Ask for help how to write firmware to DSP chip

(1/3) > >>

Hello I hope you All will be Fine.

So I have a microprocessor board(kind of CPU for the Whole System) in which the Processor is Texas Instrument TMS320F2812GHHA. This processor is getting hot when we turn the power on. Below Please find the Datasheet for the Processor.

I plan to buy a new TMS320F2812GHHA.But I don't know how to write the firmware into this new chip.I obtained a .x00 upgrade file. I guess this is the firmware inside the DSP chip.
Looking at the pcb circuit board, I found that the edge of this chip looks like a JTAG interface.

If you know how to write the firmware please let me know, thanks

You could use UniFlash https://www.ti.com/tool/UNIFLASH together with a XDS110 Jtag probe. https://eu.mouser.com/ProductDetail/Texas-Instruments/LP-XDS110ET

Before anything else, I would check all the power supply voltages and some other things. It would be bad if the new chip gets fried due to some kind of defect.

Thank you for your reply.
Do you mean to use UniFlash as the programmer software?
Install the newly purchased TMS320F2812GHHA (no firmware inside) on the PCB circuit board,Then connect the JTAG interface and PCB circuit board through XDS110,Is this what writing firmware means?

As a side note, does UniFlash support files in the format (.x00)? XDS110 seems to be available in V1, V2, and V3. Which version should I choose?

I separated the TMS320F2812GHHA (original chip), 5V and 3.3V power supplies and GND, and they disappeared after short circuit, so I think TMS320F2812GHHA has been damaged.
