AM5729: AM5729 custom board QSPI issue

Rajesh War
Intellectual 525 points
Part Number: AM5729
Other Parts Discussed in Thread: UNIFLASH,

Hi,

Below is the steps followed to program QSPI flash using uniflash tool.

 

ERASING QSPI FLASH:
-------------------
> Power cycle the board and let it boot from qspi.
> Open ccs.
> launch the target configuration but don't connect it.
> right click on the core (a15) -> open gel files view -> right click in the gel/script section -> remove all. Basically, you have to connect the core without gel files.
> then connect the core and load and run <path\to\uniflash\root_folder>\processors\FlashWriter\idkAM571x\uart_idkAM571x_flash_programmer.out.
> You can see CCC in the serial console.
> Note down the port number and close the console.
> Open CLI from uniflash root folder and give below command - dslite.bat --mode processors -c COM4 -e 10000 -d 2 -o 0.

 

 

command line qspi flash IDK:
---------------------------

> cd C:\ti\uniflash_6.2.0

> dslite.bat --mode load --config=C:\ti\pdk_am57xx_1_0_17\packages\MyExampleProjects\MMCSD_idkAM572x_armTestproject\targetConfigs\IDK_AM572X.ccxml -f C:\ti\uniflash_6.2.0\processors\FlashWriter\idkAM572x\uart_idkAM572x_flash_programmer.out -n 8

> dslite.bat --mode processors -c COM19 -f C:\ti\pdk_am57xx_1_0_17\packages\ti\boot\sbl\binary\idkAM572x\qspi\bin\MLO -d 2 -i 1 -o 0

> dslite.bat --mode processors -c COM19 -f C:\ti\pdk_am57xx_1_0_17\packages\ti\boot\sbl\binary\idkAM572x\idk\led_TEST -d 2 -o 80000

 

 

When we are executing highlighted line of the above script in our custom board, it’s hanging and no response in tool. We tried to program same custom board MLO file flashing in EVM and it’s working fine.

 

Main hardware change between custom board and EVM is only the size of the flash.

 

EVM -  S25FL256S

Custom Board - S25FL512SAGMFIR10

 

Do we need to do any modification for working with different flash in uniflash tool?

 

Processor – AM5729

PDK - pdk_am57xx_1_0_17

Regards,

K.A.Rajeshwar.

    Hi,

    there are few debugging cases you can follow here:

    • Is your SD boot is working fine. If so, whether it is the default MLO or you have to built it freshly against your custom Board. 
      • I guessed, you must have built it for your custom board taking new board library into account. If so, you have to rebuild the qspi MLO again, taking reference with the modification what you have did for MMCSD MLO.
    • You can also check SPI interface first (preferably diagnostic test or driver example), to validate read/write access to the interface.

    you can see below useful documentation also:

    Hi Anubhav,

             > We created new MMCSD MLO and QSPI MLO for custom board. MMCSD MLO is working in custom board for SD card boot-up. QSPI MLO we unable flash in Uniflash method. it's stopped above we mentioned in our quary.

              > SPI read/write interfaces we tested using QSPI pdk example file .

    what about SPI addresses, are the starting addresses are same for custom and TIEvms?

    For flash related code, you should probably update board/src/flash folder.

                   2) i checked  MLO AM572x IDK. here i attached AM572x IDK MLO file as MLO.txt format.

    • Can you check manufacturer and device id by doing register read using board lib api and match it with ids given in datasheet.
    • If succeeded, run the qspi diag test and share the log.
    Rajesh War said:
    2) i checked  MLO AM572x IDK. here i attached AM572x IDK MLO file as MLO.txt format.

    This one is working on TIevm.

    In case of sd boot, is the same card is booting on both custom board and TIevm.

    Hi Anubhav,

          1) we are able to read manufacturer and device id by doing register read using QSPI_BasicExample_idkAM572x_armExampleProject. but when we use UNIFLASH method  not able to flash MLO. we suspected in UNIFLASH method, we are not able write properly in QSPI memory space. kindly check and help us for resolve this issue.

           2) SD card boot, for custom board and TI evm we are use different card wth different MLO and app. For QSPI also we generated different MLO for QSPI for custom and TI evm.

    Read/write is successful?

    Rajesh War said:
    when we use UNIFLASH method  not able to flash MLO.

    you have to flash uart_XXXAM57XX_flash_programmer.out first before MLO.

    • which .out you are flashing.
      • I think you are using uniflash/processors/FlashWriter/idkAM572x/uart_idkAM572x_flash_programmer.out. If so, this might be the issue. You are updating board/src/flash/ inside pdk and running the script from uniflash, these two will are two different folders. After updating the flash folder build the library and flash the .out generated at pdk_am57xx_X_X_XX\packages\ti\board\utils\uniflash\target\bin\idkAM572x\. This binary is linked with your updated board library.
    • are you seeing CCC on the console.

    As mentioned here, have you tried with binary at board/src/utils/uniflash/target/bin folder. Make sure this binary is not the prebuilt one. Rebuild this binary, then only it will take your flash changes.

    Hi,

    Can you check the following:

    • After 'Header Transfer Complete!' does flash programmer send 'C'. Can you check on serial console without resetting the board. If flash programmer sends 'C', then QSPI init is successful and waiting for flashing image from uniflash. (If 'C's are not coming at 115k baudrate, then can you check on 3M baudrate).

    (Note: Flashing address should be the start of sector)

    Its hard to tell like this.

    My doubt is QSPI(new part number) integration only. Thats why, i suggested to first validate it with linux. From linux please try raw read/write over the whole memory(including boundary addresses).

    Hi Sathish,

    'sf probe' command will initialize the QSPI in U-Boot.
    You can use:

    sf read $loadaddr QSPI_Offset_in_bytes size_in_bytes

    The above will dump all the contents from QSPI_Offset_in_bytes of size size_in_bytes to RAM loadaddr.

    You can check the whole contents there in U-Boot itself.
