AM263P4: Uniflash SBL image for custom board

Koichiro Tashiro

Part Number: AM263P4
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

Hi,

My customer evaluates AM623P4 using control card (TMSDCND263P).
He understood OSPI flashing is possible with Uniflash using pre-build SBL (sbl_ospi.release.tiimage).

The customer will build their custom board based on control card. The same OSPI flash will be used on the custom board.
He understood the pre-build SBL accesses to on-board I2C EEPROM.
But their custom board does not have on-board EEPROM and he wants to know how to make SBL for the custom board.
Any guidelines?

Thanks and regards,
Koichiro Tashiro

Hi Koichiro,

1. Please make sure that the custom HW is designed as per the HW design guide lines mentioned here:(if possible, please have the HW review done by our HW apps team)

Yes if they are using the same flash chip then they can use the same Uniflash tool.

They can use the SBL application code as reference which is provided in SDK here:

https://software-dl.ti.com/mcu-plus-sdk/esd/AM263X/latest/exports/docs/api_guide_am263x/EXAMPLES_DRIVERS_SBL.html

The source code for the same can be found in folder: C:\ti\mcu_plus_sdk_am263px_10_00_00_35\examples\drivers\boot\sbl_ospi\am263px-cc\r5fss0-0_nortos

They can modify the sbl code as the custom hardware. If they do not have EEPROM, then they can simply remove eeprom from syscfg and comment out the code for EEPROM.
