Because you are using a CFlash part you will need an external micro to put the device into programming mode (IAP is not available on this device) and just upload a custom bootrom.

You could adapt my prgrammmer to do this. (www.spen-soft.co.uk)

Or if ST would document the 'RAM Exec' function of Visual Programmer you might be able to do it from there, but you would still need a means of uploading the custom bootrom.

indeed,

that's just what I'm doing:

downloading code into RAM of st7 via ISP through another st7.

It's my thesis.

Why don't you just copy my programmer - www.spen-soft.co.uk

You could remove the flash and a few components and have a small pcb.

All the source and info is there

I CAN program the flash of an st7, I have a much simpeler programmer than yours..

But I need a program that writes to flash from RAM

If you can write to the flash then you must already have a bootrom which executes from RAM - I'm afraid I don't understand what you want.
