I want to merge the EFM8LB1 bootloader and an application hex image file. Is there a tool available that can do this?
Yes. To do this, use Simplicity Commander to merge the hex files. Refer to UG162 for more information and detailed command options for the merge command.
Using the EFM8LB1 UART bootloader and blinky as an example (you can get these images in AN945SW), open the windows command console and input the command below:
commander convert EFM8LB1_RainbowBlinky.hex EFM8LB12F64E_QFP32.hex -o Merge_uart.hex
This will merge the two hex files together into a single hex file.
