The Industrial Raspberry Pi Forum

Hello,
I am having the below format (attached as well)
AIO|MIO|DIO|Connect+SE (16GB)
and I am receiving the below error:

Jan 20 11:34:15 RevPi84278 kernel: piControl: recv len from pibridge err(got:0, exp:20)
Jan 20 11:34:15 RevPi84278 kernel: piControl: talk with mio for dio data error(addr:30, ret:-70)


Nothing is wired in I/O and I have energized only DIO's module output

I changed the bridge connectors, just in case one of them was faulty. In the first place I received an error between MIO|DIO, I swapped bridges and then I received an error in AIO|MIO then I took off completely the connector between AIO|MIO and replaced it with a new one, then I took an error again in MIO|DIO.

Please advise

Thanks in advance

Hi, could you send us a SOS-Report via SUP-5688?

Thanks I will!

Hi I have made a test setup and can give you the following feedback
- check your PiCtory configuration and swap the modules accordingly
- change the RevPi Connect to RevPi Connect SE
The (cryptic) error from the kern.log means that piControl tries to communicate with the wrong module

Thanks for the reply.

So I just need to change the revpi edition to Connect SE, in address 0 and reload revpi?
I changed it!
I keep getting the same error
I am attaching the pictory config as well

Hello mpandos,
thank you for the SOS Report you provided via E-Mail. I have seen the errors in kern.log again. Well then I see that "piTest -d" outputs no error - OK: Here the module configuration deviates from the one of your image.

Can you please do a fresh PiCtory configuation and pick the modules according to the hardware configuration?

Thank you & BR

Thats my setup now, after updating each module one by one following your guide (https://revolutionpi.com/tutorials/imag ... re-update/)

Here is my pictory setup.
I keep getting the same mistake

I finally changed all the modules. I followed the updated procedure and everything worked like a charm. So I guess there are some issues with the 1st set of modules.

Hello again,

The problem is not solved after all. Tell me what kind of info you need in order to make a step-by-step debugging!

thanks

Hello mpandos,
good that you have more modules available and therefore the cause is on the hardware level. Unfortunately, there is no way around an RMA.
I will clarify the further steps with you in the support ticket.
