Multiple environment storage devices
  • After using usb commands in U-Boot, Linux might fail to detect USB devices.
Workaround: Reset the module before booting Linux. This can be done using the reset button (SW2) or the U-Boot command reset.
  • While using CM-T3730, with on-board micro SD card, on the CB-T3 baseboard or the SB-T35 baseboard, with alternate boot selected, the boot process will default to the CM-T3730 primary storage (micro SD card), but U-Boot will still expect to find the environment in the external NAND flash.
Workaround: Use the env device command to switch to the primary CM-T3730 storage:
> env device mmc import
  • While using CM-T3730, with on-board NAND flash, on 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-T3730 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-T3730 storage:
> env device nand import
