CL-SOM-AM57x: Linux: Known Issues

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. The image can be downloaded from the Linux firmware git repository: https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/plain/ti-connectivity/wl18xx-fw-4.bin

mini PCIe 0

The mini PCIe connector is disabled by default in the SB-SOM-AM57x board. Workaround : Use the following U-Boot command to pull PCIe 0 out of reset: i2c dev 4; pca953x output 1 1
