[ECOS] upload program in NEC V850 RAM

[ECOS] upload program in NEC V850 RAM

[Teresa Fazio]

Hi,  
I'm new in this mailing list and I found someone of you having problems in uploading   
programs in NEC V850 RAM, like me.   
When I try to load a simple program Hello.S3, I do  

RedBoot>load   

Ctrl a + s  
choice ymodem and then the file Hello.S3.  
But the answer is:  

CCCCCCCCCCCCCCCC*** Warning! Attempt to load S-record to address: 0xffffffff  
RedBoot does not believe this is in RAM  
Use TFTP for a chance to override this.  
*** Warning! Checksum failure - Addr: ffffffff, EF <> 00  
xyzModem - CRC mode, 647(SOH)/4(STX)/5(CAN) packets, 316 retries  

What is the problem?  
Thanks in advance.

The addresses in your s-record file indicate it should be loaded to 
0xffffffff, which isn't right. Check your s-record file, and how it was 
built, and particularly how the memory map was linked.

Or more relevantly, if it isn't an s-record file, either convert it to one 
or choose the appropriate flag to "load" to tell redboot what format it is!

oK, it could be so, 
but why the code is loaded and executed if we try to load it by the 
v850-elf-gdb?

Thank you for any help

If this is the *very same* file that you load into v850-elf-gdb, then that 
may well show I'm right :-). GDB accepts ELF format file, but I could well 
believe ELF load support is disabled in the v850 redboot to save space.

You can try converting the file to an srec file using "v850-elf-objcopy -O 
srec infile outfile.srec". If Hello.S3 really is an srec file you should 
be able to just open it in a text editor or "more" and it should look 
something like:
S010000076383530666C6173682E6865785B
S1180000070A400F4CF0010A400F64F08F07F4FF8F07F2FF008D
S11800150000000000000000000000BC0700000000000000000F
S118002A000000000000BC0700000000000000000000000000FA

although obviously the actual numbers vary.
