CCLoader
========

Burn CC254x firmware using an Arduino board.

Note!|
----|
This is fork of the original https://github.com/RedBearLab/CCLoader that adds functionality to also read flash (and to check chip ID/revision). Pull request (https://github.com/RedBearLab/CCLoader/pull/27) for these changes has been submitted, so you may be better off using the original version as this version likely won't be regularly updated (if these changes end up in the mainline).
Help needed, only Linux executable has been updated with new functionality Windows and MacOSX versions need these changes merged to them before they work against the new updated Arduino sketch.



## Burn CC254x firmware using an Arduino board.

1. Load the CCLoader Arduino sketch to the UNO board.
2. Wire the pins:
![image](CCLoader.jpg)
3. Use CCLoader.exe to load the Demo.bin to the UNO board and the board will burn the firmware to the BLE Mini.

## New functionalty

* ccloader executable now has three commands/modes:
* id - Read chip ID/Revision
* read - read/dump flash memory (save/backup flash memory before overwriting it, if flash is not protected)
* write - write flash memory

Note! Currently only Linux executables is updated with the new functionality. Windows and MacOSX executables will need to be updated with changes made to Linux executable before those can be used...

## Syntax
```
Usage: ./ccloader_tng <serialport> <device> <command> [<bin file> [<verify> | <read_start_block> <read_blocks>]]
Examples:
Read Chip ID: ./ccloader_tng /dev/ttyUSB0 1 id
Write Flash: ./ccloader_tng /dev/ttyUSB0 1 write flash.bin 1
Read Flash: ./ccloader_tng /dev/ttyUSB0 1 read dump.bin 0 512
Example: ./ccloader_tng /dev/ttyUSB0 1 id
<device>: 0 -- Default (e.g. UNO)
1 -- Leonardo/Mini Pro/etc...
<verify>: 0 -- No verify (default)
1 -- Verify (when flashing)
<read_stat_block>: 0 -- Start flash dump from block (0 = beginning of the flash)
<read_blocks>: 512 -- How many blocks to read (512 = 256Kb)
```

## Query chip ID

```
# ./ccloader_tng /dev/ttyACM0 1 id
Serial port: /dev/ttyACM0

# ./ccloader_tng /dev/ttyACM0 1 write ../../Bin/Demo.bin 1
