37
The ARTIK 530 Module supports a variety of booting scenarios as depicted in
Table 33. Table 34 describes the values of the PAD signals needed to initiate the various booting scenarios. When nothing is
done default booting will take place. (AP_GPB13_SD0_BOOT is High, AP_GPB15_SD1_BOOT is Low and
AP_GPB4_VID1_3_BOOT is High) In this case the ARTIK 530 Module will try to boot from eMMc, if this fails it will continue to
initiate a boot from SD0 and if this fails it will continue booting from the USB device. The other booting options perform in a
similar manner. Changing the PAD signals according to the values in Table 34 will allow for different booting options to be
executed.
