flash_cc2531
flash CC2531 USB dongle from your Raspberry, without Arduino nor CC Debugger.
prerequisites
A Raspberry Pi 3 with raspbian and wiringPi installed.
Getting Started
Download flash_cc2531 on your raspberry:
git clone https://github.com/jmichault/flash_cc2531.git
Connect the following pins of the debug port to the GPIO port :
- pin 1 (GND) --> pin 39 (GND)
- pin 7 (reset) --> pin 35 (GPIO24, BCM19)
- pin 3 (DC) --> pin 36 (GPIO27, BCM16)
- pin 4 (DD) --> pin 38 (GPIO28, BCM20)
and insert the usb dongle in a port.
A downloader cable CC and 4 Dupont line Female to Female are perfect for this purpose :
test by running :
cd flash_cc2531
./cc_chipid
it should return :
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 :
./cc_read save.hex
(takes around 1 minute).
To erase the flash :
./cc_erase
To flash file to cc2531 :
./cc_write CC2531ZNP-Pro.hex
(takes around 3 minutes).
