Linux, MPC555 and serial .s19 download...

[mcdowell]

Sorry about the lack of detail...  The board is a PB-0555 from Axiom 
Manufacturing.  All I have to gone on for the ROM monitor is the following 
from the board manual (available from 
http://www.axman.com/files/MPC5XX/PB-555/doc/Manuals/PB555man.pdf):

______________________________________________________
You can also load a program into memory and execute it using this utility. A 
simple "hello world"
program is provided for you on the disk as an example. Follow these steps:

1. Select 1 on the main menu. At the monitor prompt > type dl and hit <enter>.

2. Select the send text file (or upload) command from your terminal program 
and locate the file
named "HELLO_R.S19" included on the software disk. Send this file to the 
board.

3. If your terminal is set to Echo characters sent, you should see each line 
of the file sent. The
last line of the file contains the START address of the hello program, which 
is 3FA004.

4. Type go 3FA004 at the prompt. You should see the phrase "Hello World!" 
echoed back to
the screen, which is all that this simple test program does, each time you hit 
a key.

5. To exit from this test program, hit the RESET button on the board.

Another excerpt from the manual:
________________________________________________________
The utility software provided uses the serial port connected to your PC 
running a terminal
program as described under "Getting Started". While you can use almost any 
commercial or free
serial communications terminal interface, it is important that you configure 
it to work properly with
this board. The following settings are important:

1. BPS: 9600, Data Bits 8, Parity none, Stop Bits 1
2. Flow Control should be set to HARDWARE
3. Emulation should be ANSI
4. When uploading files to the board, be sure to send in Text mode.
5. When programming CMFI memory, you must use ONE of the following:
    a. 15 millisecond pace delay after each line
    b. wait for echo character following each line

This is all the information I can provide.  So it is expecting text mode 
transfer.  It seems as though ascii-xfr is sending more than just the plain 
.s19 file that the monitor is not expecting.  I can communicate with the board 
and issue commands, the download just doesn't work.

Thanks for the interest.  Any ideas are welcome.
