I have read above topic, my AGX get the same issue, core A never bootup, and aurix terminal shows :
ERROR: SftyMon_IoHwAbs: Thermal Alert Triggered
INFO: SftyMon_IoHwAbs: Board Thermal Alert = HIGH
INFO: SftyMon_IoHwAbs: Board Thermal Shutdown = HIGH
INFO: SftyMon_IoHwAbs: Xavier A Thermal Alert = LOW
INFO: SftyMon_IoHwAbs: Xavier A Thermal Shutdown = HIGH
INFO: SftyMon_IoHwAbs: Xavier B Thermal Alert = HIGH
INFO: SftyMon_IoHwAbs: Xavier B Thermal Shutdown = HIGH
I think that due to Thermal detect device error. It’s a hardware error, not a software one. So i want to know is there a command can disable Thermal device?

Dear @Tom.Zheng,
There is no command to disable to Thermal device. Could you check reflashing (Reflash 99% , the sdkmange stucks) to see if core A can be flashed/booted.

Also, May I know when did you notice this issue? Is the board used in car or office desk?

Thanks for your reponse!
Yes, first time i try to flash core a, it stop at 99.67%, and i wait a really long time, then i stop flash, after i read above link, and an other topic, i flash core a after switch power adapter button, then i flash successed.
Last week it can be started, but have to try several times, last Friday, it can not run, and terminal showed that message.
In car.

Dear @Tom.Zheng,
Does that mean you could flash the target with Thermal Alert Triggered and notice the issue occuring again after couple of days?

Hi SivaRamaKrishnaNV,
Yes，i can flash the target, there is a gap between poweron and Thermal Alert. Not couple of days, it’s no help flashing core A, turn on power switch again a few second, Thermal Alert shows up. So i don’t think it’s a software problem.

Hi SivaRamaKrishna,
Is there any answer for this problem? Or can you show me the position of Thermal device on the Pegasus module board?

Dear @Tom.Zheng ,
We only noticed that reflashing fixed the issue for couple of customers. It seems you are getting the issue frequently.

can you show me the position of Thermal device on the Pegasus module board?

May I know why you need it. Accordingly, I need to check with team.
