Hello, I have a been looking a solution to provide highest possible NAND Flash interface. imax8m itself having limitation to support TLC etc.
From the application processors manual,
eMMC => DDR mode can support up to 400 Mbytes/sec whereas raw NAND can support up to 200 Mbytes/sec.
Looks like eMMC is faster than raw NAND.
I am not clear on the ECC etc. Which interface(eMMC or raw NAND) will be having better throughput?
Yes, you are right, the SD/eMMC interface of the i.MX8M processor is faster than the Raw NAND interface.
For SD/eMMC devices, all ECC and other required processing is perfomed within the device, so, there are no special features required from the processor.
Have a great day,
Artur

Hi Artur,
Thanks for your information.
Is there any application note explain about these information.
I am interested to know the throughput of raw NAND or eMMC. I would need
to select the device which is having better throughput.
