Bootload from Ethernet on MPC5748G

[arribaconsultin]

Hello,

I'm looking to create a bootloader for the MPC5748G via Ethernet connection and was curious what previous development has been done with respect to this, if any, and see if anyone has resources that can point me towards the best path to achieve this.

The goal is to be able to push firmware to this board via ethernet and keep the device tucked away without needing to access it.

Whats the best way for me to go forward with this?

Thanks!

Hi,

There’s serial bootloader for MPC5748G:
https://www.nxp.com/docs/en/application-note/AN5319.pdf
https://www.nxp.com/docs/en/application-note-software/AN5319SW.zip

Ethernet driver can be found in SDK in S32 Design Studio IDE:

Hope this is a nice start point.

Regards,

Lukas

Hi Lucas,

The bootloader you created looks interesting. I wanted to use the Zip that you pointed above with the S32 studio for MPC5748G. Is there a way t do that ? Or even if you can help me understand the structure of the code like where can I make the project if i were to edit it to make it work on CAN/LIN instead of UART.

Thank you.

Hello, I am developing a can-based bootloader. May I ask if you can share your bootloader code for my reference? Thank you very much.
