Hello,

I'm using the 56371 DSP and I have to boot it with serial EEPROM in
I2C-Mode. The Procedure is described in the manual, but I do not know
how to make a boot image from the *.cld file.
I managed to make a .s file using srec.exe and then I converted that to
intel hex format. Now, I don't know how to put the information about
start adresses and record length at the file header. Does anyone know a
tool (or methode), which can do that?

Thanks for any help in advance!

you can make a .lod (use cldlod utility) where the data structure will
be easily seen in text format.
Another way is to use emulator: you have to load program into DSP563xx
internal RAM and then copy it into EEPROM by a small utility written for
that DSP.
It is not complicated - belive me ! :-)

where may I get such a utility?

you have to write it oneself. It depends on EEPROM type you used.
Ooops ! New, DSP56371 BootROM loads X: and Y: RAM also.
Thats great !

"(...)
Assuming the EEPROM address starts at 0: -
EEPROM Byte expected at DSP Example
Address
0 PstartAddress2 00
1 PstartAddress1 04
2 PstartAddress0 00
3 XstartAddress2 00
4 XstartAddress1 05
5 XstartAddress0 00
6 YstartAddress2 00
7 YstartAddress1 06
8 YstartAddress0 00
9 PdataLength2 67
10 PdataLength1 45
11 PdataLength0 00
12 XdataLength2 21
13 XdataLength1 35
14 XdataLength0 43
15 YdataLength2 56
16 YdataLength1 64
17 YdataLength0 24
18 data in P, X and Y order -
19 must make up whole 24 bit words
-
-
-
- PstartAddress2 00
- PstartAddress1 04
- PstartAddress0 00
(final word is start address of rogram to run)
The above example would store: $004567 words from P:$400
$433521 words from X:$500
$246456 words from Y:$600
And will start running from P:$400 once all of the data has been downloaded.
(...)"
----------------

So, you must write a simple routine which will write to EEPROM a block
of data (size of block may depend on EEEPROM organisation), and then
call it three times for your P:, X: and Y: data, after writing 18 bytes
of header first, of course.

I did it for DSP56362, but for emulated on SPI interface on GPIO pins,
so its useless for you.

Good luck !

Hello Roman,
you have to insert an extra Byte in front of "0 PstartAddress2 00" to get it
running. The bootcode from freescale is wrong.
