Boot source code to use RAppID Bootloader app with S32K144

lucianomoretti — Tue, 04 May 2021 21:31:28 GMT

I want to program a S32K144 with the RAppID Bootloader Utility but I'm having issues finding the code for the bootloader part that needs to be loaded into the Flash of the S32K144. The RAppID tool lists the S32K144 as a supported chip.

I've found the Unified Bootloader Framework download on the S32K page but my initial look at that it seems to only support CAN/LIN bus for updates.

Basically, I'm looking for the code for the S32K144 RBF so that we can customize it for our board to use LED indications, etc.

Hi,

Unfortunately, the source code of .rbf file is proprietary and is not available. But if you want to develop own solution, there are these two application notes which can be used as a nice starting point:

Thanks. Disappointing that the solutions seem so disjointed but that AN12218 serial bootloader looks close to what we're looking for.
