hi @icty
在XADC高于90℃时会断电,这个限制可以取消吗?
默认一般是125C自动shutdown。关闭的方法如下。
By default, the automatic shutdown feature is disabled for designs that do not use XADC.
If XADC is instantiated, the automatic shutdown feature can be disabled either by setting
the OT signal within Config Reg 1 (41h) High, or by adding the following constraint to the
project XDC file:
set_property BITSTREAM.CONFIG.OVERTEMPPOWERDOWN DISABLE [current_design]
谢谢

Hi @icty,
这里是90C是指的是电源管理芯片吗?可以通过PMBUS去设置。电压建议不要超过DS191的table 1上的要求。
Thanks

Hi @icty,
你看看这里有一个温度报警控制的视频:

Hi @icty
这里的90度是否是电源管理芯片的,电源管理芯片的配置也是通过TI的工具配置。XADC里也可以配置OT,默认是125C,请参考ug480:

@icty那可以确认一下ug480里的OT Upper Alarm的值,可以修改高一点,再试。
