# flash_cc2531 | ||
flash CC2531 USB dongle from your Raspberry, without Arduino nor CC Debugger. | ||
|
||
## prerequisites | ||
A Raspberry Pi 3 with raspbian and [wiringPi](http://wiringpi.com/) installed. | ||
|
||
## Getting Started | ||
|
||
Download and unpack the archive on your raspberry. | ||
Connect the following pins of the debug port to the GPIO port : | ||
pin 1 (GND) --> pin 39 (GND) | ||
pin 7 (reset) --> pin 35 (GPIO24) | ||
pin 3 (DC) --> pin 35 (GPIO27) | ||
pin 4 (DD) --> pin 35 (GPIO28) | ||
|
||
and insert the usb dongle in a port. | ||
|
||
test by running : | ||
```bash | ||
./cc_chipid | ||
``` | ||
it should returns : | ||
``` | ||
ID = b524. | ||
``` | ||
If you see 0000 or ffff, something is wrong and you should probably check your wiring. | ||
|
||
## Usage | ||
To save the content of the flash to save.hex file : | ||
```bash | ||
./cc_read save.hex | ||
``` | ||
(takes around 2 minutes). | ||
|
||
To erase the flash : | ||
```bash | ||
./cc_erase | ||
``` | ||
|
||
To flash file to cc2531 : | ||
```bash | ||
./cc_write CC2531ZNP-Pro.hex | ||
``` | ||
(takes around 3 minutes). | ||
