RT1176 SEMC Clock

[chrisgulick]

I recently designed an RT1176 system. It uses the SDRAM controller. I can run the example driver app and memory passes read / write tests. I would like to run the memory at 166MHZ. The clocking tree is quite complex and is difficult to get a handle on in short order time. Would someone be able to tell me how to change the memory clock to 166MHZ.

Thank you

Hi @chrisgulick ,

You can use config tool to configure the clock.

Jingpan,

Thank you. Went into SEMC clock root and changed SDRAM clock to 166.73MHz.

Memory runs with no errors.
