Dear FLEX-5000 customers, Last weekend there were a number of reports of RX1 and RX2 initialization problems with the new firmware v1.2.2.0 that we commented on this past Monday. The good news is that these problems helped us to identify and to the best of our knowledge resolve a number of intermittent and configuration dependant issues. One example is that occasionally a radio might not return to receive after transmitting until PTT was pressed again. In our lab, it required 56 hours of automated PTT execution at a 4 Hz rate to generate a single failure.
Today, we posted on the website the new FLEX-5000 Firmware v1.2.2.3 release that resolves the receiver initialization and other intermittent I2C control based problems. I2C is a two wire communications protocol for low to moderate speed control functions. Technically, the only change we made was to convert from polling to interrupt driven I2C control in the firmware. The polling method created infrequent I2C buffer overruns that could cause intermittent failures. All customers who have tested the new firmware to date report that it has resolved their issues. Thanks to those of you who helped us test the improved firmware. We encourage everyone to perform the upgrade. Also, K5SDR will be QRV part of the day tomorrow for the FlexRadio QSO party. I hope to have the chance for a QSO with many of you then. 73, Gerald Gerald Youngblood, K5SDR President FlexRadio Systems 13091 Pond Springs Rd. #250 Austin, TX 78729 Phone: 512-535-4713 _______________________________________________ FlexRadio Systems Mailing List [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
