in reply to: FlexCase G Inconsistent Connection #19385

Thank you for reaching out.

I understand that it is a bit difficult to connect to the flexcase at the moment. But if you ever get the chance, I would like to collect a few more pieces of information before proceeding:

• Has this behaviour been consistent since the first time your booted up the flexcase or did it just start happening
• Did you make any kernel-level changes to the flexcase? Can you provide the output of the command uname -a and the contents of the file /boot/extlinux/extlinux.conf?
• Based on your infrastructure, will the unit be assigned an IPv4 or IPv6 address

I will try to rule out any software related issues before I start looking at any hardware faults that might have happened during shipping.

Thanks,
Omar

Hi Brian,

Your screenshot shows a very interesting behavior, the data seems to be drifting which might indicate a protocol mismatch in the MPU-MCU communication.

The first thing I always recommend is implementing some sort of data-checking logic to validate incoming messages. But in your case, I would make sure that the number of bytes per transfer is the same on both sides.

I can try to help you further if you could provide a stripped down version of the Simulink model that is causing these issues.
