TIDA-01281: cold start memory map allocation

michael coletti

Part Number: TIDA-01281

Hi,

i tried to enable the cold start at the Firmware by un-comment the right sections as recoomened here: e2e.ti.com/.../746519

but after i done that i got this error:

after trying to debug it i saw that at the those function are not allocate at the memory map:

at the same map they reference twice:

can you please help me with that? and explain why those functions/symbol have to be allocate like that?

thank you

Hi, Michael

Have you included the coldstart.c and coldstart.h in your project?

and, you may check if you have clearly define those functions in your code?

Hi,

again, thank you very much for your support.

i found the problem, i forgot to remove the #if 0 on those function.

i did it, but now i can see other problem...

(those unidentified's are define at the main file )

Thank you

Hi, Micheal

I don't know how this happens.

But, you may define them as 'extern' variable by yourself.

Hi,

after that i define the 'extern' variables, i saw that FLASHA is completely full - so i changed the memory map (Linker Command File For F28033) for .econst - the new location is at FLASHF (since it is an empty section).

i am lilltle bit lack of experience, so i would like to ask if this action is ok, even thoge the progrem is now build.

Thank you

Hi, michael

If you only defined variable with 'extern', it should not take extra memory, because the variable should be existed in some other code file.

Your excution suppose is workable, you could refere to the following:

Hi,

I didnt have some of those variable defined at the the main file - so it did took some memory.

are you sure that i got the most updated FW?

maybe i got by accident a beta version of it.

Thanks
