F28M35XX ISO controlCard release 1.0 and 2.0 difference?

Hi,

After connecting to CCS, can you look at the memory content in RAM or Flash locations via memory watch window in CCS and check if you are able to read (read and write for RAMs) them properly.

Hi Joshua,

If you take a look at the last page of the F28M35x schematics you'll find the changes that were made.  Unfortunately, I don't see much change and what is there doesn't lead me to suggest this is the full problem.
\controlSUITE\development_kits\~controlCARDs\CCF28M35xxHWdevPkg_v2\R_PWB_RevD\

I have a few other thoughts:
1) The chip is locked.  I believe this is where Vivek was going with his question.  Basically you try to connect to the device like you are and then use CCS to open up a memory window.  You then try to write/read RAM and see if you can do this successfully.  Address 0x2000 0000 is where RAMC0 begins.
2) There is some other difference between your R1 board and your R2 cCARD.  One thought may be a difference in F28M35x chip revision.  On the chip's second line you should see something like YFB-*******.  The red bolded symbol tells you the chip revision number.  For example this is revB silicon.  (if there is no symbol then it is Rev0).  What is the rev on your two cCARDs? 

If this is where you are I'd recommend:
a) trying to put the device in boot-from-Ethernet mode - put in SW1 in Up, Up, Down, Down position and try again.  Boot-from-Ethernet mode will prevent the device from booting from flash and if the device is empty which can occasionally lead to issues.
b) make sure that you are using an updated version of CCS.

Hopefully this will get us closer to the problem. 


Thank you,

Hi Brett,

The latest problems have been solved but now I'm trying to load the Sine FFT demo and I'm running into problems. I've been following the steps and when I get to step 2 of the Crosshair GUI setup I receive an error. I have tried to connect through static IP address. When I click connect the  error I receive is " unable to connect to selected target, please verify that the target is available and ready to receive connections".

Thank you,

Hi Josh,

I am not very familiar with this project specifically, but I do see the following threads that may help you move further along:

http://e2e.ti.com/support/microcontrollers/c2000/f/171/p/178251/641836
(especially this one because I believe that you've rebuilt the project in CCS)

http://e2e.ti.com/support/microcontrollers/c2000/f/171/t/156349

Hopefully this helps. If you still have issues, I have a question: Does this project work correctly on the old cCARD (and you're only having troubles with this on the new cCARD)?


Thank you,
Brett

Hi Brett,

I'm still haveing troubles with the board. I am able to load and run the code for both the C28 and M3 but when I try and ping the device I get no response.  I attached the program that im trying to run. This program works on my old cCard (release 1.0 and ccs v5) but not the new one (release 2.0 and ccs v6). The reason I need the new one to work is that some of the GPIO on the old board doesnt work. Im trying to finish up my masters and Im trying to get this done as soon as possible and this is delaying me alot.  

Thanks for the help,

Joshua

Hi Joshua,

The crosshair GUI is no longer available for F28m35x device which means you may have to create your own GUI. The reason for this is you need to recompile and configure the crosshair GUI to get the variable addresses from the embedded system. This means you may have to create your own GUI that has a TCP/IP or UDP capability.

As for other Ethernet examples, please look at the enet_uip or enet_lwip. They both use the Internet explorer to communicate with the F28m35x  board.

Thanks

Hi Noah,

Thanks for the reply, could you point me in the right direction for which specific type of example you are talking about. Also if you could instruct me as to where the modifications need to be made that would be great.

As for the last question I'm still not sure about the loading of the C28. The erasing of the C28 doesn't occur when I try to load the program.  I think this is why the error is coming up.

Thanks for the help,

Hi Noah and Brett,

 I fixed the problem with the importing of the setup_m3 file but now I have encountered two new problems. I first uninstalled both controlsuite and CCS, then downloaded and installed controlsuite and checked for updates. Then downloaded and installed CCS and checked for updates. The first problem occurred when I tried to install the updates for CCS. You can see below the error messages. The next problem was with the loading of the C28. M3 loaded fine but C28 received the error shown below.    

(1)    Problem during installing updates:

‘Computing size’ has encountered a problem.

An internal error occurred during: ‘Computing size’.

Detail:

An internal error occurred during: ‘Computing size’.

Profile epp.package.cpp is marked as changed.

(2)    Problem with loading C28 project (for SW1: up, down,down,down and SW1:up, up, down, down)

C:\ti\controlSUITE\device_support\f28m35x\v205\F28M35x_examples_Control\blinky\c28\ccs\Flash\blinky_c28.out: a data verification error occurred, file load failed.

The message in “Console”

 I hope you can find the time to help me out, and thanks for all the help.
