Or get the chip to tristate the flash pins, contact them with something else and directly write the flash.
Or program the flash chip before soldering it in place.
Next time around have a connector, edge fingers, or pads for a pogo-pin spring contact jig.

Receive the PCB prototype from supplier. And see a CR mark on the board. What does it mean? Is it related to quality control?
E: The prototype provided by the supplier is good, but I found some solder joints are close to the PCB. Actually, how much width would be better?
A lot of DIY video mentions about ground via. I am just very curious about its function and necessity.
When assembling printed circuit boards, engineers have two main techniques to choose from: through hole and surface mount technology (SMT). In the early days, we dealt
Flawless PCB soldering is imperative for proper functioning of a printed circuit board. However, even experienced technicians can make small mistakes that lead to soldering defects.
SMT PCB assembly has become the most popular PCB assembly technology since the 1980s, and is now widely used in industries such as consumer electronics,
