1. Use the fis init command to initialize the flash image system (FIS). Optionally, you can use the -f option
to erase the contents of the flash memory; without the option, the index to the contents is overwritten.
The following example shows the procedure:
RedBoot> fis init
About to initialize [format] FLASH image system -continue (y/n)? y
*** Initialize FLASH Image System
Warning: device contents not erased, some blocks may not be usable
... Unlock from 0x50fe0000-0x51000000: .
... Erase from 0x50fe0000-0x51000000: .
... Program from 0x01fdf000-0x01fff000 at 0x50fe0000: .
... Lock from 0x50fe0000-0x51000000: .
2. Use the fis list command to show the partitions on the flash device. This initialization procedure should
give you a flash device with partitions like the following:
RedBoot> fis list
Name FLASH addr Mem addr Length Entry point
RedBoot 0xBE000000 0xBE000000 0x00050000 0x00000000
RedBoot config 0xBE3C0000 0xBE3C0000 0x00001000 0x00000000
FIS directory 0xBE3D0000 0xBE3D0000 0x00010000 0x00000000
RedBoot>
The exact memory address locations of each partition will vary from board to board.
