MPC5775E UART BOOTLOADER

[ajithjeanuvs]

Hi NXP Team,

I am working with the MPC5775E EVB and I would like to use a UART bootloader for firmware update. I am using S32 Power Architecture IDE. 

I would like to know:

1. Does MPC5775E have a built-in ROM bootloader that supports UART?

2. If yes:

   • Which UART module is used?

   • What pins are required?

   • How do we enter boot mode (boot configuration pins)?

3. If not:

   • Is there any NXP reference example or application note for implementing a custom UART bootloader?

4. Are there any example projects available in:

   • S32 Design Studio?

   • NXP SDK or application notes?

I have checked the reference manual but could not clearly find UART bootloader details.

Could someone please guide me on:

• Boot configuration (BOOTCFG pins)

• Required flash configuration

• Any example code or documentation

Thank and Regards,
A. Ajith Kumar

Hello,

Does MPC5775E have a built-in ROM bootloader that supports UART?

No, it does not.

Is there any NXP reference example or application note for implementing a custom UART bootloader?

Our examples are posted here, but no bootloader for UART:

Could someone please guide me on:

• Boot configuration (BOOTCFG pins)

• Required flash configuration

• Any example code or documentation

Have a look at this thread for bootloader examples:

That could give you a good overview.

Best regards,
