MPC5748G as SPI slave node, high baud rate will cause data error

We use MPC5748G as the SPI slave node, no DMA, and IB mode. The baud rate can only be used up to 1M. Data with a baud rate higher than 1M will cause an abnormality. Does the chip have this limitation? Or is it a limitation of the MCAL software? Or is it the reason for our EB configuration? We look forward to answers.

Hello @jacst ,

 

As far as I know, we do not have this limitation. Could you please share your configuration (.epc files) and the MCAL version. So we can try to check it.

 

Best regards,

Hung.
