TMS320F28027: How to know How many RAM and FLASH TMS320F28027 is take for our code?

Dave:
I can answer question 1, but I will leave the 2nd question to the JTAG experts...

In the \Debug (or \Release) directory, you should find a file associated with your project, with a .map suffix. In this file, you will find out how much flash and RAM is being used by the project.

Hopefully, that helps.

CCS also has a graphical tool called "Memory Allocation". Go to Window -> Show View -> Memory Allocation

2.I made my own board (NOT STICK CARD) .I am using TMDSHVMTRISPIN (HVkit) which has Isolated JTAG(I made a daughter board  for DIM100pin socket to get Isolated JTAG ) and I made my flat cable as short as possible,in addition I changed the speed of Jtag to 100khz to be able to work in noisy condition. but it will disconnect so easy.. as soon as I run my motor .:( 

Motor based applications do face this so called "frequent disconnection" issue. I would recommend to use an isolated USB adapter that would isolate your laptops/PCs USB port. You can also wind a ferrite core around the USB cable or use a ferrite USB cable.

I got confuse ... because it is  Isolated JTAG. it must not get any noise from USB to Microcontroller

It seems like the isolation is not enough then.

Dave,

Please check out this E2E thread concerning emualtion stability when running the motor; there are some best practices for the earth ground/shielding and so forth.

dear my friend thanks for recommendation

but I could not figure out about this charts would you please explain how to know total used RAM & FLASH ?

Thank a lot dear MatthewPate that was useful :)
Dave.

Thanks dear Todd Anderson
the only thing which I found related to FLASH was this bout I could not quite understand How to extract RAM & FLASH used from that .
Would you please explain it more?

Dave.

dear my friend.

my USB cable has ferrite core itself .in addition i could not find isolated USB adapter anywhere even in google !

Dave

length shows the amount in that entity, in you case 6000 is hex value translates to 24576, and you are using x4350, which is 17232 - roughly 70% full. A lot of the items you have NO control over, like IQTABLES.

If you have a lot of features to add, you may want to bump up to a higher capacity part...

Dave,
Wanted to reach out to see if this issue can be closed or if you have more feedback for myself or the others on the thread.

Best regards,
Matthew

dear Gautam Iyer,
I would be happy if you explain it more about memory Allocation chart
