IMX7D Qspi change clock issue

xujibin — Thu, 10 Aug 2017 06:30:55 GMT

I used a serial flash on IMX7D target board, when the spi clcok is 29M, It works well, but when I change it to 84M,

read data error,IF I write data at 84M and read it at 29M, it is ok. But if 84M write data and 84M read data, It faild.

So ,if I change the spi clock frequence, what othre parameters should I change at the same time for the quadspi controller?

Hi,

About the i.MX7D qspi clock setting you can refer to the reference manual IMX7DRM.pdf.

Have a nice day
