Serial bootloder for K32L2B31VFM0A

[Nikunj]

Hello,

I'm using the target device as a K32L2B31VFM0A and the host device as an Nrf52840 microcontroller.

I want to perform an application firmware upgrade of the target device( K32L2B31VFM0A) from the host microcontroller (nRF52840).

I'm using only four pins for the serial bootloader.

LPUART0_RX             -Prot PTA1

LPUART0_TX             - Port PTA2

NMI_b (BOOTCFG0)   - Port PAT4

Reset                           -Port PTA20 

can you please give suggestions on how to do it?

hello,

I have to download the host application firmware file (blhost_2.6.2.zip) but this source is in.cpp, so can you provide source code in.c file.

thanks
