TI Chip, 56k USDM offset/order

[rusty_lawrence]

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?

[jsa]

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.

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.

That is the first image: Not working 256k

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.
