Question regarding OAD Demo Tool

Other Parts Discussed in Thread: REMOTI

Hi,

currently I am working on a little program which is basically doing the same as OAD Demo Tool. I got a successful enable response from the RC but I never got the new image running. I think it was never copied to the active image area. With the demo tool I got the same image running.


So i observed with Remoti Packet Sniffer what the demo tool was doing different than mine and I recognized that in the 4th data frame sent by demo tool the data payload did not match with given bin file.


concrete example: basic remote controller image

binary file (at 0x00C0):                               00 00 00 00 FF FF FF FF FF FF FF FF 34 12 F8 F8 96 F0 33 25 00....

frame sent by demo tool:  (10 02 03 00 30 00)  00 B0 00 00 FF FF FF FF FF FF FF FF 34 12 F8 F8 96 F0 33 25 00....

 

Why does demo tool change the second data byte to 0xB0? And are there any other data which are sent unlike the data in binary file? Is the source code of the demo tool maybe available somewhere?

 

thank you very much,

Andreas

    Andreas,

    the image size in bytes needs to be stored at offset 0xC0 (little-endian wise, 4 bytes). That's the only intervention host does wrt plain binary

    Please also note you need to retrieve the image ID (offset 0xD0) and compute the CRC of the whole image in the subsequent Enable request command.

    We can give you the OAD server tool installer but you would have to contact officially a TI sales rep or a Field application engineer/factory apps.

    Hope this helps you.

    Thanks and have a nice day
