If there are failures (e.g., timeouts, etc.) when attempting to download files using the EBF CLI over serial, the device serial console is no longer accessible. To recover, the user must restart the ser2net from the admin interface or reboot Zombie.
Hardware Issues
SDMux doesn’t support Layerscape boards.
UHS1 and higher-speed SD Cards are not supported with SDMux hardware.
Connecting the LS1028A board to a Zombie device disrupts serial access to all connected devices due to its high power draw. Workaround is to use an externally powered USB hub between the LS1028A board and the Zombie to meet power requirements and maintain stable serial connections.
