MPC5744P Signal SPI Recovery based on MCAL

Hi,

 

My customer used MPC5744P SPI master to communicate with TCAN4550 based on MCAL, the SPI baud rate is 10MHz. While the CAN FD bus load increased up to 80%, the SPI sequence will be suspended, and can’t be cancelled.

SPI De-init will re-initial all SPI modules. Customer can’t receive such operation. Do we have solution to recover singe SPI module only?

 

BR,

Hornby

Hello,

The customer can use Spi_Cancel to cancel the current Spi operation. Make sure that he/she needs to enable SpiGeneral/SpiCancelApi

Best Regards,

Nam
