Jetson模组上电后启动失败且无打印

当前64GB Jetson Orin模组在自研域控主板上无法正常上电启动,模组表现为:
模组SYS_VIN_HV上电14.8V,SYS_VIN_MV上电5V,两路供电电源设计电流均满足10A以上供电要求且当前测量纹波远小于2%,VCC_RTC上电3.3V(备用电池RTC供电);

目前Orin模组上电启动时序配置如下:
POWER_BTN_N默认拉高,SYS_VIN_HV和SYS_VIN_MV正常上电100mS后拉高MODULE_POWER_ON,再过100mS后再拉高SYS_RESET_N;

目前Orin模组状态测量如下:
各外部电源(包括SYS_VIN_HV、SYS_VIN_MV、VCC_RTC和SYS_VIN_SV),而且模组CARRIER_POWER_ON输出为高,但是串口UART3 TX和RX脚均一直为低电平(测量已经排除无短路到GND的问题,信号直接从测试点悬空测量,信号对外部无连接)

为了避免其他可能设计问题,当前模组在官方套装上能正常进入系统并运行,而且已经测量Orin模组上电后增加功耗为5W左右,Orin模组连接器焊接没有问题、串口UART3 TX和RX脚与测试点连接良好,Orin模组J62管脚通过0R电阻连接到GND,Orin模组G60和H59上拉至1.8V电阻均已经NC;

针对上述Orin模组上电后串口没有打印的相关问题,暂只能判定模组启动失败,恳请帮忙分析可能原因及上述上电时序有哪些需要调整,非常感谢!

Please compare your full power sequence to that of devkit as listed in Design Guide. And for other possbile issue, please first check your schematic design based on the schematic checklist sheet attached in the Design Guide doc.

非常感谢,调整增加POWER_BTN_N配置后,模组已经启动且打印正常,但是当前运行一直卡在UEFI配置过程中且等待半个小时均无法进入;
相关打印截图如下:

We would suggest using debug UEFI binary to check where it gets stuck.
Please refer to Build without docker for details.
Please open another topic to discuss for UEFI issue.
