For my project I use the MK70FN1M0VMJ12 microcontroller. I tried to add a bootloader mode in order to program the microcontroller without using the JTAG probe.
Thanks to the NXP community, I found a bootloader which corresponds to my needs: https://community.freescale.com/docs/DOC-102616
A few days ago, I succeeded developing a program with KDS which can be loaded via the bootloader.
Now, I want to change my program because it needs some evolution. But after modifications, the soft does not start after in spite of a correct flash of the micro.
My procedure of compilation:
I modify the linker file (offset: 0x10000 on addresses)
I create a flash Image file Motorola S-record
I add “--srec-forceS3” for the compilation of the image
I change the name of the file in “image.s19” and I use it on a USB key.
I do not understand why the first program was Ok and now I cannot modify this.
Could you give me some advice?
Thank you in advance for your help.
