There are many other registers that configure the different boot devices. For a complete description
of the booting configuration, refer to the NXP i.MX6QP Applications Processor Reference Manual
(Chapter 8: System Boot).
Internal Boot
Internal boot is the recommended boot mode for development purposes. When this boot mode is
selected, the selection and configuration of the booting process is done through the same registers
used when booting from fuses. However, this time the values of some registers are overridden using
multiple GPIOs—which are latched during power-up.
The following configuration is done internally in the ConnectCore 6 Plus module in order to enable
booting from the internal eMMC memory:
Bootstrap register bit
Corresponding GPIO
Default
configuration
BOOT_CFG1[4]
EIM_DA4
10K pull-down
BOOT_CFG1[5]
EIM_DA5
10K pull-up
BOOT_CFG1[6]
EIM_DA6
10K pull-up
BOOT_CFG1[7]
EIM_DA7
10K pull-down
BOOT_CFG2[3]
EIM_DA11
10K pull-up
BOOT_CFG2[4]
EIM_DA12
10K pull-up
BOOT_CFG2[5]
EIM_DA13
10K pull-down
BOOT_CFG2[6]
EIM_DA14
10K pull-up
By default, the system is configured to boot from MMC/eMMC (BOOT_CFG1[7:5] = 011). You can
externally change the configuration of these lines to select between different boot devices. To see a
detailed implementation of the boot configuration, check the ConnectCore 6 Plus carrier board
reference design.
CAUTION!
Make sure that EIM_EB3 (pad AA18) is not pulled high during boot. Pulling this
signal high enables an infinite loop at start of boot ROM. This feature is exclusively used
for debugging purposes.
Wireless interfaces
The ConnectCore 6 Plus system-on-module combines a wireless local area network (WLAN) and
Bluetooth dual solution to support IEEE802.11 a/b/g/n/ac WLAN standards and Bluetooth 4.2, enabling
seamless integration of WLAN/Bluetooth and Low Energy technology.
The following sections include specifications for the wireless interfaces available on the i.MX6QP
module.
