sdefisher Posted September 26, 2022 Share Posted September 26, 2022 (edited) I have been trying to troubleshoot an odd ethernet issue. It's been narrowed down to the CPU board proper. I have 3 CPU cards, only one has good ethernet performance. This board has a revision number 604045-106. The boards that are not working well are 604045-107. We use GPASCII and SENDGETSENDS with the ethernet communction. And they are not pushing data though at the same rates with the new boards. Is there any configuration on these that would affect them? I have all 3 boards running the same firmware (22.214.171.124), and same project downloaded by the same version of the IDE (in-case the complier is differnt. As far as I can tell all boards are also running the same backend linux kernel version as well (3.2.21-powerpmac-smp). All of the CPUs were acquired as part of a full UMAC system at various dates/times in the last few years. Update: The boards that don't work were setup with IDE version 126.96.36.199 and the working one was done with 188.8.131.52. Re-downloaded my project via 184.108.40.206 into the good board and now that CPU no longer performing well. The symptom seems to stem from GPASCII not transmitting the ACK character. Which is was previously doing without fail. Would 220.127.116.11 have anything to do with this? By default it's should be on, I don't see how the PowerPMAC Ide would change this. Is there a GPASCII switch to force the ACK to be active? I know there is one to turn it off. Edited September 26, 2022 by sdefisher Quote Link to comment Share on other sites More sharing options...
