read flash contents via serial

[sharkx]

Part of my developments for a custom OTA sequence, I would like to check the content that is written to the flash.
I would like to download the entire flash content from the module via the serial port.

Can it be done ? Thanks.

Never mind... I'm doing it over wifi.

Ok. So reading it over wifi helped me find one problem.
But I still "brick" the modules from time to time, and I'd really like to have a way to read that flash when this happens over the serial link.

Any help is appreciated. Thanks.
