No source available for "IVOR1_Vector() at 0x1001010"

[yalamandadosaky]

Hello, I am using s32 DS v1.1 , for developing my boot loader. Once I flashed the application code(.srec) at 0x010C0000 location with the boot loader code, I am moving my PC to this address. But, my code is not running and giving

No source available for "IVOR1_Vector() at 0x1001010"

I am not understanding why it is giving this.

Can any one help me how to solve above problem?

Hi,

There is really no issue with IVOR1. You are getting it because of one of the following situation occurred:

See you instruction assembly and track what exactly is core executing before you jump into IVOR1 vector.

This will bring more light into your investigation.

Sharing C functions really has no value for debugging this situation.

However sharing project/output file can help a lot if I can test it here.

regards,

Peter

Thanks Peter.

Microcontroller: MPC5748G
IDE: S32 Design Studio for Power Architecture. Version: 2017.R1. Build id: 171018

Software package used: NXP Sample project / DEVKIT-MPC5748G-LAB.zip / linflexd_uart

Software change made over demo software: Added a function call "initLINFlexD_1( 80, 57600 )" to initialize LIN channel 1 in the existing software. This exception could get triggered around the execution of "LINFlexD_1.LINCR1.B.INIT = 1;"

Questions:
1. What is the reason for this exception?
2. How to ensure that this exception doesn’t occur?

Would be glad to see this demo software changed to work on LIN Channel 1 without exception. This will help in doing the similar change over my software. Thanks again.

Peripheral clock gating wasn't set for LIN1 peripheral.

After setting "MC_ME.PCTL[51].B.RUN_CFG = 0x1", I do not see IVOR1 anymore.

Hi,

And do you have your source code loaded for IVOR1_Vector in symbols?

Peter

Hi petervlna‌, Thanks for your early response for my post, and I am new to this boot loader project , Really I dont know what are symbols  for IVOR1_Vector will be and the source code for the same , Can you suggest me how to check it ? and why these vectors are used.

Hi,

This makes situation quite complicated for you.

I recommend you to read a reference manual and core reference manual a bit to understand how IVORs works.

It is always good to state which processor are you using before starting any discussion. Same with debugger.

Hi，

I used S32 R2017 development on the S32R274 platform, and I encountered the same problem. I have tried many times and can't solve this problem. Here is the problem.

I will be grateful if you can help me solve this problem.

Hi. Have you got this IVOR1 Vector problem resolved? I am stuck with the same problem. Appreciate some help.

Hi

I have the same problem，whether your problem  been solved?

[bingwang312]

my problem is resolved successfully here.

I met same problem when i was trying to run the example program of SPI on DEVKIT MPC5744P Rev E. because the example program is using LINFlexD_1 for USB comm. to PC, this program is for DEVKIT MPC5744P Rev B.        One of the differences of Rev B & E is that LINFlexD_0 is for USB on board Rev E,  after changing the UART port for USB, IVOR1_Vector () problem pops up. After adding clock config for LINFlexD_0, problem is gone:

void peri_clock_gating (void)
{
MC_ME.RUN_PC[0].R = 0x00000000; /* gate off clock for all RUN modes */
MC_ME.RUN_PC[1].R = 0x000000FE; /* config. peri clock for all RUN modes */
MC_ME.PCTL98.B.RUN_CFG = 0x1; /* DSPI_1: select peri. cfg. RUN_PC[1] */
MC_ME.PCTL209.B.RUN_CFG = 0x1; /* DSPI_2: select peri. cfg. RUN_PC[1] */
MC_ME.PCTL204.B.RUN_CFG = 0x1; //LINFlexD_0: Select run config 1. bing added: to config for LINFlexD_0(USB) commu.
MC_ME.PCTL91.B.RUN_CFG = 0x1; /* LINFlexD_1: select peri. cfg. RUN_PC[1] */
}
