MSPM0L1305: MSPM0L1305 - RAM self Test

Hi,

For MSPM0L1305, there also be ECC for Flash and parity checked SRAM.

Please refer to 1.3.2 of this document MSPM0 L-Series 32-MHz Microcontrollers Technical Reference Manual (Rev. D) (ti.com)

To test this function, you can write the data into unchecked SRAM, and read from parity checked SRAM, and then parity error will generate.

Zoey

Hi Zoey,

Thank you so much for the reply,

Could you please share any example code for the RAM Test

Hi,

Sorry we do not have RAM test demo code.

You can write from your side. If you have problems while writing code, you can start a new post or continue this thread to ask.

Thanks,

Zoey

Hi Zoey,

Thank you so much for the reply,I am not able to edit the startup file in CCS.can you Please help regarding this

Hi,

uncheck below in sysconfig.

Hi,

After uncheck I am getting this issue

Hi,

Please copy the old startup file into the project and then uncheck it.

Hi Zoey,

Sorry I am not clear about which old startup file you are mentioning.

Hi,

sorry for unclear information.

1. Please copy startup file from SDK: ...\ti\mspm0_sdk_2_00_01_00\source\ti\devices\msp\m0p\startup_system_files\ticlang  into your self project. For  example:

2. Then, uncheck in sysconfig

3. Build the project.

Regards,

Zoey

Hi Zoey,

Thank you so much for the reply

void Reset_Handler(void)
{
__asm(
"ldr r1, =0x20000000\n" // Start address of SRAM
"ldr r2, =0x20001000\n" // End address of SRAM
"mov r3, #0x0A\n\t" // Test pattern

"sram_test_loop:\n"
"cmp r1, r2\n" // Compare current address with end address
"bge sram_test_done\n" // Exit loop if end address reached

"str r3, [r1]\n" // Write test pattern to SRAM address pointed by r1
"ldr r4, [r1]\n" // Read back from SRAM address pointed by r1
"cmp r4, r3\n" // Compare read value with test pattern
"bne sram_test_failed\n"// Branch if mismatch

"add r1, r1, #4\n" // Increment address for next iteration
"b sram_test_loop\n" // Repeat loop

"sram_test_done:\n"
".global _c_int00\n"
"b _c_int00\n" // Jump to C initialization routine

"sram_test_failed:\n"
"b sram_test_failed\n"// Infinite loop or error handling for failed test
);
}

it is showing an invalid instruction in this two section.can you please help me regarding this

Hi,

Are you choose the right startup file?

Here is the demo project that I succeed to self write for startup file, you can base on that to develop your code.1323.empty_LP_MSPM0L1306_nortos_ticlang.zip

Hi Zoey,

Thank you for the reply

I am facing this issue, I'm not sure what I am doing wrong ,can you please help e regarding this. 

Hi,

Please use "movs" instead of "mov"

and "adds" instead of "add".

Zoey

Hi Zoey,

Thank you so much for the reply,

It is working now, but I want to know how to clear (clear assembly language)

Hi Zoey,

Thank you so much for the reply,It was very helpful for us

How to call a function in assembly

Hi,

Please refer to below code:

void Reset_Handler(void)
{
    /* Jump to the ticlang C Initialization Routine. */
    __asm(
        "    .global _c_int00\n"
        "    b       _c_int00");
}

Hi Zoey,

Thank you so much for the reply

we are trying to call toggle function, which has led blinking but led is not blinking. if i implement like this can you please help me regarding this ASAP

Hi,

Our Target is to call a function and blink the led from startup file. Can anyone Please help regarding this 

Hi,

If you just want to blink LED in startup file. Just use C language in reset_handler function(like Blink_LED()function)

Hi Zoey,

Thank you so much for the reply, for me it is not working. I have attached code for your reference

6136.gpio_toggle_output_LP_MSPM0L1306_nortos_ticlang.zip

Hi,

You are expecting like this?

It is not working for me 

No, please use below code:

void toggle(void)
{

        SYSCFG_DL_init();
        DL_GPIO_setPins(GPIO_LEDS_PORT, GPIO_LEDS_USER_LED_1_PIN |
                                            GPIO_LEDS_USER_LED_3_PIN |
                                            GPIO_LEDS_USER_TEST_PIN);
    while(1){}

}

If you not use while(1)

the code will run into main function, and GPIO will be initialized again.

Hi Zoey,

Thank you so for the reply,it is working from my side but I am not able to debug I have attached code for your reference,can you Please help me regarding this

4300.gpio_toggle_output_LP_MSPM0L1306_nortos_ticlang.zip

Hi,

If you want to debug step by step of assembly language, please change your code to:

For example:

from:

__asm(
            "ldr r1, =0x20000000\n" // Start address of SRAM
            "ldr r2, =0x20001000\n" // End address of SRAM
);

to:

__asm("ldr r1, =0x20000000\n"); // Start address of SRAM
            
__asm(""ldr r2, =0x20001000\n"); // End address of SRAM

Regards,

Zoey

Hi,

In this I want to check fail or done condition how to write in assembly 

Hi Zoey,

we are waiting for you reply

As I said before, please write assembly language separately for step-by-step debugging.

    __asm("sram_test_done:\n");
    __asm("b toggle()\n");
    __asm("sram_test_failed:\n");

Hi Zoey,

We are in final stage of RAM Test Part, But small issue we are facing I am not able to debug even after following your instruction

I have attached the code for your reference

I am facing this issue, could you please help me regarding this

7725.gpio_toggle_output_LP_MSPM0L1306_nortos_ticlang.zip

Hi,

Can you tell me which step or code line will cause you into this issue?

Thanks,

Zoey

Hi Zoey,

Thank you so much for the reply,after this line 53

Hi,

Will you go into Default_Handler?

Hi,

yes it is going into  Default_Handler

Hi,

It is because once your CPU run into this toggle and finish that, you didn't have next function to run. 

If you want to after this function and to run your main code, you can add

__asm(
" .global _c_int00\n"
" b _c_int00\n"
); 

into your toggle function, and then PC and changed to main function. But be sure you might need while(1); to end your function, or after you finish your main code, it will still run into Default_Handler
