TMS570LS3137: TMS570LS3137 MibSPI Interface: Slave mode Receive group not complete

Kalyan Vagvala61

Part Number: TMS570LS3137

Hello,

I am using TMS570LS3137 micro-controller for one of our application in slave mode. With transfer group#0 enabled, i am expecting a group of data (specifically 48 bytes). i always see either few bytes missing or the order of data different from that of sent. what could be the reason for this.

Thanks in advance.

Regards,

Kalyan

Hi Miro,

Thanks for your response.

Issue is resolved now. i have been continuously transmitting data over SPI bus if not seeing Receive TGINtFlag set. After removing the transmit code i am able to see whole SPI packted in receive buffer.

Thanks,

Kalyan
