All,hello!
I'm using mx1ads with redboot downloaded from freescale.com. May be I am supposed to consult freescale not here. But it's about the common tftp code.So if
any one could help ,I'll be very appreciate!
I can't use tftp to load file from host:
-----------------------------------------------------
RedBoot> load -r -b 0x50000 redboot.bin
Using default protocol (TFTP)
Can't load 'redboot.bin': illegal TFTP operation
-----------------------------------------------------------
I checked the source , "There is no function set" equal to "TFTP_EBADOP" defined in tftp_surppot.h. but I didn't find any function have code to set the feild 'err' of 'getc_info' with this value.
I found that the error messge is printed by the following code (in redboot_gec_init):
res = (funcs->open)(info, &getc_info.err);
if (res < 0) {
diag_printf("Can't load '%s': %s\n", info->filename, (funcs->error)(getc_info.err));
return res;
}
I didn't found any code in the tftp_stream_open function set the err with TFTP_EBADOP.
I use multiice-gdb-server and insight to debug this code , from insight ,I found that sometims funcs->open's value isn't
the address of tftp_stream_open, and it's not a fixed value.
After return from funcs->open, the getc_info.err become 4 (i.e.TFTP_EBADOP).
My toolchain is the one downloaded from ecoscentirc.com
I can load file use xmodem and http protocol.
Any ideas?
Much Thanks!
Regards

Check you have the permissions of the file correctly set on the
server. You can test this by using tftp locally on the server and make
sure it works.

This sounds like a TFTP server problem. It may be permissions
as Andrew suggested, or some TFTP servers insist that you use
the entire path name, starting with a "/" Check your TFTP
server setup.

My tftp server is CISCO tftp sever under Windows, I can access the
server from othe PC runing Windows.
Under linux ,I build a tftp server , the redboot's load function works.
I don't know why.Ok, At least , I can load file under linux.
gary:
I recall that I download the redboot from i.Mx1's summary page:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX1&nodeId=018rH3ZrDR
But yesterday I found that there is no links of redboot anymore.
I can send it to you.But it's a litte big.
There are 2 packages, totally 20 M.
My emailserver's attachment limitation is about 2M. I can make the spilt
archives, then post them to you.
Is that OK?
