AM2634: External flash option S25FL064L can I use the SBL flashing program of the SDK?

Part Number: AM2634
Other Parts Discussed in Thread: SYSCONFIG

Hi Team,

There's an issue from the customer need your help:

When debugging with the AM263 CC board, I went into QSPI boot mode using the SBL of the SDK to successfully flash the program. However, the external flash used by the CC board is S25FL128S, and the flash configuration in sysconfig is only S25FL128S. If I use S25FL064L external flash, do I need to reconfigure and flash? Can these two chip programming methods be used in common?

Could you help check this case? Thanks.

Best Regards,

Ben

And Does the sbl_qspi.release.tiimage file have a corresponding project? Because the 128M flash read and write speed requirements are different for the 64M flash on CC boards, I would like to ask if the configuration can be modified to flash to 64M. Currently, the SBL file is programmed into 64M flash and cannot run.

Please refer this documentation for support of a custom flash device.

Flash Read Write Tests in the example mentioned above after your SFDP table is updated.

If you see no errors, you won't have a lot of problems booting SBL''
