TMS320F28388D: [CM] Boot image error

Part Number: TMS320F28388D

HI, sir.

My environment is as follow

-----------------------------------------------------

board : custom board

IDE : CCS 10.1

Compiler version : TI v20.2.2 LTS

Optimization : -O2 --opt_for_speed=3

debugger : XDS100v3

bootloader loc : SECTOR0,1 cmd setting -> FLASH_BOOTLOADER : origin = 0x00200008, length = 0x00007FF8 [ALIGN(8)]

app loc : SECTOR4~9 cmd setting -> FLASH_APP : origin = 0x00210008, length = 0x0005FFF8, [ALIGN(8)]

-----------------------------------------------------

Currently I have cm bootloader on flash 0, and I have succeeded in updating the FW. However, something strange was discovered.

When the txt size of the app becomes larger than one sector, the specific block address of the converted image is not an 8-byte address array.

I checked boot hex file and I found that address 0x21FFFF value was blank and next block adress was 0x220007. As far as I know, In the SCI_Boot kernel program block address must be input in units of 8 bytes so I expected 0x220008 but result is 0x220007. In details as follows

I don't know what I did wrong.

Thanks and regards.

Jude.

Hi Jude,

The description of the problem is not clear. Can you please explain this in more detail starting at the system level. How is programming being done?

Thanks,
Krishna

Hi Krishna,

Thank you for your fast reply.

I couldn't find to post an image in the comments, so I add an image this thread.

The first question I asked was the process of the red square dotted line.

I analyzed the 28377d's sci kernel program and confirmed that the images are written to flash in 16-byte units from CPU1. So, in the CM, Bootloader was implemented to write to Flash in units of 8 bytes using CM Flash_API. However, if the image itself does not have a continuous address of 8 bytes, there is a problem of redundant writing to the same address. In particular, this problem is found when the size of the image exceeds one sector.

            //64byte
           for(k = 0; k < (BUFFER_SIZE / 8); k++)
           {
               miniBuffer[0] = Buffer[k * 8 + 0];
               miniBuffer[1] = Buffer[k * 8 + 1];
               miniBuffer[2] = Buffer[k * 8 + 2];
               miniBuffer[3] = Buffer[k * 8 + 3];
               miniBuffer[4] = Buffer[k * 8 + 4];
               miniBuffer[5] = Buffer[k * 8 + 5];
               miniBuffer[6] = Buffer[k * 8 + 6];
               miniBuffer[7] = Buffer[k * 8 + 7];

               //
               //check that miniBuffer is not already all erased data
               //
               if(!((miniBuffer[0] == 0xFF) && (miniBuffer[1] == 0xFF) &&
                    (miniBuffer[2] == 0xFF) && (miniBuffer[3] == 0xFF) &&
                    (miniBuffer[4] == 0xFF) && (miniBuffer[5] == 0xFF) &&
                    (miniBuffer[6] == 0xFF) && (miniBuffer[7] == 0xFF) ))
               {
                    //
                    //clean out flash banks if needed
                    //
                    sectorAddress = FindSector(BlockHeader.DestAddr);

                    if(sectorAddress != 0xdeadbeef)
                    {
                        sectorSize = FindSize(sectorAddress);
                        oReturnCheck = Fapi_issueAsyncCommandWithAddress(Fapi_EraseSector,
                                (uint32 *)sectorAddress);

Hi, Vamsi.

Thank you for your reply.

Finally I solved this problem by splitting the sectors without merging them, and by using the'>>' syntax in the .text section.

The above phenomenon is found when the size of a specific obj file is more than one sector.

The previous command file is as follows.

if I only combined Flash, Based on what I understand, it would compile and create the image normally regardless of the size of the obj file.

But I am wondering if it is the right way to use it this way.

Thank you.

Jude,

Glad it is fixed now.

Splitting the sections and mapping a section to them is fine - no issues.

I am closing this post since the issue is closed. If you have further questions, you can open another post.

Thanks and regards,

Vamsi
