Implementing your own code for flashing the QN902x over SPI would be time consuming. However, you can follow the description of the ISP protocol in the chapter <STRONG>4.4 ISP Protocol Description&nbsp;</STRONG>of the <A href="https://www.nxp.com/docs/en/user-guide/UM10995.pdf">QN9020 Software Developer’s Guide</A>.</P><P></P><P>Regards,</P></BODY></HTML> Thu, 19 Oct 2017 17:50:23 GMT https://community.nxp.com/t5/Wireless-MCU/QN902X-SPI-Bootloader/m-p/704508#M3589 gerardo_rodriguez 2017-10-19T17:50:23Z
