Other Parts Discussed in Thread: UNIFLASH

Hi

May I check some question about AM64x boot from OSPI?

--

Question 1

My customer want to boot from OSPI that write .bin directly (not use like uart uniflash tool).

Is the Secondaly bootloader start address(OSPI's address) 0x00?

And Is there any guide for flashing .bin to OSPI memory?

--

Question 2

Is there any way (another than UART output) for use output log that use for debugging boot Process?

Thanks,

GR

    Hello GR san,

    1/ What .bin files are we talking about here?

    2/ You may use CCS for debugging purposes.

    Regards,

    Hi Prashant san,

    Thanks to your support.

    1/ .bin file is SBL image.

    My customer is using sbl_ospi.rerese.hs_fs.tiimage.bin

    2/ My customer is testing custom boad,

    So there is not UART port, and boot from OSPI that already flashed .bin(SBL image)

    Is there snything way to see boot log without JTAG port?

    Best regards,

    GR

    Did the customer rename the sbl_ospi.release.hs_fs.tiimage to sbl_ospi.release.hs_fs.tiimage.bin and then flashing this renamed image?

    The boot logs should be coming on UART. Also, you can use an external debugger if you have the compatible pin interface on the board.

    I am currently checking to my customer.

    I understand that boot log will output only UART.
