DM814x PCIe TLP configuration

Radhakrishna Gotur
Prodigy 95 points

Hi,

 

I am using two DM814x evm one set as RC and other set as EP.

I am able to perform memory write transaction either ways(from RC to Ep and vice versa) through address translation.

But, I am unable to do transaction with payload size more than 1DW(Data word). How I can issue memory write transaction with data payload more than 1DW?

There is a configuration register to set MAX_PAYLOAD_SIZE. Is there any way to configure PAYLOAD_SIZE?

And also is there any way to configure the transaction type on the out going TLP(transaction layer packet)?

 

Any help would be appreciated. Thanks in advance.

 

Regards,

Radhakrishna
