Why?  What's wrong with using a script?

It's pretty messy to call such functions directly.  You'd have to supply
a valid argc/argv list which corresponds to the arguments you need.

Again, why?

n.b. vague/unresponsive answers will most likely be ignored.

Your question is a bit vague.  Are you asking how to execute a set of
commands
automatically when RedBoot comes up?  If so, look at startup scripts.

It looks like your FLASH doesn't read 32 bit quantities properly.
Unless your FLASH driver sets 'CYGSEM_IO_FLASH_READ_INDIRECT', RedBoot
will read the FLASH (FIS directory, FCONFIG data, etc) directly from
the FLASH, using the most expedient means possible.  On most platforms,
this will be using normal 'memcpy()'.  Depending on how your device
and system are configured, this will possibly go through a data cache
which may also be causing problems.

Did you notice that Redboot says this:

Use 'fconfig -i' to [re]initialize database

What happens when you do this?

You may also want to try

fis init

If you're using "-r" I take it you are sending the binary file, right? :-)

NB, the "-v" shouldn't have any effect with -m xmodem.

Try sending a .srec (and drop the -r). If that works, but binary (.bin) 
files with "-r" still don't, then let us know as that may indicate a 
problem with raw loads.

I guess you start with reading the documentation. Have a look at e.g.:
http://sources.redhat.com/ecos/docs-latest/redboot/x86pc.html
http://sources.redhat.com/ecos/boards/pcmobo.html

But RedBoot for Synthetic Linux target doesn't make sense for me. Why would you need a boot strapper?

Well, this may indicate that it did hit the breakpoint, but has failed for
some other reason. Does it do the same thing when you don't set
breakpoints?

Also try enabling remote protocol debugging in GDB using "set remotedebug
1" (or in newer versions, "set debug remote 1").

The $T string means that the target is reporting a signal and trying to
inform GDB - probably the breakpoint you hit. But if it's coming out the
serial port, whereas if GDB is connected over ethernet you won't see it.

I found that I was having the same problems as the ones discussed in this
post:
http://sources.redhat.com/ml/ecos-discuss/2001-04/msg00006.html

After getting past that, I am now finding that my code loads over the

information, such as "Network stack using..." then I get a message:

[New thread 1]

The board then seems to hang for a little while and then the program stops.
I have breakpoints at cyg_start and cyg_user_start, however, neither of
these get hit by the debugger.  The target disconnects from the debugger as
well.

Any help?

Thanks.

RE: [ECOS] RedBoot

I have rebuilt ecos using the default configuration for the MBX template.  I
rebuilt my application using the new ecos build.  I then downloaded the code
and set a breakpoint at cyg_start().  I am still seeing the board hang when
I run the code.  On the RedBoot serial port I get a $T... string GDB output
message.  I can hit return when I am on the terminal connected to the serial
port and I get the same $T string GDB message.  I'm really confused as to
why this is hanging.

Hold on, stubrom.c? It sounds like you're trying to run a GDB stub rom
image under RedBoot? All I was talking about was setting a breakpoint at
some point _after_ system initialization time.

You should have just got a clean build tree and rebuilt from scratch in the
default configuration. Just try that in the first instance and make sure
that works. Unless you know that does already work, in which case we'd want
to know what you've changed!

Are you talking about setting it in stubrom.c or in vectors.S?  Is there a 
way to view the assembly source files?  When I start Insight and load my 
.img file, I am only able to browse .c and .cxx files.  Do I need to use the 
console to set the breakpoint in the .S file?

I have set a breakpoint in my cyg_user_start() routine and found that it 
never got to that point.  I was getting the unreadable output that I 
mentioned before after the "Network stack using 65536 bytes for misc space" 
message.  And then the board just seemed to be hung.

Thanks.

Setting a breakpoint much further in the initialization, like cyg_start.

I initially single-stepped through the first for loop and the board hung.
Then I read the very detailed comment before which explicitly says not to do
this.  So I re-ran the application and stepped over it and it still hung the
board.  I tried to set a breakpoint at the next function call after
hal_if_init(), and the board still hangs before hitting the breakpoint.

Is there something I should look at or try?

When I compile my application, the output is an mbx.img and mbx.srec file.
I guess the confusion is that I was not referring to any RedBoot files,
rather my
application files.

So, I guess I would open my mbx.img file and run it.

The fact you are mentioning those extensions seems to indicate confusion -
those extensions are only likely to be relevant for RedBoot itself but you
say RedBoot's already on your board, so you don't have to do anything with
any other RedBoot files.

Any applications you've built in ecos will be in ELF format and can be
downloaded just by selecting it with File->Open, setting a breakpoint if
you like, probably opening the console window with View->Console to see any
output, and then hitting the Run button which should both download and run
your program.

I am trying to download code using GDB/Insight with my MBX860 target running

Do I use the .img file or .srec file?

Doesn't really matter since they switch places in the address map

The reason the _documentation_ contains directions for the socketed

redboot is the only thing running on my board when this occurs.  It just
seems that when a lot of information is exchanged with the Windows NT telnet
application, this error occurs.  The only way out is a hard reboot.  I
haven't done much investigation as to where this error is generated from.

Is this _with_ the timer patch I provided?

Surely this is with eCos, not RedBoot (since RedBoot does not use MBUFs).
Can you duplicate it?  provide a failing case or scenario?

RE: [ECOS] RedBoot

[Anthony Massa]

I am able to get it to start downloading the file now.

I'm getting a checksum failure at 8c840 though.

And I also run out of mbufs, do you know what the cause for this is?

Are you sure that you are running a TFTP server (and not FTP)?

RE: [ECOS] RedBoot

[Anthony Massa]

I was able to change the MAC address (using fconfig).  I am able to do ping
from Win NT host and get back packets.  I cannot run using BOOTP, I must use
a static IP address.

However, I still am not able to run the telnet application and connect to
the MBX board.  Do you know what is the problem there?

Do I need to run a BOOTP server from my host?

Should I try a tftp server application?

RE: [ECOS] RedBoot

[Gary Thomas]

[-- Attachment #1: Type: text/plain, Size: 6268 bytes --]

As I expected, the problem is that RedBoot/eCos can't get at the NVRAM
information.  This is because the NVRAM is connected via the I2C interface
and that is broken on the MBX!  I've not been able to figure out how to
make it work reliably.

However, the attached patch should let you get by.  It adds some additional 
information kept by RedBoot.  Basically, run 'fconfig' and enter the ESA 
(MAC) address manually.  Then RedBoot and eCos programs will be able to set 
up the interface properly.

Let me know if this works/helps/...  If so, I'll apply it permanently.

Try this patch and let me know what the output is.  This will print some
additional information at the point where the driver is trying to find the
address information.

RE: [ECOS] RedBoot

[Gary Thomas]

The problem seems to be that the driver in RedBoot (eCos) can't get at the
ESA for your board.  It is supposed to do this by accessing some NVRAM on
the board and then digging it out of a data structure kept by EPPCbug.  If
eCos can't find the address, it falls back to a hard coded one which is
  0x08 0x00 0x3E 0x28 0x79 0xB8

Did you build this RedBoot?  Can you?  If so, perhaps we can debug the 
NVRAM code and figure out why it works for me but not for you.

This is the ESA, but not the correct one for your board.  This is why the
BOOTP setup does not work.

RE: [ECOS] Redboot

[Doug Fraser]

Hello Anthony,

One thing I would try, is convert the srec to pure binary.
Then use plh to load it into RAM at a known location.
To do this, run 'env' first, and set the load address.
For example, set it to 10000 hex.

then, assuming that you have set up your ip (niot),
and that the binary image is in /tmp/redboot.bin,

plh 20 0 /tmp/redboot.bin

You will now have the image in RAM at 10000 hex.
The length will be reported from plh when it completes.
(it reports in decimal) Assuming that it is 20000 hex bytes long,

pflash 10000 30000 fc000000

That should do it. Then power off, switch J4 to select the block
you just programmed, and power up.

(I am assuming a general knowledge of MBX and EPPC-Bug here)

Perhaps Bill Gatliff can add some details off line.
He is also working with an MBX board, and has dealt with
much of this already. Bill????

cheers

Doug

[ECOS] Redboot

[Anthony Massa]

I am trying to get redboot running on my MBX board.  I have built the
redboot images.  However, the srec image I noticed started at address
0xfe000000.  I could not download this image using eppc-bug.  So, I used
objcopy with the line from the documentation:

powerpc-eabi-objcopy -O srec --change-address=0x02040000 redboot.img
redboot_mbx.srec.

I then tried to download this new image (redboot_mbx.srec).  I cannot see
any output from the serial port or any response from the board.

Can you help me out and let me know what I might be forgetting to do.

Thanks.

Currently only Ymodem (or Xmodem with CRC) is implemented.

What platform did you try this on?
What problems did you encounter?

It's pretty hard to help much if all you give us is "it did
not work so well."

[ECOS] redboot

[Jörg Rapka]

Dear ecos developer

I'm very interested in the redboot of ecos.
I have downloaded the latest version from CVS.
In the sources I found the information, that
not only download by TFTP but also xyzmodem
will be supported (the documentation only
references TFTP). I compiled the sources
and tried download by xyzmodem, but it did
not work so well.
What is the status of this implementation?
What was your terminal application and protocol
used during development tests?

Best regards, Joerg
