6.11 Boot mode positions
The iMX233 can boot the operating system from different locations. The default location for the
Linux files we used is the microSD card. There are 4(four) jumpers responsible for the boot
location: D03, D02, D01 and D00. They are located on the top of the board between the processor
and 40pin GPIO connector. Note that the jumpers are SMD type and opening a jumper would
require cutting, closing a jumper would require soldering. To be able to do the quoted operations
you will need basic engineering skills and experience. You can check below the table or the
schematic for the correct positions. Value of “1” means the jumper is closed.
