21 The resulting kernel image should be available in linux/arch/arm/boot/zImage.
27 A couple of bootloaders able to boot Linux on Assabet are available:
51 Brief examples on how to boot Linux with RedBoot are shown below.  But first
52 you need to have RedBoot installed in your flash memory.  A known to work
75 To initialize the flash directory::
85 Writing a kernel image into flash
97 To write it to flash::
105 The kernel still requires a filesystem to boot.  A ramdisk image can be loaded
113 Now the kernel can be retrieved from flash like this::
117 or loaded as described previously.  To boot the kernel::
121 The ramdisk image could be stored into flash as well, but there are better
122 solutions for on-flash filesystems as mentioned below.
129 convenient way to store a writable filesystem into flash.  JFFS2 is used in
130 conjunction with the MTD layer which is responsible for low-level flash
147 Now we must know the size of the unallocated flash::
157 the type of flash.  See their usage below as an example and take care of
162 	size of unallocated flash:	0x503c0000 - 0x500e0000 = 0x2e0000
166 the remaining flash space as well.  To write it::
174 what they are in the boot process.  From Redboot, the 'fis list' command
187 	SA1100 flash: probing 32-bit flash bus
188 	SA1100 flash: Found 2 x16 devices at 0x0 in 32-bit mode

199 Therefore to boot Linux with the kernel and its root filesystem in flash, we
206 You might want to boot with a root filesystem over NFS, etc.  It is also
207 possible, and sometimes more convenient, to flash a filesystem directly from
209 many tools to deal with flash memory as well, to erase it for example.  JFFS2
218 time the Assabet is rebooted.  Therefore it's possible to automate the boot
221 For example, I use this to boot Linux with both the kernel and the ramdisk
225 	Run script at boot: false true
235 	Network debug at boot time: false
