Bootloader for Serial (UART) flashing of MC9S12xDP512

santhoshsl — Thu, 16 May 2013 12:10:59 GMT

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

In attachment you can find slightly modified Gordon’s bootloader include short introduction, conversion tool and demo application.

I hope it helps you.
