TMS320F280025: HW CRC programming or code

HK Woo,

As discussed in the call, I assigned this to our CRC expert that can guide you further.  Please expect a reply in a day or two.

Thanks and regards,
Vamsi

Hi HK Woo,

The vcrc example you mentioned already has the comparison of linker generated CRC and the VCRC computed CRC. The example showcases it for a single section. But you can expand the same for entire flash as well

In cmd, if you need CRC for the entire flash, you can group them together as follows:

GROUP { /* GROUP memory ranges for crc/checksum of entire flash */

/* BEGIN is used for the "boot to Flash" bootloader mode */
BEGIN : origin = 0x080000, length = 0x000002

/* Flash sectors */
FLASH0 : origin = 0x080002, length = 0x001FFE /* on-chip Flash */
FLASH1 : origin = 0x082000, length = 0x002000 /* on-chip Flash */
..

} crc(_ccs_flash_checksum, algorithm=CRC32_PRIME)

The CRC table is available in the section .TI.memcrc instead of .TI.crctab(which is used if crc in sections)

You can refer to the TMS320C28x Assembly Language Tools User Guide for more details.

I reviewed the project 2838_vcrc_crc_32 again. I still don't understand a mechanism using by the project at the moment

1. Per my understand on CRC checking. It is necessary to do CRC calculation block by block until calculation of CRC over entire flash which need to checked is completed and then compare the golden value of CRC.

However, it is not in the project. It compares the value inside the for loop and increase the values of pass / fail number

    pLinkerCrcTable  = &linkerCrcTable;

    // Step 2: Get the CRC results from the linker CRC table
    for(i = 0; i < pLinkerCrcTable->num_recs; i++){
        // Get the current CRC record
        linkerCrcRecord = pLinkerCrcTable->recs[i];
        // Get the linker generated CRC
        crcResultLnk    = linkerCrcRecord.crc_value;
        if(linkerCrcRecord.crc_alg_ID == CRC32_PRIME){ //0x04C11DB7
            (crcResultLnk == crcResultVcu_1)? pass++ : fail++;
            (crcResultVcu_1 == crcResultC_1)? pass++ : fail++;
        }else if(linkerCrcRecord.crc_alg_ID == CRC32_C){ //0x1EDC6F41
            (crcResultLnk == crcResultVcu_2)? pass++ : fail++;
            (crcResultVcu_2 == crcResultC_2)? pass++ : fail++;
        }else{
            fail++;
        }
    }

Futhermore, the project define constant

static const uint16_t testInput[NWORDS] = {
    0x4001, 0x8002, 0xC003, 0x0004, 0x4005, 0x8006, 0xC007, 0x0008,
    0x4009, 0x800A, 0xC00B, 0x000C, 0x400D, 0x800E, 0xC00F, 0x0010,
    0x4011, 0x8012, 0xC013, 0x0014, 0x4015, 0x8016, 0xC017, 0x0018,
    0x4019, 0x801A, 0xC01B, 0x001C, 0x401D, 0x801E, 0xC01F, 0x0020,
    0x4021, 0x8022, 0xC023, 0x0024, 0x4025, 0x8026, 0xC027, 0x0028,
    0x4029, 0x802A, 0xC02B, 0x002C, 0x402D, 0x802E, 0xC02F, 0x0030,
    0x4031, 0x8032, 0xC033, 0x0034, 0x4035, 0x8036, 0xC037, 0x0038,
    0x4039, 0x803A, 0xC03B, 0x003C, 0x403D, 0x803E, 0xC03F, 0x0040,
};

I think that it is content stored in flash and it calculate the CRC of testInput

Please correct me if I am wrong or mechanism using in the project is different from it.

2. Which part of code read the linker generated CRC value for the constant "testInput"?

Hi HK Woo,

I have updated a basic led blinky example to include CRC check using VCRC. This is tested on F2838x, but you can use this as a reference for F28002x. The VCRC IP on these devices are the same.

Please try using this and let us know if you face any issues. I have added comments in the code which I believe would answer your questions.

I have added supported for all the CRC algorithms supported by linker. You can make changes as necessary.

Thanks for your example, it is more clear to me. I will try it and let you know that result.

Hi,

Which version of CCS compiler are you using? MEMRANGE_CRC_TABLE is defined in the compiler header. 

The feature "Generate CRCs over memory ranges" was added in CCS compiler 21.6.

Prior to that linker only supports CRC computation on a specific section.

Is your requirement to compute CRC for entire flash or only for specific sections?

Regards,

Veena

Also note that I have excluded few bytes of Flash memory from CRC calculation.

Please find screen capture for your information

I need to specific section. I have modified a link cmd as below.

  MEMORY SECTION

   GROUP
   {
       BEGIN               : origin = 0x080000, length = 0x000002

    }crc(_ccs_flash_checksum, algorithm=CRC32_PRIME)
    FLASH_BANK0_SEC15_CRC: origin = 0x08FF98, length = 0x60

Add .TI.memcrc : >FLASH_BANK0_SEC15_CRC in SECTIONS.

It is same approach as your code

Hi,

CCS compiler version 20.2 does not support the feature "Generate CRCs over memory ranges". This is available in v21.6.

v20.2 supports CRC computation for sections.

Is your requirement to compute CRC for the entire flash or for specific code sections?

Regards,

Veena

This is the release notes of CGT v21.6:

software-dl.ti.com/.../README.html

Hi Veena

I need to compute a specific range of flash but it is almost entire flash range.

You can find that my link cmd file. I grouped 0x080000 to 0x08FF98 and reserved 0x08FF98 to 0x08FFF8 for crc_table.

I need to check CRC from 0x080000 to 0x08FF98

How to downlod V21.6? I use CCS to check any update, but it said no update find.

BR

HK Woo

CCS update should ideally show the new compilers.

If you don't find it, you can directly install it from here : https://www.ti.com/tool/download/C2000-CGT-21

Veena,

I compared a project 2838x_vcrc_crc_32 and found that there is a file c28x_vcrc_library_fpu64.lib and then add it to

Property -> CCS build -> C2000 linker -> File Search path with C:\ti\c2000\C2000Ware_3_03_00_00\libraries\dsp\VCU\c28\lib\c28x_vcrc_library_fpu64.lib.

Errors are fixed. Please advise is it correct?

Yes, that is right. You need to include the VCRC library to use these functions.

Regards,

Veena

Veena

Thanks for your confirmation. It seems that the function returned  flash CRC (CRC.crcResult) is section by section. I just want to confirmation it. Section by Section is OK to me. I just want to confirm it and hence prepare a document for  safety application about the function.

BR

HK Woo

Hi HK Woo,

Let us use the word memory blocks to avoid confusing it with the compiler generated sections.

In the example, I have grouped multiple memory blocks to compute CRC by linker. In the application, I am parsing through the linker generated CRC record, to identify different memory blocks, its start address and size. I did this to make it generic. If you know the start address and the total size, you can use that for VCRC calculation directly, without reading it from CRC Table.

For example:

   GROUP
   {
       BEGIN               : origin = 0x080000, length = 0x000002
       FLASH_BANK0_SEC0  : origin = 0x080002, length = 0x000FFE    /* on-chip Flash */
       FLASH_BANK0_SEC1  : origin = 0x081000, length = 0x001000    /* on-chip Flash */
     } crc(...)

You can compute CRC using a single VCRC run function call, with start address as  0x080000 and nMsgBytes (in bytes) s 0x4000. Note that the parameter nMsgBytes is uint16_t, so care should be taken not to give higher values.

Regards,

Veena

Hi Veena

I got several of problems as I put the code to my real project.

1. Link cmd file.

a. I modified my link cmd file based on example link cmd. Error is generated during compile my code (without any modification on code, just link cmd file).

>> Compilation failure
makefile:173: recipe for target 'Mercury_Buck.out' failed
"../device/28002x_generic_flash_lnk.cmd", line 88: warning #10068-D: no matching section
error #10471-D: Ignoring empty output section "dclfuncs" in memory range FLASH_BANK0_SEC8_9_10; objects in CRC range must be non-empty.
error #10010: errors encountered during linking; "Mercury_Buck.out" not built
gmake[1]: *** [Mercury_Buck.out] Error 1
makefile:169: recipe for target 'all' failed
gmake: *** [all] Error 2

b. I commented "dclfuncs". No error generated.

    GROUP
    {
        isrcodefuncs
        //dclfuncs
    }    LOAD = FLASH_BANK0_SEC8_9_10,
         RUN =  RAMLS4567,
         LOAD_START(isrcodefuncsLoadStart),
         LOAD_SIZE(isrcodefuncsLoadSize),
         LOAD_END(isrcodefuncsLoadEnd),
         RUN_START(isrcodefuncsRunStart),
         RUN_SIZE(isrcodefuncsRunSize),
         RUN_END(isrcodefuncsRunEnd),
         ALIGN(4)

Please advise about it.

2. Then I move forward to add VCRC code which works fine in example (dclfuncs is still comment)

a. Find errors as below

>> Compilation failure

**** Build Finished ****

As I comment below codes, errors are not found

//    CRC.init(handleCRC);

    // Get the CRC results from the linker CRC table
//    for(i = 0; i < pLinkerCrcTable->num_recs; i++)
//    {
//        // Get the current CRC record
//        linkerCrcRecord = pLinkerCrcTable->recs[i];
//
//        // Compute CRC for the current memory range
//        CRC.nMsgBytes  = linkerCrcRecord.size * 2;
//        CRC.pMsgBuffer = (void *)linkerCrcRecord.addr;
//        CRC.seedValue = CRC.crcResult;
//        CRC.run(handleCRC);
//    }

Any comment?

HK Woo

1. I am guessing it could be because the application does not have a section named dclfuncs. Or its not being used, hence compiler creates an empty section named dclfuncs.

2.This error is strange. For some reason, including VCRC library is causing some compatibility issues with others. Can you confirm that all the libraries and the application are built with EABI format? Also, can you send the console output for CCS build with CRC code and without CRC code

Regards,

Veena

Hi Veena

1. Could we have webex meeting? We can fixed it on-line

2. Please find console output without VCRC code as below

Let me loop in the compiler experts.

Veena

Sure, I can setup a WebEx meeting, let me know a convenient time.

Since this issue is more from compiler side, let us see what they respond.

Veena

Veena

Where are you located?

I accepted your request

I have sent you private message

Hi Hung Kai Woo,

I see you mentioned c28x_vcrc_library_fpu64.lib. In case of F28002x, you should use c28x_vcrc_library_fpu32.lib.

The f2838x supports fpu64 whereas f28002x only supports fpu32.

Regards,

Veena

Hi Veena,

Im trying to generate linker crc for a range of flash for the same part number and I found this forum very useful. I just have one question adding to this if you can verify what is the VCU support option selected under the processor option in the properties? Is it vcrc or vcu2?

Regards,

Harsha Dsouza
