Sending a binary file / intel hex file over UART

saipriyasubrama — Thu, 15 Mar 2018 16:22:53 GMT

I am using the KV series of Kinetis microcontrollers to send a .bin file over UART to program another microcontroller. I would like to know if there is any sample code that guides me in the right direction to do this. I do not know how to include the .bin file into the application code for the Kinetis. I am using KDS and PE for this purpose. Is there a sample code online for me to look at?

Hi,

You can check the steps mention in the following document about merging applications using the linker commands for more information about including a bin file to your application:

I am trying to use the intelhex file of an application to be used on another target microcontroller. Meaning i have divided the memory in the target microcontroller into Bootloader Section and application section.I am trying to pass the hex file generated for the application from the host to the target microcontroller using UART. Host is the Kinetis KV micro.

I am not able to use the "fopen" command on KDS to open my intel hex file and save it into 8 bit buffers and transmit it to the target for coding in the application area. Is there a way to transmit intel hex files through UARt for transmission and coding on another microcontroller?
