MSS#45

Bootup failure during the serial flash busy state

Revision(s) Affected:

AWR1843 ES1.0

Description:

If the radar device is rebooted internally or externally while the serial flash is busy completing a previous operation, like erase, format etc, the radar device might fail to bootup since the serial flash would not respond to the commands from the bootloader during the bootup process.

Workaround(s):

The user application should make sure if its triggering an internal reset due to watch dog expiry or other reasons, it should reset the serial flash to bring it to a known state or wait for completion of any pending issued commands to serial flash before it resets the AWR device.
