Other Parts Discussed in Thread: AM2432

Hi,

I'm using the am2432 with the mcu_plus_am243x_sdk.

I'm using the OSPI Boot mode to load my app into DDR.

I see that my app in OSPI FLASH is always at address=0x8000. (I'd like to be able to use other address)

Which SBL loader project should I modify and at which file, for having my app copied to the DDR from other FLASH address ?

Thanks,

Eli

You should modify sbl_ospi project and in the syscfg you will find a field for App Image offset. You are required to modify that.

Of course ensure the during the flashing, your application image needs to be at another location.

I hope this helps.

Hi Aakash,

TI's example ospi_flash_io - works ok I can erase write and read the flash.

When I do the same code in my project

It crashes after ospi_v0.c :1464

1464 OSPI_writeFifoData(attrs->dataBaseAddr, pSrc, wrBytes);

1465

1466 pSrc += wrBytes;
1467 remainingSize -= wrBytes;
1468 }

1469

1470 if(wrFlag == 0U && OSPI_waitIndWriteComplete(pReg) != 0)
1471 {
1472 wrFlag = 1U;
1473 status = -1;
1474 }

OSPI_waitIndWriteComplete(pReg) returns -1;

Please advice how to proceed ?

Thanks,

Best Regards,

Eli

Let's track this into another E2E.
