TMS320VC5501 SPI EEPROM Boot Mode

Other Parts Discussed in Thread: TMS320VC5501

Hello great people,

Im a newbee just entering the DSP world.

Im trying to create custom board with TMS320VC5501 DSP, had some research and got to know that DSP gets booted from external slow NV-memory as oppose to microcontroller which have onchip flash memory. So I'hv chosen to interface serial flash thruogh MCBSP0 using SPI protocol with appropriate boot mode.

I also know JTAG is used for debugging purposes supporting hardware breakpoints in CCS.

My concern is how to program external EEPROM which is @ MCBSP0 port of DSP.

Is there any way that I can program EEPROM through JTAG?, Not sure how does Flashburn/SDFlash works !

There is some help available on http://processors.wiki.ti.com/index.php/SPI_Boot_on_5502_EVM

but it dosen't says how does <Burning the Image to SPI Flash | option 3> works

Thanks in advance

Hi,

The option 3 means:

You download a program into the DSP via JTAG and run the program. The program writes data to an external EEPROM via McBSP port.

- Hardware: an external EEPROM should support SPI interface and is physically connected to a McBSP port of the C5501.

- Software: the program uses McBSP port to write/read data to/from the EEPROM.

Regards,

Peter Chung

Thank you for prompt answer Peter I was looking for this confirmation.

I'll go ahead and finalise my PCB.

Meanwhile I'hv found some Refs supporting this discussion

I used this with some modifications on a VC5509A.
