Does anyone have a Trace32 .cmm script for TC377TP device ?

I found some examples from the Trace32 documentaiton, but not sure which one's to use.

Any thoughts ?

What should the script to do? CPU selection is always possible via CPU -> System Settings...

I want to use the .cmm script to flash the .elf file. It can be done manually, however I want a .cmm script for automating some of my activities

If you look in the directory where you installed T32 as in my case "C:\T32\demo\tricore\flash" you will find the file tc37x.cmm which will flash your elf file to the internal memory of the TC37x.

Well... TC37x instead of TC27x, but you could just modify the TC39x scripts, and cut memory from 16 MB to 6 MB.

I tried the tc37x.cmm and it gives me exception

system.reset
system.detect.cpu
system.attach
DO tc37x.cmm CPU=TC377TP PREPAREONLY DUALPORT=1
data.load "MYHexFile.hex" --- CPU generates an exception on this command
data.load.elf " MYelfFile.elf" /NOCODE.

Any thoughts ?

Hi

How did u generate the elf/hex file?
are u using the AURIX development studio?
or BIFACES with example codes?

bus error might be related to wrong memory mapping of code to program flash?
i suggest u contact Lauterbach support for more efficient support -> support@lauterbach.com

I am using HiTech Development Studio toolchain for generation of elf and hex files. Yes, I contacted Lauterbach support to get more support.

memory mapping of code to program flash? - With regards to this, due to think the tc37x.cmm is doing this wrong memory mapping ?
Because when i flash the hex file manually it works without any error.

Guys,

I contacted Lauterbach and got a Interim Update of Trace32 SW (Released on 20-Oct-2020), they also recommend to use flash script from "T32\demo\tricore\hardware\triboard-tc3x7\tc377tp\demo_flash.cmm" script
This script works for me now.
