K8x OTA Firmware Update

I'd like some ideas on how to achieve Over-The-Air Firmware Updates on the K8x family.  My board has plenty of QSPI flash and an i2c connection with a 4G LTE comms module.   The comms module can forward a binary firmware image as a packet steam, but is too under-resourced to store the entire image, or to implement a bootloader host.

 

For performance reasons, the K8x's main application should run from internal program flash.
