AM6548: OSPI Boot issue

Artem Boyarchuk
Intellectual 370 points
Part Number: AM6548

Hello,

We are developing a custom device based on the AM6548 SR2.0 processor with OSPI flash MX66UM1G45G that connected as OSPI flash in dev board.

For development, we use the Linux SDK for AM65x 07_00_01

We have checked the flash in u-boot and linux, it works. We have flashed images (tiboot3.bin, tispl.bin, u-boot.img, sysfw.itb).

But when we try to boot from OSPI the board doesn't load. We set right boot configuration according to documentation. 

Could you tell us what might be causing this problem?

Does OSPI BOOT for AM6548 SR2.0 work right?

Best regards,

Artem

    Hi Artem,

    I will try this on SR2.0 board and get back to you in couple of days.

    Hi Artem,

    This seems like an issue on SR 2.0. I do not see any prints from u-boot/SPL when i try to boot from OSPI. The same is working
    very well on SR 1.0. I have reached out to internal teams on this. I will provide feedback as soon as i hear back from them.

    Best Regards,

    Hi Artem,

    I have intimated the internal teams regarding this issue. This will be fixed most likely
    in the next release. I believe you do not see any traces on UART when you boot from OSPI.

    Let me know if you have different observations.

    Best Regards,

    No, We are seeing driving chip select pin, clock and data, but system is not loaded and we see nothing in console

    Hi Keerthy,

    Sorry for the delay. We have checked the binaries that you sent and the binaries didn't solve the problem, I see nothing in debug console.

    Best Regards,
    Artem

    Artem,

    With the attached binaries i was able to boot to u-boot prompt. Can you please share the commands
    that you used to flash to OSPI and the outputs as well?

    Are you using fatload mmc or tftp?

    Best Regards,
    Keerthy

    Could you send Boot Mode Pins configuration that you used ?

    Artem,

    I again tried the attached pg2.0.zip in earlier reply from me: https://e2e.ti.com/support/processors/f/791/p/941230/3497369#3497369

    Here are the commands i used:

    sf probe
    sf erase 0x0 0x1000000

    fatload mmc 1 ${loadaddr} tiboot3.bin; sf update $loadaddr 0x0 $filesize; fatload mmc 1 ${loadaddr} tispl.bin; sf update $loadaddr 0x80000 $filesize; fatload mmc 1 ${loadaddr} u-boot.img; sf update $loadaddr 0x280000 $filesize; fatload mmc 1 ${loadaddr} sysfw.itb; sf update $loadaddr 0x6C0000 $filesize

    Keerthy,

    Thank you for reply

    We have resolved the issue and now U-boot can be loaded from OSPI Flash.

    To do this, we have set special Boot Mode Pins configuration for our OPSI Flash and added supporting our SPI Flash driver into SPL

    Artem
