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?

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.
