Write ST m29w800D

Hi, I need to program ST m29w800D, with rt 809 F, can someone help me or tell me some support links?
I would like to program the chip without removing it from the main-board.
So, I need to know exactly the connection points.
The chip is mounted on a MAG 250
Thank you .

Hi,
You can write through the CPU using the ISP or use a program from Toolchain panel for the respective processor if the programmer allows it.

Hi, Ciklon, and thanks for your attention.
If I understand correctly you say to write the chip ST m29w800D, through the cpu, in this case the cpu is: STI7105-BUD. The problem that we need to know the points where to insert the JTAG on the main-board. I downloaded something but it is not entirely understandable to me.

Hi Amennone,
I think the RT809F does not support ST processors via ISP
That document you have uploaded is about the following:
- Purchase of JIG based on FT2232HL
- Install the appropriate software and drivers
- Connect the JIG to the PCB to be programmed
- Explanation of working with the terminal program through which programming takes place.

But I did not see active links for 3 files.

The RT809F programmer support M29W800DB @ TSOP48, which can be programmed after being desoldering from the board, but you will need to have the PEB-1 expansion board for RT809F - www.aliexpress.com/item/PEB-1-Expansion-...84&priceBeautifyAB=0
