RTOS/TMS320C6672: How to boot directly from NOR Flash?

user4460891

Part Number: TMS320C6672

Tool/software: TI-RTOS

I use a C6672 designed circuit board. Can the nor flash boot directly through the EMIF interface be implemented? (No need to I2C EEPROM), is there a example? Thank you！

I've forwarded this to the EMIF experts. Their feedback should be posted here.

Hi,

Please check processors.wiki.ti.com/.../KeystoneI_Bootloader_Resources_and_FAQ, topic: How to do EMIF16 NOR Flash boot on C66xx devices? Example?

Please note that none of the TI evaluation platforms has a parallel NOR flash so we don`t provide an example for EMIF NOR flash in PRocessor SDK RTOS to support this usecase. However, this boot mode is validated using internal evaluation platforms that were used to checkout the SOC functionality.

We have through E2E forums shared the EMIF NOR flash writer code and summarized how the EMIF NOR boot image needs to be created to boot from the parallel flash. Here are customer posts that provide this information for these devices:
