Hi, 

   

I'm working since many time on PSoC5LP and I'm wondering if there is the possibility to retrieve an existing firmware  (as hex file) on PSoC using the programmer or similar, before flashing the new one. Could anyone help me ?

   

Regards

The PSoC programmer has a "read" option that allows to read the content of a PSoCs flash memory. This only works if the chip is not read -protected (then the Flash can only be overwritten).

Yes, but I try to get from this "read" an hex file to save and eventually re-flash after...is it possible ?

Would be good when you tell us a bit more about because:

   

When you programmed the PSoC yourself, you already have the .hex file

   

When you did not program the chip, parts of it might have been protected from reading and the results you receive may be wrong.

   

So what exactly is the reason why you want to read-out the chip-contents?

Before download a new fw, I'd like to save the old fw from the mcu...this because the operation is made not in a laboratory but outdoor...
