I am using ast2400's xdma-engine to read and write host server's memory. By using aspeed-xdma driver I can write data to host server's memory. But I have problem when reading host server's memory. After putting the read command to the command queue, the xdma-engine's status register change to bmc command not idle, down stream enging not idle. But the xdma-engine does not complete the read command neither it generate any interrupt.
How can I do?
