Subject: Re: [ECOS] How to load redboot_ROM in to flash
Date: Tue, 31 Aug 2004 14:01:00 -0000 [thread overview]
Message-ID: <s134cdd5.005@EMAIL> (raw)
Dear Nick
Thanks for your valuable suggestion.
This is my redboot banner.
RedBoot(tm) bootstrap and debug environment [RAM]
Non-certified release, version v2_0 - built 13:12:33, Aug 27 2004
Platform: SE77X9 (SH 7729)
Copyright (C) 2000, 2001, 2002, Red Hat, Inc.
RAM: 0x8c020000-0x8e000000, [0x8c047278-0x8dfd1000] available
FLASH: 0x80000000 - 0x80400000, 32 blocks of 0x00020000 bytes each.
RedBoot>
And my redboot_RAM is reside at 0x8c020000 SIZE : 0x20000 ,so I had selected the RAM
address 0x8c080000 for redboot_ROM.bin .But as you said ,I had tested with mfill command
at 0x8c080000, its failed.
It gives message : ** command abort - illegal memory access?
I am unable to get this why this memory has blocked . May this is blocked or reserved for
some other purpose.
One more thing: Even though if try to load the redoot_ROM.bin file to 0x8c047278 or
%[FREEMEMELO] with "load -r -b 0x8c047278 -m xmodem" command I an unable to load
into RAM .But if I use mfill at 0x8c047278 I able to fill the memory.
Please suggest me to solve this
Thanx in advance
Regards
Prabhat Shrivastav

Are you sure that the memory at 0x8c080000 is RAM? Can you set it from
the RedBoot prompt using the mfill command? The number of C's seems
suspicious, you should be able to start sending the file quicker than
that. The loaded range is also suspicious, it looks like you have
loaded -1 bytes. Does the binary file actually contain anything?
