ZNP firmware for cc253* has a built-in bootloader that can be used to updated firmware via USB / UART into the cc2531 stick or simply the cc2530 chip without using CCDebugger or Arduino.
But this requires not a conventional hex-firmware, but a special sbl-firmware (Serial Boot Loader).
For the normal firmware, the process of assembling it is described here https://github.com/Koenkk/Z-Stack-firmware/tree/master/coordinator/CC2531
And for SBL firmware, everything is the same, but the assembly CC2531-ProdSBL (or CC2530) is selected. In this case, not a hex file (680Kb) is generated, but a bin-file (234Kb).
And with one exception - it is necessary to specify MAKE_CRC_SHDW instead of FAKE_CRC_SHDW defined symbols.
This firmware must be flashed through SerialBootTool. It comes with IAR, or you can download it separately here http://processors.wiki.ti.com/index.php/File:SerialBootTool_1_3_2.zip
When starting SerialBootTool, you must select Zigbee family. Then select the SBL firmware (bin-file). And then select port and specify the parameters of the port where cc253* is connected.
After that, you need to re-insert the cc2531 stick or disconnect and reconnect the board with the cc2530 chip and click Load Image. Only in first minute after the connection is available bootloader mode!
The firmware will be executed and the chip can be used again.
