Hi, TI engineers

Thanks to your help, I have managed how to load program into OSPI flash.

But after I load it into OSPI flash, it didn't work.

could you help confirm which step is wrong?

My procedure is as below

①I load the SBL(.tiimage file) into the 0x0000 address of OSPI flash (file size:132639Bytes)

②I convert the .out file into app by AM65xxImageGen.bat.

③I load the app into the 0x80000 address of OSPI flash (file size:285516Bytes)

④I turn the SW3.1 to ON and all other SW to off. Perhaps there is something wrong with my setting of BOOTMODE OSPI

⑤Power on, I find it didn't run(there is nothing output from uart port).

Best Regards

Hope,

If you are using Processor SDK RTOS 5.02 then please check the migration guide here:

For OSPI boot, the flash offsets have changed. “sysfw.bin” needs to be programmed into OSPI flash at offset 0x40000 (new for this release), along with “sbl_ospi_img_mcu1_0_release.tiimage” at offset 0x0 (no change from previous release) and the “app” at offset 0xA0000 (was 0x80000 previous release). For details please refer Programming the OSPI flash

Let me know if this resolves your boot issue.

Regards,

Rahul

PS: Also set the boot mode pins to the following::
