Jetson orin nano core board PMIC burned

我们在给jetson orin nano 8GB 烧录固件过程中遇到了核心板电源芯片烧毁的故障。
我们使用购买的Jetson nano orin devkit 以及配套提供的电源适配器给 8GB OrinNano烧录固件。
操作流程是:先断开AC电源,将核心板插入核心载板,然后短接Recovery,最后通电。
在操作过程上电过程中偶发核心板电源芯片烧毁(总共烧录60个,核心板烧毁4PCS),附件是故障图片以及所用电源和载板。



我们量测核心板电源芯片周围滤波电容,发现滤波电容两端电阻值只有几十欧姆,几乎短路。请问这是正常现象吗?

Please reach out to the ecosystem partner / vendor from where you purchased this devkit.

能否提供损坏器件型号用于修复,供应商回复,没有图纸且人为损坏,无法提供支持。

We do not provide the schematics or repair services for the Jetson Orin Nano module. You will need to find out what caused the failure/damage like overvoltage supplied, not followed the recommended guidelines/procedures.
