LP-MSPM0G3507: SYSCFG_DL_init()

Hi,

What version of the SDK you are using with? Have you tried with the latest SDK version 1.20.01.06?

Best regards,

Cash Hao

Ya I was trying with that only.

Hi,

Can you take a picture of your LP? I have tested on my LP, without stuck in the while loop. 

Best regards,

Cash Hao

HI,

I see your board is Rev 1.0. It is an older version for early sample board. The HFXT is different now on the newest EVM board. For your board, I would suggest you to change the CANCLK source to SYSPLLCLK1 which is sourcing from SYSOSC. 

Best regards,

Cash Hao

Oh ok, thank you so much.

can you please tell me, how to check it is older version board?

Hi,

It is marked on the board. 

Best regards,

Cash Hao

Ok, thank you so much.

I tried CAN loop back code it worked, using SYSPLLCLK1.

But when I'm trying just transmitting the data using the CAN, mcan single message tx, I'm not getting anything in P-CAN or in logic analyzer.

One more thing I selected PA12 and PA13 as tx and rx. But both pins are showing low in logic analyzer.

Can you please help me in the same?

Hi, 

Have you connect the PA12/13 to a CAN transceiver first? 

Best regards,

Cash Hao

No, without it we can't monitor it with P-Can?

Hi,

Yes, without a transceiver could cause your issues. 

Best regards,

Cash Hao

Oh, ok ok,

Thanks a lot for the information.

I connected the CAN transceiver as well. 

But still I'm not able to get data in PCAN.

Please help me with this.

Hi,

Happy new year!

Could you send out your project here? I can find one Rev 1.0 board and test with it. 

Best regards,

Cash Hao

Hi, wishing you a happy new year.

Right now, I'm just testing the CAN tx. 

By example code only (single or multiple msg tx).

The example code is for CANFD, I change the configuration for classic CAN.

Hi,

I am testing with mcan_multi_message_tx_tcan114x_LP_MSPM0G3507_nortos_ticlang and also changing it to classic CAN. 500kbits.Desired Sampling Point 87.5%.

My hardware shows below. MSPM0G LP + CAN transceiver board + CAN analyser. 

I am using a logic analyzer on the PA26 and PA27 to capture the signal. 

I can get the CAN message without any issues.

Best regards,

Cash Hao

Hi, this board you are using is Rev 1.0??

Hi,

No, I am using Rev A for test.

Best regards,

Cash Hao

Hi,

Ya, that's why it might be working for you.

I'm having the Rev 1.0.

can you please share the SYSCFG screenshots as well.

Hi,

I directly send you the sysconfig file here. mcan_multi_message_tx_tcan114x.syscfg

Best regards,

Cash Hao

Thanks a lot.

one more thing, is there any way this CAN part can be use in REV1.0 board?

Hi,

I am not sure whether the Rev 1.0 EVM board can work with the latest SDK version. Let me find one board and test with it. 

Best regards,

Cash Hao

Update one information,

Setting the following configuration in the sysconfig. Enable loopback mode->"enabled and external". It can observe the TX message without using a transceiver with this configuration. 

Best regards,

Cash Hao

Ok, 

Thanks a lot Cash Hao, 

I really appreciate your efforts.

Thanks for helping me out. 

Ok, 

Thank you so much.

Please let know about the Rev1.0 board as well.

Ok ok.
Thanks a lot Cash Hao, for clearing all the doubts.

I really appreciate your efforts.

I'll defiantly want to connect with you, If possible please accept my request, and if you are on LinkedIn please connect.

Thank you so much.  

Hi, can you please tell me the part no of the transceiver you are using here.

And one more thing.

Here I'm getting Error after CRC.

Is it correct, or something need to be changed?

I am using TCAN1145 for test. https://www.ti.com/product/TCAN1145-Q1

Best regards,

Cash Hao

What is the test environment when you getting this error? 

Best regards,

Cash Hao 

I was using classic CAN, 500 kbps Arbitration Rate, 87.5 sampling point, 2 Mbps data bit rate. In single msg tx example code 

ok thank you so much.

Hi,

I tested on the LP and did not connect other nodes on the CAN bus. 

There is a NAK in the end of the frame. So, I think the error is getting from the receive nodes in your side. 

Best regards,

Cash Hao

we are not connecting anything on Rx side.

We are just observing the Tx signals from PA12.

in our application we are enabling the UART and CAN as well. 

Can you please share the config file for the same (500 Kbps abstraction rate and Classic CAN configuration).

Thanks and Regards

Attached the test code.

MSPM0_BMS_New_V1.1.zip

Hi,

I tried your code, but I still not get the errors.

Best regards,

Cash Hao

Anything you updated in our code ?

I only change in here.

OK, i just need to transmit data, so I didn't enable loop back.

but now it is working for basic data, 0x01, 0xFD and all, but when I'm transmitting the Cellvoltage parameter for Tx, it is not sending. 

can you please help me out in this.

Thanks and Regards

Hi,

The txMsg.data[0] data format should be uint8_t. Like below.

txMsg.data[0] = 0x00;
txMsg.data[1] = 0x01;
txMsg.data[2] = 0x02;
txMsg.data[3] = 0x03;

Best regards,

Cash Hao

If we want to transmit more than 8 bits then can we use uint16_t or uint32_t ?

Hi,

If you want to send a 16bit data, you then need to separate the data into two 8bit format. You can try with below method.

 txMsg.data[0] = (uint16_t data)>>8;
txMsg.data[1] = (uint8_t) (uint16_t data);

Best regards,

Cash Hao
