AM2612: Problems related to flash erasure AM2612

zhou nanyi said:

After erasure, I also use UniFlash's memory function to read the flash address, specifically 0x60081000.

I don't think that memory read of external flash works (TBC by TI) so the numbers you see might be garbage and not representative of the actual flash contents. See this: AM263P4-Q1: UniFlash Feature Request : Memory Read of OSPI Flash - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums

This issue prevents the flash memory from booting correctly

Consider that the cause might not be the flash contents since Memory read does not work.

Hi Zhou,

After erasing via uniflash can you please try to read the flash using the memory browser feature in CCS. For this you can run an OSPI example that has DAC mode enabled in the sysconfig.

So once flash open is done, on entering the flash address in memory browser, the flash contents will be visible. This step can be used to ensure correct erase of flash

Once flash is done , the same method can be used to check the flash contents to ensure correct flashing of the code. 

Can you try this on your setup ?

Hi Kier,

      Sorry for the delay due to some matters. I may have missed some information to supplement. I am using our own control board instead of a LaunchPad. This flasher works normally for erasing, programming, and booting on the other 7 boards except this one. We use OSPI (4S)-Quad Read Mode for booting, but only one board encounters an issue during erasing. I ran the qspi_flash_io_am261x test program, and the result shows [Cortex_R5_0] All tests have passed!!, which indicates that my hardware is functioning properly.

Hi Zhou, 

After flashing the contents via uniflash, have you checked the flash dump? Please use the memory browser is CCS with dac enabled for checking the flash dump.

Also after flashing, when you are trying to boot, what is the osbervation ?

Aswin

Hi Aswin,

    After I erased the flash via UniFlash, I read the address 0x60081000 through UniFlash and got results all showing 0xFFFFFFEE. At this point, I couldn’t connect directly to CCS. After restarting, I connected to CCS and read the address 0x60081000 in the Memory Browser, with all results showing 0x00000000. I am using our own flasher. The code is as follows:

int main(void)
{
    int32_t status = SystemP_SUCCESS;

    System_init();
    Drivers_open();
    status = Board_driversOpen();
    DebugP_assert(status == SystemP_SUCCESS);

    Bootloader_UniflashConfig uniflashConfig;
    Bootloader_UniflashResponseHeader respHeader;

    gFlashAttrs = Flash_getAttrs(CONFIG_FLASH0);
    gFlashBuffSize = BOOTLOADER_UNIFLASH_MAX_FILE_SIZE;
    gFlashWriteOpcode = FLASH_OPCODE;

    if (status == SystemP_SUCCESS)
    {
        uniflashConfig.flashIndex = CONFIG_FLASH0;
        uniflashConfig.buf = gFileBuf;
        uniflashConfig.bufSize = 0; /* Actual fileSize will be parsed from the header */
        uniflashConfig.verifyBuf = gVerifyBuf;
        uniflashConfig.verifyBufSize = BOOTLOADER_UNIFLASH_VERIFY_BUF_MAX_SIZE;

        /* Process the flash commands and return a response */
        Bootloader_uniflashProcessFlashCommands(&uniflashConfig, &respHeader);
        gFlashStatus = respHeader.statusCode;
    }
    /* clear buffer to reset stale data if any */
    memset(gFileBuf, 0, BOOTLOADER_UNIFLASH_MAX_FILE_SIZE);
    OSPI_enableDacMode(gOspiHandle[CONFIG_OSPI0]);
    Drivers_close();
    System_deinit();

    return 0;
}

Alternatively, could you provide me with a demo program that can erase the flash correctly? 

I cannot upload my syscfg file and can only copy its content in text format as follows:

Hi Zhou,

After restarting in dev boot mode you can run an ospi example with DAC enabled in sysconfig (ospi_flash_io). After board drivers open, then only you should check the flash via the memory browser. 

Let me know if you have any confusion, I will provide with detailed steps to do this.

Regarding flash erase, what is actually required ? For flash erase you can check the flash erase API in ospi_flash_io example for instance. The example does demonstrate the erasure of flash

Aswin

Hi Aswin,

zhou nanyi said:

     You mean that after I erase the flash via UniFlash, I should restart in dev boot mode and run the OSPI flash IO example to check if the flash is erased?

Yes you are correct. You can run the example and pause after  flash has been opened. Since DAC is kept as enabled in sysconfig, you can enter the flash address in memory browser and see the state of flash.

Hi Aswin, 

Hi Aswin,

    I tried to use the example program from examples/drivers/boot/sbl_jtag_uniflash that you mentioned earlier to program the flash. After entering my file address, when I input the flash offset as 0x81000, why does the console display the function address as 0x70040020? If I enter 1 and press Enter, the program immediately prompts a verification error. The complete console output is as follows:

 Enter below command in CCS scripting console to load the file data to memory.
 AFTER the file load is done, enter '1' to continue ...

 [FLASH WRITER] Verify Failed !!!

Is the flash programming error caused by the incorrect first address? If so, how should I modify it? I noticed that 0x70040020 comes from 

uint8_t gFileBuf[FILE_MAX_SIZE] __attribute__((aligned(128), section(".bss.filebuf")));.

If the first address is correct, why can't the program be programmed into the flash? How to solve this problem? (I also cannot program the program using Uniflash. Even if Uniflash shows successful programming, the hex content read from 0x60081000 via CCS is obviously abnormal.) Thank you.

Best regards

Hi zhou, 

Apologies for the delay as I was OOO.

1. I assume that the flash configurations are correct as discussed in the previous replies. 

When using SBL JTAG uniflash, which boot mode is the board in ? Is it dev boot mode or ospi boot mode ?

Depending on the boot mode, the procedure for flashing is different. If it is dev boot mode, then the procedure is straight forward.

2. When you enter the flash offset and hit enter, the application asks to paste a load Raw command. Was the loadRaw command executed from the scripting console?

Inside the project, when the command 3 is given the operation type is chosen as flash verify. Based on the optype a command is issued which needs to be executed on the scripting console.

The address that is printed in the loadRaw command is actually the address of a buffer in RAM which holds the data. This is not the address to which flashing would be done. 

3. What is the issue that is faced while flashing from uniFlash ? Is the tools showing successful flashing ? Is the correct flasher being used ? The one that was used for erasure. Also did you try to flash the image multiple times using uniflash. There is a chance that the tool may not succeed in flashing the first time after flash erasure. 

Regards,

Aswin

Hi Aswin,

     My board is in Dev mode. Sorry, I might not have checked carefully. I need to copy the load Raw command provided by the program. I tried doing this: first copied the load Raw command prompted by the program, then entered 1, but got the same result.

When flashing the flash via UniFlash, the progress bar doesn't even move forward before an error occurs. I've tried several times, and the issue remains the same. The file I used to erase the flash is the "flasher_jtag_uniflash_am261x_lp" project in the SDK. The error message is as follows:

Hi zhou, 

I would like to confirm once again if the flash configurations are aligned. Are you able to run the ospi_flash_io example on the custom board ?

Once that is done, if the flash configuration of the flashers are also aligned then there should not be an issue.

Additionally, Can we get on a call and check the issue ?

Regards,

Aswin

Hi Aswin, 

     Sorry, I actually didn’t see your message from 6 days ago—probably because there was no notification from TI or I missed it. Coincidentally, I’ve also been busy with other things this week, so I may need to tackle this issue next week. I tried running the ospi_flash_io example before and it worked, but I’ll give it another try. I also hope to schedule a call to resolve this problem, though it will have to wait until next week. Thank you.

Best regards.

Hi Zhou,

No problem. We can have the call next week and see the issue. Meanwhile can you please tell which is the flash part is being used ?

Also, is it possible for you to share me the sysonfig that is being used. I just wanted to see the flash configurations

Regards,

Aswin

Hi Aswin

    It's S25FL128SA. Besides, I failed to upload the file on this website, so I'm sharing the modified sysconfig file for flasher_jtag_uniflash_am261x-lp_r5fss0-0 in code format. My sysconfig version is 1.23.0.

Best regards

Thank you for sharing the flash part and sysconfig.

Hi Aswin,

   Sorry for being occupied with another project these days. Would you be available for a brief discussion this Thursday or Friday? Is there any additional testing I need to prepare in advance? Alternatively, could we communicate briefly via email? At least I think it would be more efficient than the website :)

Best regards

Hi Zhou, 

Is it okay if we can have the discussion on Monday? Would that be feasible ? Yes we can communicate via email.

Regards,

Aswin

Hi Aswin,

   Could you please provide your email address? I have some new test findings to share.

Regards.

Hi Zhou, 

I have sent you an email. Please check it.

Regards,

Aswin
