Hello, I have to create a bootloader on a luminary micro. To start, I have just written a little program with a timer and at the end of the timer it branches to the start line of an other program stored in the flash before. So the second program starts but it is an RTX program and it crashes at os_sys_init (init); function. It seems that memory map with vector interruptions not working correctly. Is someone can explain me how to link correctly these 2 programs and how remap IT vectors? Thanks a lot Ludovic
you did not specify the device you are using. if you are using an LPC24xx device, place
RAM_INTVEC REMAP RAM_MODE
in the define of the ASM tab of your application (NOT bootloader) project settings. If you are using a CM3 device, use the
NVIC_SetVectorTable(NVIC_VectTab_FLASH, USER_FLASH_START);
statement instead.
Thank you for your help but I work on a luminary microcontroller. I don't know how to remap my vector interrupts table Regards, Ludovic
You are still avoiding to mention what processor you are using. A brand isn't enough, if that manufacturer have more than one processor in the model program.
The $1000 question: Have you checked the documentation for the processor?
