PN7462: Secondary Bootloader

[shiv_patil]

Hello Community

I am using the N10995. as a reference to the secondary bootloader.
I am using the MCU Expresso IDE for the development & this document is more related to the LPC Expresso IDE.
The settings described in the document are not found in the  MCU Expresso IDE. Will you please help me to get a document that is more specific to the PN7462?

Regards,
Shiv Patil.

Hi @shiv_patil ,

I am sorry, but there is no doc on this topic for PN7462, but the app note you are referring to should be ok with PN7462 ,and for questions regarding LPCXpresso and MCUXpresso settings ,you may check with https://community.nxp.com/t5/MCUXpresso-Software-and-Tools/ct-p/mcuxpresso .

Hope that helps,

Have a great day,
Kan

Hello @Kan_Li 

I am having some more queries related to the secondary bootloader implementation.

1. Should I compile & program the bootloader application standalone?
2. How Can I replace the application code with PN7462 CCID Example?
3. How Can I revert the Secondary Bootloader changes?

Will you please elaborate on this concept to understand me?

Regards,
Shiv Patil.

Hi @shiv_patil ,

1. Should I compile & program the bootloader application standalone? - It is similar as compile & program a normal user application such as CCID demo. Please kindly refer to "8. Managing the PN7462 family SW projects with MCUXpresso IDE" in UM10883 for more details.
2. How Can I replace the application code with PN7462 CCID Example? - Please refer to above for details.
3. How Can I revert the Secondary Bootloader changes? - The secondary bootloader is also some kind of user application, you may erase it and program with another application such as PN7462 CCID demo.

Hope that makes sense,

Have a great day,
Kan

Hello @Kan_Li 

I am referring to the N10995.
I have imported the secondary bootloader examples to the MCU Expresso.
Built the projects.
I am able to build the bootloader & CMSISv1p30_LPC11xx.

But,

While Building the application project, I am getting the following error.
Note: I haven't made any single change to the application project.

Will you please help me to debug this error?

Hi @shiv_patil ,

Actually I am not expertise with MCUXpresso IDE, but referring to the snapshot, looks like there is some lib missing, please kindly check the path settings something like below:
