CCS/TMS320C6747: TMS320C6747 Boot From NOR Flash

Vijay Durga Prasad

Part Number: TMS320C6747

Tool/software: Code Composer Studio

Hi,

We are working on TMS320C6747 DSP. We made a test program which will print a string to UART in while loop(code mapped to L2 RAM) and downloaded to target using JTAG.

We would like to put the same code mapped to parallel NOR Flash connected to EMIF_A bus with chip select CS2. We have developed own flash utility to read / write flash and it is working fine.

We intend to use legacy mode / direct mode for boot. We are unable to locate startup files(before main execution) to customize the generation of flash version of image. Please help us.

Regards,

Vijay

We currently don`t have any example for legacy /direct mode. This mode was reserved for users migrating to C6747 from previous C67x DSP devices. The popular boot modes on this are SPI slave and parallel NAND which are AIS based boot modes.

I will check in our archives if there is any reference example that we can provide to help.

Regards,

Rahul
