Multiple environment storage devices

Workaround: Reset the module before booting Linux. This can be done using the power button or the U-Boot command reset.

While using the CB-T3 baseboard or the SB-T35 baseboard, with alternate boot selected, and the MMC card is not present in the socket, the boot process will default to the CM-T3530 primary storage (NAND flash), but U-Boot will still expect to find the environment in the MMC card.

Workaround: Use the env device command to switch to the primary CM-T3530 storage:

> env device nand import

-* After switching the environment storage device using {{parameter|env device}} command, U-Boot might print an incorrect message when saving the environment, reporting the destination storage device as the original boot storage device.
+* After using usb commands in U-Boot, Linux might fail to detect USB devices.
-: This can be ignored; the environment will be saved to the correct storage device (as reported by the {{parameter|env device}} command).
