The MOD_TEMP_SHDN_EN_N strap is pin J62 of the 699-pin connector and labeled as GND_009 on the connector symbol. It must be grounded for all Jetson AGX Orin modules, including AGX Orin Industrial.
2、“The A25 does not correspond to the board design revision number. 180-13737-DAAF-A25 is still the P3737-A05 carrier board.”-----But according to our A05 schematic, a single GPIO controls the power-up of both HV and MV on the hardware side. Actual tests on our purchased A25 carrier board show HV lags MV by roughly 20 ms. The physical board does not match the schematic, so we are confused about this issue.
3、Latest test update: A Linux host was connected via USB cable to the Type‑C interface of our custom board. The custom board entered recovery mode, allowing us to install the OS onto the core module on the custom board from the Linux host. After installation, the core module could not boot on our custom board. Once we pulled out the core module and fitted it to the official A25 carrier board, it booted successfully into the system.
What can we learn from this test? Can we confirm power supply and timing are okay? The module still fails to boot and load OS on our custom board. Please advise detailed troubleshooting steps for the next round of testing. Thanks!
3、最新测试进展:我们用一台 linux 主机,通过 USB 线连接到我们自制板卡的 type-C 接口,自制板卡进入 recovery 模式,然后通过 linux 主机可以给插在自制板卡上的核心模块安装系统,安装完成后,核心模块在自制板卡上面还是无法启动,把核心模块拔下来,安装到官方的 A25 载板上,可以正常启动并进入系统。
这一步能说明什么问题吗,是否能说明电源和时序是 OK 的?在自制板卡上还是没办法启动和进入系统,我下一步该如何排查,麻烦给出具体建议,谢谢!
