Hi,
I have a Default-Application and a Bootloader-Application. Both are developped separately. The Bootloader-Application can load the Default-Application.
But prior to shipment of our product we want to store both the Bootloader-Application and the Default-Application in the uC.
My question is: how do I flash both applications in one go into the uC?
Thanks
Henk
You don't mention chip type or method of programming.
For factory-programming of LPC23xx we just combine the two hex files and then download that file using the primary bootloader available in the LPC23xx chips. If needed, we may also combine the hex file with a precompiled "configuration sector" that may give information about the board.
Per Westermark: Have you any further unformation on how to do this? Specially the part where you combine the HEX file with some precombiled "config sectore" (binary data)?

I just remove the last line from one hex file (it's an "end" record) and then concatenate the contents of the next hex file.
When using FlashMagic to send the combined file to the chip, I don't need to do anything else. Some programming equipment don't support hex files that don't have all memory regions sorted, in which case you may need to do more work - or maybe just make sure you combine the input files in the correct order.
In my case, I might glue boot loader (one hex file from separate build) + config sector (one hex file with retrieved or generated data) + application (one hex file from separate build) into a single hex file that the factory then programs into the device.
a classic tool to combine hex files is the "srecord" have a look at this srecord.sourceforge.net/ it runs on linux/win emvironment and it is easy to use
srec_cat The srec_cat program may be used to catenate (join) EPROM load files, or portions of EPROM load files, together. Because it understands all of the input and output formats, it can also be used to convert files from one format to another.
