Pironman 5 won't boot if nvme pip is connected

Took known working pi 5, put into pironman5 case. Would not boot, led stayed solid red. Checked and reflashed bootloader to make sure, no change. Saw another forum post where it was recommended that someone disconnect one thing at a time to see what was keeping it from booting, so i did that.

Positively confirmed that the nvme pip is what’s causing the problem. When it IS connected, i get the fail to boot. If i just disconnect the cable, the pi boots up just fine. The LED’s on the nvme pip never light up whether it’s connected or not.

  1. It is recommended to replace the FPC cable and see how it works.
  2. Use a multimeter to measure whether the FPC cable is short-circuited. (As shown in the picture)
  3. Please verify according to the tutorial FAQ solution:
    FAQ — SunFounder Pironman 5 documentation
  4. It is recommended to provide us with a video of the problem.

Forgot to mention i already tried replacing the cable. For more context, i am not attempting to boot FROM the nvme drive. i am booting from SD, and using nvme for data storage. I am running home assistant OS, which is marked as compatible in the documentation.

I followed the steps in the link you provided, and jumping the force enable pins did make the power led light up. I double checked the FPC cable condition, verified continuity with an ohmmeter, and re-assembled the pip just in case.

The nvme drive is confirmed working via a nvme to usb dock attached to my laptop.

It is recommended that you provide us with the problem video so that we can help you analyze and solve the problem.
If the video memory is too large, it is recommended that you upload the recorded video to onedrive and share the video link with us to give us access to the link.

  1. Please carefully check whether all the assembly parts are assembled correctly. Please watch our assembly video to confirm.

  2. You remove PI5 from the chassis and use the power supply to power PI5 alone. Can it work normally?
  3. Then you assemble each component one by one and start PI5 to see if PI5 can work normally.
    That is, after you assemble a module, start PI5 first. If it can start, it proves that the component is normal and will not cause PI5 to fail to start. Then assemble the next component and start it again, and so on, until the pironman5 assembly is completed. If PI5 cannot start after assembling a certain component, please tell us.

As stated in my previous posts, i’ve already done all of these things except for taking a video.

At this point, a video would just amount to me showing that the pi boots fine without the nvme pip connected, and fails to boot immediately if the nvme pip IS connected.

We will send you a replacement NVMe PIP module and FPC cable to see if this resolves the issue. Additionally, we recommend using the official PI5 power adapter to supply power to the chassis for optimal performance.
