Flash Division of Trizeps

Trizeps I to V

The Trizeps modules ( Trizeps I to Trizeps V) use one NOR-flash as main non-volatile memory.
This memory contains the bootloader, boot-pictures, the OS and in case of Windows CE a reserved space for flashdisk and persistant registry.

The default flash-divisions are listed below. These will be used when using epsm,ereg,eflashb0.

x16: one flash (16bit bus-width).
x32: two flashes (32bit bus-width).

Trizeps VI

The Trizeps VI module uses one NAND-flash as main non-volatile memory.
This memory contains the bootloader, boot-pictures, the OS and in case of Windows CE a reserved space for flashdisk and persistant registry. Unlike previous Trizeps-modules, the flash-memory-division is not fixed.

Name Notes
Bootloader Block 0..6
MBR Master-Boot-Record describing the flash-layout
Boot-Partition This is a FAT formated region to store autoboot-scripts, boot-pictures and nk.nb0-RAM-images. This region is used, when you enter mount nanddisk within the bootloader
XIP The xip-partition is reserved for xip.bin OS-images. Its minimum size is 6 blocks and may be used for other things, if a RAM-image (nk.nb0) is used; see: Handling Powerfail (Trizeps VI)
User-Partition User-Store. Similiar to the flashdisk on previous Trizeps-modules
