Content-Type: text/plain; charset=us-ascii Sender: owner-linuxppc-embedded@lists.linuxppc.org List-Id: Hi, I'm working on a MPC860T. I've been trying to receive from a peripheral via IDMA and it seems to work OK, but when I study data received from IDMA I can see that there are some bytes at the end of each IDMA buffer received that are wrong, in fact they haven't been written to the buffer and previous bytes remain; but interrupts are received Ok, and the number of read bytes in the peripheral are the IDMA set. It could be an access problem to the peripheral with IDMA(without IDMA this access is totally OK!). Does anybody have any experience in this regard? Thank you in advance. --------------------------------------------- Pedro Parrilla Jimena Prodys.S.L Embedded Systems Programming Trigo,54 e-mail pparrilla@prodys.net Leganes(Madrid) 28914 Tel.:+34916896880 http://www.prodys.net ** Sent via the linuxppc-embedded mail list.
