Bootloader for Serial (UART) flashing of MC9S12xDP512

[santhoshsl]

Hello All,

we are using MC9S12xDP512 controller for our project. Currently we are using Softec and P&E tools to flash our .s19 files.

But we need to develop an UI or application for PC which communicated through UART to our controller and this Application will have options to read and write FLash or EEProm.

So can you please let me know if there are any bootloaders (open source) available for this flashing through UART.

Santhosh,

I've attached a CW Classic project for an S12XDP512 bootloader that I wrote a number of years ago. No guarantees, but the code is fairly well commented.

Best Regards,

Gordon

I hope it helps you.
