AM2431: Guide to Choosing the right QSPI Flash part for AM243x QSPI boot

Hideaki Matsumoto

Part Number: AM2431

Hi,

We found the following thread “TDM4VM: Gude to choosing the right OSPI Flash part” by refering to "3.1.1.7. OSPI/QSPI in the Processor SDK Linux for AM64X.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/946418/faq-tda4vm-is-there-a-guide-to-choosing-the-right-ospi-flash-parts-that-are-supported-on-jacinto-7

How about QSPI Flash part for AM243x QSPI boot ? Is the above Guide able to apply to QSPI Flash as well ?

My customer is considering to use MT25QL128ABA1ESE-0SIT(Micron). Does AM243x support this part ?

Regards,

Hideaki

Hi Hideaki,

Yes, the E2E thread you have mentioned is applicable in AM243x case as well. From an OSPI driver (AM243x has an OSPI IP which can also support QSPI protocol) point of view that is a good reference to choose the flash part. However, flash driver in the SDK might not support a custom flash out of box. There might be improvements in the future, but as of now there is a developer guide which allows the customer to write the flash driver for their external flash. You can check it here -> https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_02_00_31/exports/docs/api_guide_am243x/CUSTOM_FLASH_SUPPORT_GUIDE.html

From the datasheet of the specific flash mentioned, I think they should be able to get it working on MCU+SDK for AM243x with minimal modifications of the flash driver which can be done by following the aforementioned guide.
