UART SERIAL BOOTLOADER FOR K32L2B31VFM0A
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
Question 1: can you provide entry boot sequance using boot config pin?
Question 2: can you please give suggestions on how to do it?
Question 3: 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.?
Question 4: As per attached screen shot write memory command howmany byte write at a time?,can you provide TX and RX frame format of memory command(in documment example generic frame format not match)?
Question 5: data command support 32byte only,we are using UART periphiral can we increse data packet byte length.?
Question 6: Firmware upgrade resume possible? can you provide step?
Question 7: How to know host device application file write is ok ..App CRC command is supported for this controller?
