I’m experiencing issues powering up my Orin Dev Kit. Despite applying power via both USB-C and the DC barrel connector, the LEDs remain dark (notably, I’ve successfully powered an identical dev kit using the same power sources).
I’ve started investigating the power management ICs and have found that the LM9036MX output is oscillating between 0 and 3.3V, while the TPS53015’s SW terminal is reaching up to 5V. Additionally, I’ve noticed a periodic chirping sound emanating from the board, which suggests a short circuit induced by power management logic.
I’d greatly appreciate some guidance on debugging this issue, as an RMA would take too long to resolve.
Yes, I’ve previously booted this AGX Orin devkit and flashed it with JP6 DP without any issues. It’s also been used by several colleagues in the past.
I haven’t checked the serial console output yet, as I suspected the problem lies with power delivery. I don’t suppose I can have access to the devkit’s PCB layout files that I could use for further hardware troubleshooting?
Unfortunately, I’m in the dark on this one. As far as I know, the board went through functional testing (USB com, I2C com, etc.), but I’m still stumped as to the cause - clearly, there’s an underlying issue, but I haven’t been able to pinpoint it.
My hope is that the problem is something simple, like a faulty IC that can be replaced, assuming the SoC is still intact. If the SoC is damaged, we’ll likely need to go the RMA route.
My current plan is to troubleshoot the power delivery chain, referencing the NVIDIA Jetson AGX Orin Developer Kit Carrier Board documentation (SP-10900-001_v1.1, page 41):
Seems some component are damaged/failed. If you have some hardware related knowledge, you can try to locate issue components based on the schematic and PCB file of devkit carrier board P3737_A05 in DLC. If you don’t have such knowledge, you can try RMA for this devkit.
