No EEPROM detected #25

Open ebpace opened 6 years ago

Hi Kris, I'm launching the EM7180_MPU9250_BMP280.ino and get this : capture39 and nothing after that I'm guessing I don't have the configuration file loaded onto the EEPROM. Do you know (if that's indeed the problem) why it's not there and how can I retrieve it? (I'm using the Tindie Ultimate Sensor Fusion Solution) Thanks

Yes, it looks like there is no EEPROM on you board. Where did you get the board? Can you tell if the EEPROM is damaged. Perhaps send me a picture and I can tell.

If you bought it from Tindie then the firmware was loaded onto the EEPROM and the device was verified to function before shipping out. Is it possible that in soldering the board the EEPROM was damaged? This is a common problem.

Yes, the board is from Tindie. How can I tell if it's damaged? img_20180524_093012 img_20180524_092200 I had the same error when I was prototyping without the soldering tho...

Hard to tell in these pictures but if the EEPROM has any chips, typically at the corners, it is likely dead. One way to tell, use the master I2C bus pins at the top right of the board and scan for I2C devices. You should see 0x68 for the MPU9250, 0x76 for the BMP280, and 0x50, 0x58 for the EEPROM.

It is possible you are not entering pass through mode properly for some reason.

Yea I don't have the 0x58 it's probably dead, thanks a lot for your help!

capture43

kriswiner commented 6 years ago

You shouldn't have 0x60 either, this is likely a corrupted EEPROM.

Did you test it before soldering? Always recommended.

I can offer you a discount on buying a replacement. Order one new one from Tindie and I will send you two. Make sure to put this offer in the comments of the order form.
