Hi Lukas,

Could you provide me some sample application project for RAppID tool support?

I don’t understand how to add APPKEY, RCHW & __thumb_startup to my code exactly?

After downloading my S32K144 AP by RAppID tool successfully, application always doesn’t work well.

Thanks.

Hi Tony,

I'm afraid we the source code for rbf files could not be shared. 

What kind of customization are you looking for?

Hi Stan,

We wish that our device can stay in bootloader mode after pulling one GPIO & booting.

It will make sure to enter bootloader and doesn't mind the delay time.

Hi Lukas,

Could NXP provide source code about Rappid tool and SK144_Bootloader.rbf (as attached) ??

We need to add somethings for our products.

Hi,

there's an example in S32 Design Studio, so you can see there how it is implemented:

Hi Lukas,

Thanks for your response.  

I follow the sample to add APPKEY & RCHW to my code (attached). But I download app to S32K144 by RappID, the app still don't work. What else do I check?

Hi,

did you modify linker file appropriately? Area 0x0 - 0x1FFF is occupied by bootloader, so the linker file of application should be modified and everything should be shifted up above this address. From Rappid BL release notes:

Hi, 

The Start Address of my application is 0x2000. 

Check if my srecord (CAN_OBC.srec attached) contains correct data needed for rappid bootloader as below, but there is nothing about appkey & rchw in my app.

I follow the sample to build and why there is no appkey & RCHW in my application?

Hi,

how did you updated linker file? Did you added those two sections? I mean .appkey and .cfmConfigure. Attached you will find linker file from bootloader_S32K example.

Thanks, it works. I miss .appkey and .cfmConfigure in the linker file.
