About SPI-I/F control for MX28.

Dear All,

 

Currently, my customer is developing the product using i.MX287.

 

Their board has SPI-SRAM.

It is connected by using SSP as SPI-Master mode.

 

Though SPI access works correctly, it halts operation rarely.

 

Their program waits for HW_SSP_CTRL0_RUN bit = 0, in order to check whether transfer was completed or not.

However, it is not rarely set to 0.

 

Is polling HW_SSP_CTRL0_RUN bit = 0 correct in order to detect the completion of transfer?

Please let me know if you came up with something our mistake.

 

Best Regards,

George
