Description:
When trying to recieve 496 bytes (which should be the maximum allowed) an if-statement fails.

if (((isCtrlMsg == TRUE)  && ((payload->len) < (CDD_IPC_MAX_CTRL_MSG_LEN))) || ((payload->len) < (CDD_IPC_MAX_MSG_LEN)))

if the payload is of exactly 496 bytes (which is CDD_IPC_MAX_MSG_LEN) the message will not be received. The test should look like this:

((payload->len) <= (CDD_IPC_MAX_MSG_LEN))

Resolution:
if condition check such that, the message will not be received for payload of exactly 496 bytes (which is CDD_IPC_MAX_MSG_LEN)
Root Cause:
Updated the if condition to recieve the payload of exactly 496 bytes (which is CDD_IPC_MAX_MSG_LEN)
