Hi! I am writing a driver for the on-chip Ethernet controller (Exactly Similar to TC35815) on TX4938. I am facing one problem for a long time. I am getting the following two interrupts but not the transmit interrupt when I attempt to transmit. 1. Non-recoverable Abort. 2. Master Abort Reception. I have just created one transmit descriptor and attached a small data buffer to it. Through the MAC loop back I want to test this basic transmission. I am not getting the TxComp interrupt. I am giving the physical address of the descriptor to the DMA controller and assigning the physical address of the data buffer into the DataBuff field in the descriptor. Is it possible to get the transmit and receive interrupts in the MAC loopback condition. Could anyone please tell me what can be the reason of these interrupts (1. Non-recoverable Abort, 2. Master Abort Reception) and how can I overcome it.
