We recently rolled out Wec7 OS2.3 to 100 units in the field.
Our setup has Apalis T30It connected to emcraft smart fusion SOM via microchip ksz8895 10/100 ethernet switch, all on the same PCB. That ethernet switch connects to another x86 wec7 platform over ethernet cable plus an embedded cellular modem platform, for a total of 4 networked devices on local wired LAN. We also have sdio8787 ublox ella131 wifi on the apalis platform for wireless.
Sometimes we get one of two things:
- apalis OS is unresponsive. Our app logging on two different apps stops at the same time immediately, looking like OS crash. All 3 other devices on the LAN can still ping each other. Only the Apalis module is unresponsive.
- Or, sometimes we keep logging, apps still run, but we still cant ping apalis platform, while the other 3 can talk to each other.
We’ve eliminated ethernet switch and such hardware, because the other 3 platforms still can communicate. We thought that the sdio stack patch fixed this, but perhaps not?
We will try to reproduce this with debug logs and find a way to make it happen faster. So far out of 100 units we had 10-15 crashes in a few days. The appearance is performance is worse than OS 2.1.
