a way to read the flash memory over UART without uploading a firmware to the target chip? (nrf52)

Question

nRF52832 / SDK V15 
 
 Hello, 
 Is there is way to read the nRF52 flash memory (any location if possible) over UART without uploading a program in the flash memory for that? (because there might be already a firmware there 
 we don't want to alter) 
 Basically, it's like asking how "nRF Connect/ Programmer" app can display the flash memory map... 
 My first guess would be to upload and run a small sketch in the RAM of the target chip and only in there. 
 
 Thanks.

I still don't understand what's your goal with this. If you just want to display the contents on flash somewhere, I'd advise you to just use JLinkExe, use the savebin command and open the bin file in Sublime Text using the HexViewer plugin. 
 If you're just doing stuff for educational purposes then the pynrfjprog library is fairly easy to use. I've used it in the past to automate flashing of entire panels, writing serial numbers to UICR, etc.
