like to know if there is any possibility to have a Quad SPI (or QSPI) interface with an iMX6Solo in order to have a faster access to SPI NOR.

The datasheet offers 2 single data standard SPI interface with 4 chip select pins,

and several SDIO interfaces with 4 to 8 bits data bus width.

In the SABRE Platform for IPTV based on i.MX 6  Block Diagram

2 QSPI are mentionned but nothing else.

Does anyone could confirm if it is possible to have a Quad SPI interface ?

Thanls for your help,

Regards.

The current i.MX6 products (6Quad, 6Dual, 6DualLite, 6Solo and 6SoloLite) do not support QSPI. This appears to be an error in the presentation.

According Freescale news :

http://media.freescale.com/phoenix.zhtml?c=196520&p=irol-newsArticle&ID=1917475&highlight=

iMX6SoloX will provide the feature plus :

Additional features of the newest i.MX 6 series processor include:

  • Dual-port gigabit Ethernet audio video bridging (AVB) for quality-of-service in automotive and other applications with enhanced traffic shaping and packet prioritization.
  • Cost-effective 2D and 3D graphics processing unit (GPU) for enhanced HMI development.
  • Flexible boot options, including support for quad SPI and raw NAND, and a memory controller that interfaces to both DDR3 and low power DDR2.

Bruce or Clay ??

Thanks for this clarification. Do you expect to have a future firmware revision with Quad SPI integrated in the chip ?

Starting from USDHC peripheral should not be too complicated to offer a Quad SPI bus to your customers.

Yes. A future chip will have a dedicated Quad SPI peripheral (implemented in hardware not in firmware through another interface).

Will this chip be pin to pin compatible with current iMX6,

and when do you expect to propose such component ?

As per described in the mx6 solo reference manual, it contains the standard ECSPI block.
