[U-Boot-Users] DULG/Manual: 7.6. Standalone Operation with Ramdisk Image

On PQ2FADS-VR board the U-Boot is programmed into flash sector started at address 0xFFF00000 (and ending at 0xFFF3FFFF I presume). The next sector on the flash (starting at 0xFFF40000 and ending at 0xFFF7FFFF ) is used for U-Boot environment variables.
Does it mean that a minimal ramdisk image ramdisk_image.zip "for first tests" for 82xx, which I have downloaded from:
ftp://ftp.denx.de/pub/LinuxPPC/usr/src/SIMPLE-PPCBOOT-ramdisk
could be programmed directly onto flash (bypassing putting it into ram first and then copying it into flash) using CodeWarrior/WireTap CCS's "Flash Programmer" tool into next 8 sectors, starting from address 0xFFF80000 ?
Aternatively - if I am to strictly follow steps outlined in DULG/Manual: 7.6. "Standalone Operation with Ramdisk Image" I am not clear on addresses used there ?
My "normal" (without ramdisk) booting sequence is: => tftpboot 200000 uimage => bootm 200000
So what addresses I should use in:
=> tftp "/tftpboot/SIMPLE-PPCBOOT-ramdisk"
and
=> cp.b
and
=> bootm
steps ?
Thanks, Best regards, Alex

Some flash address after the end of kernel image should be fine. Later invoke bootm with: bootm <kernel-address> <ramdisk-address>

Please confirm that you downloaded a file from this link. It was rmoed a long, long time ago and should NOT point to any valid data any more.
If you have this file, then remove it. Don't even attempt to use it on a MPC82xx system. It was never meant for this.
The DULG section you quote correctly lists:
"Ramdisk images for tests can be found in the ftp://ftp.denx.de/pub/LinuxPPC/usr/src/SELF/images/ directories."
so please use these instead.
Best regards,
