=== BOOTMODE pin ===
*'''BOOTMODE''' is used to setup a boot priority sequence. BOOTMODE = is equal to #SYS_BOOT4 and it . It has a 100K PU signal.
More resources available at [{{#lst:Template:Links|IGEP_COM_AQUILA_ISEE_Hardware}} IGEP COM AQUILA Hardware Reference Manual] section 6.1 and [{{#lst:Template:Links|IGEP_AQUILA_EXPANSION_ISEE_Hardware}} IGEP AQUILA EXPANSION Hardware Reference Manual] section 5.8.
=== BOOTMODE design notes ===
* It is very useful place recommendable add a jumper header series with a 100 Ohms resistor in your base board to control system manage boot modepriority sequence. For example: If you want to reflash the internal NAND memory from microSD card you will need to insert a unmount the jumper to avoid to flash the NAND firstly.
