LX2080

After the LX2080 processor operates for a period of time in a high-temperature environment, the on-board temperature sensor reads 86°C. Upon power cycling, printing freezes at the message "Fixed DDR on board", and the serial port becomes unresponsive.

Re: LX2080

Thank you for your reply. Only one board in this batch has this issue. The problem reproduces after full power cycle, but rebooting via the kernel does not trigger the fault. We are unable to run verification tools in high-temperature environments, and the board functions normally at room temperature.@June_Lu

Re: LX2080

Please validate the DDR on the high-temperature environment with QCVS DDR to confirm DDR works well.

Thanks

Re: LX2080

"on-board temperature sensor reads 86°C", is it Tj or on board sensor used to test the board temperature?

Thanks
