Electronic – NXP QN9021 (ARM Cortex M0) programmer

armcortex-m0programmer

I have made a small breakout board with the QN9021 SOC (BLE + ARM Cortex M0). I am having trouble flashing the code into this device. Assuming that this device is wired properly and working fine, how do I program it?
None of the cheap OpenOCD debuggers seem to support it! and the commercial (JLink/ULink) are too costly for me.
Can I still use the unsupported debuggers somehow (mayne by manually adding the memory location map)? If so kindly tell me how to do so?

You can use QBlue ISP programmer using UART communication. You need a USB serial TTL convertor with 3.3V.
