IOC_01

Limited number of DIOs available for the bootloader backdoor

Revisions Affected:

Revision E and earlier

Details:

The highest possible DIO number that can be used for the bootloader backdoor is limited to the number of available GPIOs minus 1. The bootloader backdoor pin is configured through SET_CCFG_BL_CONFIG_BL_PIN_NUMBER in ccfg.c. That means that if the device has x GPIOs, the highest DIO number that can be selected for the bootloader backdoor is DIOx-1, even if higher DIO numbers are available for the device.

Workarounds:

There are no workaround for this issue.
