SPIM 3 at 16MHz

[siri sam]

Hello,

I'm using SPI 3 to communicate with a NAND memory. I'm able to go up to 8MHz but not more than that. Do I need to set an array list or use the spi manager. 

Is there any exemple of the spi going up to 16Mhz?

Best regards

Have a look at this link, it might help. Also search for SPIM3 for more ..

Hi,

There is no example of SPIM3 with speeds > 8 MHz. It is supported by the HW, but you have to adapt the driver slightly as it only supports up to 8 MHz. Note that that you should read the errata list if you use SPIM3 as there is quite a few issues with it.

Hello,

I have seen the thread  about the SPIM3->IFTIMING.RXDELAY and i've set it to 2 but it doesn't work either.  Do you have more information about how I should adapt the driver? I have activated the anomaly 198 workaround but no success.

Fast SPIM is only functional on the final silicon. Are you using a engineering sample (for instance preview DK) or do you have revision 1? (What is the marking on the chip?)

We are using the revision 1. We also have some revision B but as it is describe on some other thread it seems to works with this one too no?

Anyway all our product are with the final revision.
