The only way I found to clear them was to erase the complete flash including the bootloader. Is there any possibility to clear them, without erasing the bootloader?</P><P>If not, I think it should be possible to reprogram the <A href="https://community.nxp.com/t5/tag/bootloader/tg-p">#bootloader</A> again. But I do not have the HEX-file for the bootloader. Is it possible to download it somewhere? Or is there a way to read it from a working second chip?</P><P>Any help is welcome.
