Hello,
My name is Hyewoon Jang.
I am currently trying to test the RD33772C14VEVM board, and I have set up my environment as follows:
Software:
MBDT for BMS 1.2.0 + MBDT for S32K3xx 1.4.3
(I installed version 1.4.0 first and then applied the 1.4.3 patch.)
Model:
MBDT for BMS → BMS_Examples → rd33772c14vevm → rd33772c14vevm_s32ct → rd33772c14vevm_s32ct.mdl
Hardware:
The hardware is connected as shown in the attached photo.
For now, I have not connected a battery, since I would like to check the basic operation of the model first. I am only supplying 12 V power to the board.
After setting up the environment as described above, I tried to download the model to the board, but the download process shows “Could not connect to target.”
Therefore, I imported the generated code into S32 Design Studio 3.5 and tried to download it from there. In S32DS, the build process completes successfully.
Therefore, I connected the board to Vector CANalyzer in order to check whether any CAN messages are being transmitted from the board. However, no CAN messages are displayed in CANalyzer.
Since I suspected that the issue might be related to the J-Link debugger, I also tried connecting the board using TRACE32. However, the reset indicator repeatedly turns red, and TRACE32 shows the error message “target power fail.”
At this point, I simply want to verify whether the board is operating properly by checking if any CAN messages are transmitted.
I really would like to resolve this issue.
If there are any items that I should check, I would greatly appreciate it if you could let me know. I will follow your guidance and try each step.
Could you please advise me on what I should do to solve this problem?
#rd33772c14vevm, #CAN, #s32k344, #JTAG, #MBDT
Hello,
First of all, I am sorry for the late reply.
From the message you sent, I suspect that the board is not properly powered. I see that you built the application in S32DS too, but the build process to do not involve to deploy the application to the board. You have to create a Debug Configuration compatible for S32K344 and deploy the .elf from there.
Since you didn't connect a battery yet, I recommend you to power the board from cell emulator instead of the beefy screws found on the EVB. I am not sure that you can power up the board using the Shunt resistor (R62), please thoroughly check the schematic.
In the readme for the model, it states that you can power up the board from the emulator board:
Connect the power supply to the emulator board: 12V -> BH1(K30_12V_L) and GND -> BH2(GND_KL31_DOWN)
Let me know if this solves your problem.
Best regards,
