Connecting to S32R274 with Ubuntu host laptop using a USB C to Etherent converter.

[HaMun]

Hello,

I am trying to connect an NXP board (S32R274) to my Ubuntu laptop in order to execute some code on the S32R274 board using S32 Design Studio. I am using a USB-C to Ethernet converter to connect to the board via the Ethernet port. I can ping the NXP board, and the Ethernet connection is recognized by the host laptop. However, when I attempt to debug an S32 project and execute it on the board, I receive the following error:

Error in final launch sequence Failed to execute MI command: -target-select remote fe80::24bb:4778:e687:da56%enxa0cec8abc033:10000 Error message from debugger back end: could not connect: Network is unreachable. could not connect: Network is unreachable.

In my debug configurations, I have selected Generic TCP/IP as the JTAG device under GDB hardware debugging, and then entered the IPv6 address of the NXP board as the IP address.

I am wondering if this type of connection is even possible, as the NXP documentation mentions that the PEmicro Multilink Universal JTAG debugger should be used to deploy the code. It should also be noted that the project I am trying to execute is an S32DS application project, which includes a forever loop for two cores.

I would appreciate your help!

Best,

Hadi

Hello,

Hmm, which exact evaluation board you are referring to?

Did you program any SW into it?

To me it looks like there is no SW on the board programmed.

Hello,

Thanks for your reply!

The development kit is S32R274RRUEVB. https://www.nxp.com/docs/en/user-guide/S32R274-S32R372-QSG.pdf 

Yes, I tried to run a simple S32Ds application project using S32 Design Studio tool. For example, you see a code for one the core in the following:

/*
* main implementation: use this 'C' sample to create your own application
*
*/

#include "derivative.h" /* include peripheral declarations */

extern void xcptn_xmpl(void);

int main(void)
{
volatile int counter = 0;

xcptn_xmpl (); /* Configure and Enable Interrupts */

/* Loop forever */
for(;;) {
counter++;
}
}

I did not add any codes to this project and that's an example S32DS project.

As mentioned, S32 Design Studio cannot connect to the S32R274RRUEVB. I would appreciate your help!

Hello,

Ok, but did you programmed anything to the uC?

Hello,

No, not a specific code. I tried only to execute a sample project as mentioned above.

Hello,

But, did you program it to the microcontroller RAM or Flash?

After programming did you verify that the micro is actually programmed? (looking at the memory / running the example code without debugger).

Or you just open project in the S32DS and trying to debug it?

To me it looks like your micro is empty.

Hello,

Thanks for your reply!


No, I just open the S32Ds and try to debug it. I would appreciate it if you could tell me how I can do it or send me some tutorials to make sure the ethernet connection works.

Hello,

well if you do not program micro, then you cant communicate with it.

here are some tutorials on how to do it in S32DS:

Hi,

As mentioned before and explained in this tutorial as well (https://community.nxp.com/t5/S32-Design-Studio-Knowledge-Base/How-To-Download-Install-Activate-and-U....

I tried to program the microcontroller but I am still getting the following errors same as before.

"Error in services launch sequence
PEmicro GDB Launch Failure : The GDB Server was not able to establish a connection to the target processor. Please check your connections and power. Verify that the launch settings in the Debug Configuration are accurate."

"Error in services launch sequence
PEmicro GDB Launch Failure : Unable to auto-detect debug hardware. Please specify on the command-line. If running from Eclipse, check the launch Debug Configuration settings. Halting."

Hello,

ok., there are 2 options I see here:

1. Your debug is not physically connected or your debug session is not configured properly.

2. your micro is dead. - which I don't thing is the case.

You can also try PE native GUI for debug. PPCNexus:

We have posted some example codes also here, you can try them in S32DS.

Hi,

The problem as I assumed, was not having the multilink debug probe. so, without that is impossible to program the micro for example over the Ethernet. Now, I wanna try to write a code that the micro receives random packets from my host PC over the Ethernet. The host PC as the sender uses a simple UDP client to send a packet to the micro. My problem is I cannot find any sources how to initialize the Ethernet port on the S32R274 micro, even in its datasheet there is no such a information. I could run an example for transmitting a signal to the CAN pins and works fine. I would appreciate your help!

Hi,

Thanks for your reply!

I will check it and will let you know.
