i'm not following this. I just ordered a TI chip and programmer to try on my marine ecu. How do I convert/pad a 56k bin file to work on the TI?

Add 136kB of 0xff in front of your 56kB bin and add 64kB to the back. You will end up with a 256kB bin. Your original 56kB will be at file address 0x22000-0x22fff.
Code: Select all
EEC ROM Bank Hex editor File Address
0 0x02000-0x0ffff
1 0x12000-0x1ffff
8 0x22000-0x2ffff
9 0x32000-0x3ffff
You want your 56k bin at the file address the EEC expects for Bank 8. The TP chip is a multibank chip so it wants all the banks in the file. It will serve the default bank 8 to an 8061 EEC.
Go to the TI website and download any of their 8061 bins, open it in a hex editor to see the layout as an example.

Thank you! I’ll give this a try!

This is driving me nuts!
Not sure what I'm doing wrong.
Burn2, TI J3, have padded bin 0189 order, 256k file.
Can someone give me some guidance?
I purchased these TI J3s a while ago, cannot get a single byte of data written to them.
Not working 256k
- Not working 256k
Working, small amount of memory, 0xFF written:
- Working
Bank 0 and 1 working
- Bank 0 working

Try 00000 - 3FFFF

FWIW I had to convert the D9S binary to 40000 bin size and subtract 20000 on offset for it to work right.

My bin is 256k, which is 0x40000. 0xFF everything but 0x22000->0x2FFFF.
Subtract offset in BURN2 Moates PROM I/O?

You can try that. I did it to my XDF for it to work.

NEVERMIND...
Just checked my D9S, 40000, 22000 offset NOT SUBTRACTED.
