3.3 Known Issues (xWR1642 ES1.0 and xWR6843 ES1.0 Devices)

The ROM bootloader in XWR1642 pre-production devices is not compatible with SFLASH variants that support extended addressing mode. In particular, the Number of Address length field of the SFDP command response being non-zero is not supported. The total SFLASH addressable region in XWR1642 devices is 8 MBytes. Thus, Number of Address length = 0 (corresponding to 3 bytes address length) satisfies the addressable range. However, the compatibility issue is with variants that allow for 3 or 4 bytes address length.

This incompatibility is addressed in the production version of the XWR1642 silicon.
