How to start program when powered

[yann_munich]

Hi there,

I finally finished my program,  and now I want to save it on my FRDM k64f and  I want to start it automatically when powered.  I tried to use the Release version but it still not start.

It start when I give the command over J7-Link when debugging with MCU.

Must I use a SD card?

Thx in advance.

Hi,

You can check your ICF file.

"define symbol __ICFEDIT_intvec_start__     = __ICFEDIT_region_RAM_start__;" means run form ram address

"define symbol __ICFEDIT_intvec_start__ = __ICFEDIT_region_FLASH_start__;" means run from flash address

Hi,

I'm using JLink720000000. Where can I check if I programmed it to RAM address (Probably didn't do it)?

Thx in advance!

Hi，

Normally,the MCU will run form address 0x0 in flash when you reset after download the code into MCU  .

Which J-link command you used and have you checked if you have programed the code to ram address?
