Hi,
I am wondering whether there is anything the the NXP bootloader that prevents the kw32w041 to boot up when I put low the GPIO5 before powering it up.
Any help is much appreciated.
Hi,
Hope you are doing well. The GPIO5 is also the ISP Entry pin:
[3] ISP programming mode: leave pin floating high during reset to avoid entering UART programming mode or hold it low to program
You can find this information in the Data Sheet.
Best Regards,
Ricardo
