What platforms did you test DDR mode on?
I have tested DDR mode with exynos board.
I tried this on an Freescale i.MX6 based platform but the driver returned error
code COM_ERR (-18) when trying to switch to any of the DDR modes. I guess the
fsl_esdhc.c driver needs some adaptation for DDR to work.
I didn't know how work DDR mode at fsl_esdhc.c.(If you share the host
controller TRM, it's helpful to me.)
Host controller also need to change the DDR mode.
I wonder your board didn't work not to enable the DDR mode?
Thank you, yes the fsl_esdhc.c driver does not yet support enabling of DDR mode.
I think it should be easy to implement, I believe it is just a question of changing
the clock frequency.
Best regards,
