Ethernet
  • eth0 name is assigned to the secondary Ethernet adapter which port is routed to auxiliary P10 connector of SB-SOM-AM57x.
Workaround : Make sure to use eth1 name for the primary Ethernet port (P21) and eth0 for secondary (P10).
RTC
  • The RTC device can start with invalid information.

Systemd getting stuck during start-up with continues printing:

systemd[1]: Time has been changed

The problem is caused by incompatibility between 32 bit Linux and systemd regarding the size of time_t. The problem is discussed in systemd issue 1143: https://github.com/systemd/systemd/issues/1143

Workaround : disable system time from RTC on start-up.
WiFi
* Wifi firmware revision 8.9.0.0.48 can cause to the CPU core to get stuck.
Workaround : upgrade the firmware file /lib/firmware/ti-connectivity/wl18xx-fw-4.bin to revision 8.9.0.1.55.
