[ECOS] How to load redboot_ROM in to flash

[ECOS] How to load redboot_ROM in to flash

[Prabhat Shrivastav]

Dear All

I have PCI card for downloading the file (.elf or .srec) in to the ram.
I am able to download the redboot_RAM.elf in to ram and able to get redboot prompt on to serial console.
Now I want to load the redboot_rom in to flash and next boot is from flash .
Any idea how can I download redboot_rom.elf in to flash from the redboot running from RAM  .
Thanks in advance

With regards
Prabhat Shrivastav

The message indicates that the CPU is getting a memory access
exception. Is there really memory at this address? RedBoot's idea of
the address range may be wrong. Is the memory controller set up
properly? Is there a memory management unit that may be
interfering? You will have to investigate the specific hardware and
system setup to work out what is actually happening.

I don't know enough about this platform or the SH3 to suggest anything
else.

You can use mfill to work out the address at which it starts to
fail. This may give you a clue as to how much memory you actually
have.

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?

Do you also "send" the file from your host system (in minicom for example 
Ctrl-A S)? Have a look into the manpage of xymodem.

Hi  All

Is anybody had used "load " command with 
xymodem on redboot .
I  had used like this 
RedBoot> load -r -b 0x8c080000 -m xmodem
but its not working.
Please suggest me to overcome with this problem.
I am stuck hear since my target dosen't have ethernet connectivity and 
my PCI card doesn't supporting the flash which we had used.

You need to use the -r option to load raw binaries.

[ECOS] How to load redboot_ROM in to flash

[Prabhat Shrivastav]

Dear All

I have PCI card for downloading the file (.elf or .srec) in to the ram.
I am able to download the redboot_RAM.elf in to ram and able to get redboot prompt on to serial console.
Now I want to load the redboot_rom in to flash and next boot is from flash .
Any idea how can I download redboot_rom.elf in to flash from the redboot running from RAM  .
Thanks in advance



The PCI card and its GUI is not supporting the flash which we used .
But ecos is supporting .
So I want to use RAM redboot to load ROM redboot in to flash.
May I on right track ,Please guide to overcome from this.
where I have to modified the things.
