Simulink Generated Code Not Executing on DEVKIT-MPC5744P RevE

Hi All,

I have spent about 12 solid hours trying to figure this issue out. My issue is:

Code generated using MBDT 3.2.0 does not execute on DEVKIT-MPC5744P REV E board.

Here is a list of facts/conditions:

If I load an example LED hello world project in S32DS, build and flash, everything works without an issue.
Using Simulink 2020b Update 7 (I suspected this was my main issue since 2020a is latest compatible with MBDT 3.2.0).
- I am unable to install 2020a due to severe hard-drive limits on my workstation
I tried the hot fixes for MBDT 3x, which caused the toolbox to fail (lots of errors and broken links), so had to reinstall MBDT 3.2.0 without hot-fixes
I am using the RBF file from MBDT 3.2's tools/bootloader folder
- I also tried the RBF file from hot-fixes, no change to issue
I tried two versions of S32DS (2.1, 2.1 with updates, reinstalled several times, 2017R). Using 2.1 with updates using online updater.
Jumper settings:
- I have J31 un-populated, J39 un-populated, J30 connected 1-2, all others are as recommended
- I tried J30 unpopulated with J39 populated, J31 un-populated to match another employee post, that didn't change anything. Schematic suggests that switches PWM to analog for Ardunio compatibility

Summary of steps carried out:

I flashed the DEVKIT with the RevE RBF file needed to be able to flash via Simulink.
- If I failed to do this, then RBF would get stuck at init (so at least I know this was somewhat working).
I loaded gpio_mpc457x which makes the blue LED toggle by default, upon pressing SW1, light goes green, SW2 results in red light
- I also tried the hello world UART model, no luck, figured the LED example is easier since I don't have to keep trying to terminal in
I tried to generate code from Simulink, when prompted, I pressed reset then released and let Simulink call the flasher, RAppID BL Progress shows Erasing, then completes flash (100%) and closes itself.
I reset the board and I don't see any LED changes. Application doesn't seem to be executing.

Import the project from Simulink (the one generated above) into S32DS using the procedure posted on this board with the following "fixes":
- Rename .S to .s extension of any files in the new project directory
- Change project settings to reselect the E200Z4 with re-selection of libraries with support.
- I then was able to build successfully (with warnings, no errors).
I then attempted to flash the generated ELF and same issue, the program did not execute.

I am suspecting there is something wrong with my board. Or it could also be a Simulink version issue. Can someone please advise?

Sorry for lengthy post. Thank you in advance for your help.

When I was posting this question, three similar topics came up, they are unresolved but seem to suggest a hardware issue.

Here is what the sticker on the back of my board says:

SCH-29333
REV E1
700-29333
REV A

Another couple stickers read:

TDA7081
MT19361609

The MCU itself has the following stamped on it:

SPC5744PFMLQ9
1N15P
QMZDN1911T

I happen to have one more DEVKIT MPC5744P RevE I can try. I am hesitant since they are expensive (used to be around 35 USD, now over 125 USD). I will post back with results.

So the second, possibly newer board worked!

I plugged in my spare board.
I flashed the OpenSDA RBF RevE file needed to flash via Simulink
Using Simulink 2020b Update 7, I generated and built code (COM port properly updated under build settings), placed board in BAM mode using reset switch
After flash completed, program executes (blue light blinks, I tried SW1, SW2 and lights changed)
Jumper settings are the same as other board.

Here are the relevant details of the board that worked on my first attempt:

SCH-29333
REV E1
700-29333
REV A

Another sticker:

TDA7081
MT19361762

MCU Stamping:

SPC5744PFMLQ9
1N15P
QMZFA1922H

Is my other board defective or damaged? Are there any options to get it repaired?

It works fine when building hand code from S32DS so I am struggling to understand how it is a hardware issue. Thank you.
