This is written in the "Read Me" file for a S12X bootloader example,
On the PC side, all that is needed is a simple terminal program like Hyperterminal. The terminal program needs to be set for 9600 baud, no parity, 1 start/stop bit and XOn/XOff handshaking. The bootloader uses SCI0 for communication with the PC.
After entering the "Program Flash" command at the prompt, the terminal's "Send Text File" capability should be used to send an S-Record file to the target S12X.
I write my own PC software using C++ Builder. I want to include the bootloder update in my software. What I do not understand is what communication protocol is used for the file transfer. Is it ZModem, Ymodem, Xmodem or some other method.
Also does any one have an example.
