MCXA UART ISP protocol / procedure

[Mateusz_K]

I want to implement host side of ISP communication for UART, MCXA142. I send Ping packet and receive expected response. What is the typical sequence of send and received packets? 

At the moments moment, mine looks like this: 

1. Send Ping

2. Receive Ping response

3. Send command packet in framing packet: erase all

4. No response

Hi Mateusz,

ISP protocol host is already implemented in Secure Provisioning SDK. This is open source python code. I'd recommend to reuse.
