J784S4XEVM: 开发板出现故障,无法工作。

Part Number: J784S4XEVM


上电之后,指示灯就亮,散热器不工作,开关不好使,拨动开关指示灯没有变化,如图所示,怎么解决?

  • 请看一下电源是否满足手册上的要求。
    2.1 Power Input

    A power supply is not included with the EVM and must be purchased separately.

    External Power Supply or Power Accessory Requirements:

    • Output Voltage: 24-48 VDC

    • Output Power Capacity: 100-160 W (depending on use case and connected peripherals)

    • Efficiency Level V

    Note

    TI recommends using and external power supply or power accessory which complies with the applicable regional safety standards such as (by example) UL, CSA, VDA, CCC, PSE, etc.

    拨动开关指示灯没有变化

    是Power Control [SW1] with LED for Status [LD7][LD8][LD9]这几个指示灯吗?

  • 电源满足要求,是PWR LED   FAULT LED   LD7  LD8  LD9  LD10这几个指示灯
