QSSI-Flash code execution

Hi Everyone.

I have a question.

I bought DK-TM4C129X which has Quad SSI to 512 Mbit flash.

Dose it do code execution directly from Flash memory?

Can you help me?

Hello Hiroyasu,

The 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.

Hi, Amit

Thank you for your reply.

and If I copy the image into internal SRAM, Do you have any sample code?

regards,

Hiroyasu

Hello Hiroyasu,

Yes, copying the image into internal SRAM and then executing it would work. However do make sure that the when you build the image it should be referenced to the internal SRAM address, otherwise it would jump back into flash if the cmd file contains the flash address.

Unfortunately, I do not have a code ready to use.
