Re: Lightning DCDC kit

Santosh,

I'm sorry for the issues that the DC/DC Lighting kit is causing you. 

I have seen that occasionally Windows has issues with particular FTDI chip IDs.  I would recommend for you to try reprogramming the FTDI chip's EEPROM.  See the following for instructions:

Thank you,

Hi Brett,

Thanks for the reply!

I tried the steps before but the problem is as it is mentioned that when we select scan option in M-prog instead of displaying "one blank device" it is displaying

"No blank devices found"  so what may be the problem?? Does FTDI chip got damaged or it is mal-functioning??

Best Regards,

Santosh.

Santosh,

Has this kit ever worked?  Or is this issue a recent problem?

Does [M2]-LD1 turn on when the USB cable is connected from the board to the computer?


Thank you,
Brett

Dear Brett,

As soon as we connect the USB cable the LD1 led will glow and we were able to see dual USB<->Serial converter in the device manager as shown in the attachment and if i start scanning in Mprog it shows Number of blank devices = 0, Number of programmed devices = 0;

So can you let me know what may be the issue??

Best Regards,

Santosh.

Hi Brett,

I installed the FTDI driver than the USB was getting detected in "DC/DC Lightning EVM" GUI but now the problem is it is showing "check the connections"

So I am trying to reprogram the controller  but I am getting problem as shown below while loading the code available in control suite from CCSv5,

"!ERROR: Build-tools C2000v5.2.6, or any version compatible with it, is not currently installed! Please migrate the project to one of the supported build-tools first."

So can you guide me to proceed further.

Best Regards,

Santosh.

Santosh,

In CCSv5, if you right-click on the project (from the Project Explorer window), you can then select the Compiler version that will be used to build the project.  Change it from v5.2.6 to whatever version has been installed on your computer.

If you have none, you may need to do a Code Composer update (Help->Check for Updates)


Thank you,
Brett

Hi Brett,

When compiling the code I am getting the error as shown in the attachment, Is this due to some memory issue??

Thanks!

Best Regards,

Santosh.

Santosh,

Last step (95% confident):

Delete the file: 28035_RAM_lnk.cmd from your project. 

(when you changed the compiler version, CCS automatically added in that .cmd file (which was not needed). The problem you are seeing is that the two .CMD files are defining conflicting memory maps)

Sorry for all the issues you've ran into with this project.  I just tried this with CCSv5.2.00069 on my machine and didn't run into these problems (although I've seen this before with previous versions of CCSv5).  On my machine, I already have the xds100 drivers working well and when the Code Generation Tools Compiler settings didn't match it threw a warning as opposed to an error.  What version of CCS do you have installed on your machine?


Thank you,
Brett

Dear Brett,

When I am trying to connect from the Lighting DC/DC GUI the USB is getting detected but it is showing " Please Ensure SCI Boot Jumper is placed or that the target is flashed than try it again" as shown in the attachment.

I loaded the same code provided in control suite by mounting the picolo board on my evk kit and than mounted it back on the lighting DC/DC kit.

So is there any problem

in the code or with the jumper settings as I placed jumpers properly as given in the manual.

Best Regards,

Santosh.

Santosh,

Based on this post and the previous post I am guessing that your goal was to reprogram the F28035 MCU via CCS and then demo this software with the GUI.  Correct?  Were you able to get the CCS project to work?

Notes:

1. I believe that when you were in CCS, you were using the RAM version of the project.  To actually have the project program the flash and be able to run immediately from boot up, the flash version of the program must be selected and programmed.  In CCS, if you right-click on the project name in the Project Explorer window, you can change the configuration from F28035_RAM to F28035_FLASH.  Once you load the FLASH project, CCS will automatically program the flash.
2. Make sure that all jumpers are in the correct position as stated in the GUI Quick Start Guide and that SW1 on the controlCARD is in the down position.
3. From your screenshot, it looks like you've correctly selected the comport that will be connected to the Lighting kit.  Click OK.  Now click "Connect" in the main GUI window.  The GUI should connect.

Thank you,
Brett

Hi Brett,

I am able to program the picolo card on my evaluation board and the USB port is getting detected properly on PC so the problem I suspected was with the JTAG connection

so I tested with "Test Connection" option in CCS and the scan test it shown failed so please find the attachment of the connection failure and suggest me to solve it.

I believe if it get solved we will be able to work on the kit easily.

Best Regards,

Santosh.

Santosh,

The GUI uses the UART (SCI) on the FTDI chip.  On this board, in order to have the C2000 controlCARD boot-from-flash, the JTAG must be disabled.  (ie [Main]-J6 should be removed).  Once this is done, the JTAG scan chain test should fail.

CCS uses the JTAG port.  In order to have CCS work, [Main]-J6 should be placed.  The JTAG scan chain test should pass under this circumstance.

I think this describes your experience.


Thank you,
Brett
