Two 6655 DSP through srio interface communication, the host to send data from the machine, the first-CodePudding

Homemade two 6655 evm entry, the host through SRIO cycle to send data from the machine, send the first set of data displayed when sending success completion code=0, from the machine on the corresponding memory of received data and to trigger the doorbell interrupted, but the second and later send data are the completion code=1, didn't receive data from the machine,
Host:
SRIO_path_configuration xlanea 1
X1080a200 SWRITE x10802200 from 0 to 0, 312 bytes, the completion code=0
SRIO_path_configuration xlanea 1
X1080a200 SWRITE x10802200 from 0 to 0, 312 bytes, the completion code=1
SRIO_path_configuration xlanea 1
X1080a200 SWRITE x10802200 from 0 to 0, 312 bytes, the completion code=1
SRIO_path_configuration xlanea 1
X1080a200 SWRITE x10802200 from 0 to 0, 312 bytes, the completion code=1
SRIO_path_configuration xlanea 1
X1080a200 SWRITE x10802200 from 0 to 0, 312 bytes, the completion code=1

From machine:
SRIO_path_configuration xlanea 1
Received doorbell which are SWRITE operation done.
