Hello all,

I'am working on a project based on the controller tm4c129encpdt . in this project both serial bootloader and hibernation feature is needed . the problem is that when i trying to change rest vector address(0x4000) as needed for serial bootloader , after changing the address device enters in to hibernation properly but after waking up the programme doesn't continues to run.

if any one familiar with this issue please help;

thank u

Hello Diljith,

If you are using the serial boot loader from TivaWare then all you need to do is edit the linker .cmd file for your application to set the start address to 0x4000. See examples such as boot_demo1 and boot_demo2 which have their linker .cmd files adjusted in that way.

If that doesn't help, can you clarify if you are using TI-RTOS with this? I am not familiar with those xdc.useModule commands and I see that you are using that with ti.sysbios. But if those are just to set the reset vector address then forgo those API's and modify the linker command file.

Thank you Ralph

if we are only changing the app base at linker file it will not work in ti rtos programmes .need to change the reset vector address in the cfg file other wise it will not compile.

Hello Diljith,

Can you give details on what is happening when it comes out of hibernation? Where is it at? What is your expectation on what should happen?

Note: TI-RTOS for TM4C does not have any low power module support.
