Re: RevPi Connect missing modules after image update

Re: RevPi Connect missing modules after image update

Thanks. From the kernel log I can see that there is a communication problem (crc error). Which firmware and hardware revison do the modules have (numbers left of the IO connector or scan the dcm with for example your mobile)?

Re: RevPi Connect missing modules after image update

Hi,

Could you please provide more details?

Image version
Running kernel version
Kernel log / dmesg

With this we can hopefully find together a first clue.

Re: CAN driver broken on revpi

Hi

Has the Con CAN overlay been enabled? There should be a line in /boot/config.txt of `dtoverlay=revpi-con-can` or check with `revpi-config status revpi-con-can`.

Enable overlay: revpi-config enable revpi-con-can
Disable overlay: revpi-config disable revpi-con-can

Hi

Has the correct overlay been loaded (dtoverlay=revpi-compact in /boot/config.txt)? Are there any errors in dmesg respective /var/log/kern.log?

Re: MIO Inputs either 0 or 10700 with 2-10v sensors (Converted)

Yes, the other inputs are not affected by readings from one sensor. Could you please sketch your schematic / wiring so we can get a better understanding of your setup? Thanks!
