 Gateworks boards with eMMC FLASH may have a variety of eMMC parts that differ slightly in block size of the boot0/boot1, rpmb, and user partitions. The minimum hardware partition sizes you should count on for Gateworks products are:
-||= eMMC =||= BOOT0/BOOT1 =||= RPMB =||= User Sectors =||= User Size =||= Notes =||
-|| 8GB  || 4MB || 128KB || 14876672  || 7264MB  || Newport standard ||

+ 1. The enhanced user size calculation is based on using the entire user hardware partition as enhanced which Gateworks can configure via our test fixture for Gateworks specials and customs. This number is based off a 33% reduction in the original user size appropriate for TLC flash types but in some cases you may have boards with MLC flash types offering a 50% reduction instead. 
 
 Note in some cases manufacturers may allow you to adjust the Boot and RPMB partition size with a one-time vendor command.
