If you set the P2_9/P2_8/P1_2/P1_1 as low/high/low/high, if you enter ISP mode by setting P2_7 as low during/after Reset, can you see the disk driver after you insert the USB0?</P><P>Anyway, I suggest you download the latest Flash Magic tools from the link:</P><P><A href="https://flash-magic.informer.com/download/#downloading" target="_blank">https://flash-magic.informer.com/download/#downloading</A></P><P>The tools can detect the USB automatically, pls try to download application code via USB with the tools.</P><P>Hope it can help you</P><P>BR</P><P>XiangJun Rong</P><P>&nbsp;</P> Tue, 15 Sep 2020 07:40:22 GMT https://community.nxp.com/t5/LPC-Microcontrollers/LPC1837-Boot-ROM-mode/m-p/1153301#M42235 xiangjun_rong 2020-09-15T07:40:22Z
