Troubleshooting the NORwegian Teensy Clip Edition

Poor Clip Contact

  • Unknown Chip Errors
  • Dumps not matching up in WAY-launchers
  • Getting lots of errors when you verify them in BwE or PS3DumpChecker
  • Errors when you try to verify after writing the NOR/NAND
  • Incredibly slow read/write speeds

Most of the problems from using clips is from the clips not making a good connection with the NOR or NAND.

Especially when using the clips made for NORs with NANDs, you need to make sure that the the top pins on the clips are making contact with the top pins on the NAND.

Poor clip connections will cause most of the problems with reading/writing to the NOR/NAND, as well as the majority of errors that you get when you check your dumps. So try these steps first and then repeatedly reseating the clips before moving on to the other sections.

Things you can try

  • Make sure the clip is the right way, dot on clip matched up to dot on NOR/NAND
  • Clean the legs on the NOR/NAND with isopropyl alcohol
  • Use a needle or some other small pointy thing to push the pins on the clip further out, obviously be careful it’s easy to mess up the pins
  • Trim the sides of the clips if they’re hitting any components next to the NOR/NAND
  • Reseat the cables
  • Make sure you’re applying even pressure to the clip
  • Make sure that you’re setup is stable, you don’t want things moving around while you’re trying to flash/dump

Power Problems

  • Unknown Chip Errors
  • Dumps not matching up in WAY-launchers
  • Getting lots of errors when you verify them in BwE or PS3DumpChecker
  • Errors when you try to verify after writing the NOR/NAND
  • Incredibly slow read/write speeds
  • Teensy Not Being Recognized
  • High Pitch Whine

After the clips having poor connections the next thing is power problems. With the Clip Edition I’ve mitigated this quite a bit. The clip edition is capable of providing enough stable power that their shouldn’t be an issue. But that doesn’t mean there still can’t be a problem.

Power problems can cause most of the same issues as bad clip connections, just the bad clip connections are more likely.

If your Clip Edition has a high pitch whine, unplug both USB cables. There is a short between 3.3v and GND on the board. You can confirm this by checking for continuity using a multimeter between GND and 3.3v. Make sure the NAND/NOR switch isn’t stuck somewhere between the two. Check if there are any debris stuck in between pins on the board, or around any capacitors.

Things you can try

  • If you’re using an external power supply it might be too noisy, I recommend powering the NORwegian Teensy Clip Edition over microUSB.
  • Check for 3.3v at the external power headers while the microUSB cable is plugged in. If you’re not getting 3.2v to 3.4v there might be a problem with the onboard regulator, or the USB charger you’re using.
  • Check if you’re getting 5v from the USB charger. Use a multimeter and check between ‘GND’ and this side of the capacitor ‘CIN’. You can use the outside of the USB port as ‘GND’, or any other ‘GND’ point on the board.
