Voipac i.MX53 SODIMM PC - Development kit is delivered with E-Fuses set to boot from NAND interface by default.

Modules support multiple booting options:

  • NAND Flash
  • microSD/MMC
  • SPI Flash
  • I2C EEPROM


The procedure described below is intended for special purposes when upon costumer request E-Fuses have been left unprogrammed.

BE AWARE THAT E-FUSES PROGRAMMING IS NON REVERSAL PROCESS! WARRANTY CLAIM CAUSED BY IMPROPER E-FUSES PROGRAMMING WILL NOT BE ACCEPTED!

Programming E-Fuses

Before programming E-Fuses, E-Fuse supply gate must be enabled:

barebox:/ md 0x53fd4064+4
