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

This link is strange for me. For 82xx, pls try: ftp://ftp.denx.de/pub/LinuxPPC/usr/src/SELF/images/ppc_82xx/ramdisk_image.gz

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 ?

Yeah, this is one possibel. The rule is that except U-Boot image and it's environment parameters location, you can program RMADISK anywhere except kernel home in FLASH.

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"

Just 't 100000 SIMPLE-PPCBOOT-ramdisk' is enough for download it to RAM.

=> cp.b

cp.b 100000 <Your-RAMDISK-Location> $(filesize)

and

=> bootm

Pls set U-Boot boot command as required before the debug. Like: =>set flash_self 'run ramargs addip; bootm $(kernel_addr) $(ramdisk_addr) =>set ramargs 'setenv bootargs console=tty0 console=ttyS0,9600 root=/dev/ram rw

Then just type: => run flash_self

Yeah, you need program linux kernel to FLASH as $(kernel_addr) in this way. Or what does mean Standalone Operation, anyway?

Best regards,

Sam
