Is there a bootloader for K02 MCUs?

[atilla]

Using the MCUXpresso SDK builder, I asked for mcu-boot for my MK02FN64... chip. The interface says mcu-boot works for K22F board, but not for K02 processors.

The NXP bootloader web page says there is a "flashloader" available for K02 processors, available on-flash, but once it's overwritten, it's gone.

Is there a bootloader/flashloader I can download and write into my existing K02 based boards?

We need a permanent bootloader that will accept firmware updates from an external SPI master. Maybe modifying the flashloader to not self-destruct could be a useful option? Where can I find its source?

Hi,

You could also refer to the bootloader examples in the K02 SDK. Those examples are for FRM-K22F but you can take them as a reference.

You can download the SDK from the below link:

Best regards,

Thanks, it looks interesting, for using from a PC or network. My use case is a bit special (from an external SPI master). I will still look into your code, and maybe I can still make use of it for our purposes.
