New Contributorwe are using in our board the device CYCLONE 5 - 5CSEBA5U23,
when we are trying to power up the device in temperature under zero( -5 cel),
we are getting the " altera_load" failed with error code -2" and the "conf_done" stays low.
If the board is power up in a positive temperature , and we are cooling the board, the device working fine.
We check all signals control , the are setting ok.
Super ContributorHi,
Have you follow our userguide when configuring and power up the FPGA?

New ContributorHi Aiman,
We designed our board according to Intel's recommendation.
The device works great in all temperatures, but when we trying to turn it on at temperatures below zero
we are getting the " altera_load" failed with error code -2".
Is there anything we can try to resolve this ?
Super ContributorHi,
Thank you for the update. Can you provide us the screenshot of the failure/error code?
Regards,
Aiman
Super ContributorAlso, please provide the full device OPN.
Super ContributorHi,
If you ae using commercial device, the operating junction temperature should be between 0 to 85C.
New ContributorHi,
1. I have attached a screenshot of the error code.
2. what do you mean when you wrote "full devic OPN"?
3.We use CYCLONE V - 5CSEBA5U23I7N, the operating junction temperature should be between -40 to 100C.
Super ContributorHi,
-How many devices show the same failure when power up using below 0cel?
-Please share the top marking for the failing devices.
Regards,
Aiman
New ContributorHi Aiman,
- We tested 10 devices and 8 of them showed an failure when power up below 0cel.
-You want me to share the top marking of the CYCLONE V - 5CSEBA5U23?
New ContributorHi Aiman,
Is there any update?
New ContributorHi Aiman,
See attached top marking of the CYCLONE V - 5CSEBA5U23.
