Original question:

TM4C1294NCPDT: Add external flash

TM4C1294NCPDT: QSSI External Flash/RAM

Hello,

My name is Simeon Aleksandrov, I am an FAE intern at TI.

I had a question about using external Flash and RAM on the TM4C1294NCPDT. While it EPI is recommended for use, especially since it supports contiguous memory access independent of data bus width. Is it possible to run code directly from Flash using QSPI/QSSI?

Best Regards,

Simeon Aleksandrov

    Hello Simeon,

    For NAND Flash on QSSI, TM4C129 cannot execute the code from the external flash over QSSI. You would need to have a boot loader to copy the image from the external Flash to internal flash or SRAM and then execute it.
