Hi Sal,

Thanks for your reply

We read document which you shared. We are planning to start with code composer studio, So could you please suggest us more about start on Code composer studio.

Thanks & regards,

Hi Sal,

We are flashing kernel and our application code using  f05_DownloadImage.cpp code.  Here we are able to load kernel to our controller but we are unable to load application code to it can you please suggest what might be the issue ?

Thanks & regards,

Jyoti

Hi Sal,

Can we do same with Code composer studio (without help of MS visual studio) ?

We found the MS Visual Studio project file on C2000 kit but we didn't find for code composer studio.Can you please suggest where can we get this CCS project file?

Thanks & regards,

Jyoti

Hi sal,

We tested binary code which was given by you (kernel,application code and executable for serial flash programer for LEDBlink example) and it was not working on our custom board.

Here I attached screenshot which contains logs and you can see it stops at while downloading application image and does not come out from that loop.

Please provide resolution for the same.

Thanks & regards,

Jyoti

Hi Sal,

Can you please flash our appliaction file on your f2833x control card let us know wheather you are able to flash to  your controller card not. We are facing issue while flashing the below code to our board.

I have attach 2 application file and serial flash path given below

1. File name : PQCR_DAC_1.5V.out

C:\ti\c2000\C2000Ware_1_00_06_00\utilities\flash_programmers\serial_flash_programmer>serial_flash_programmer.exe -d f2803x -k kernel.txt -a PQCR_DAC_1.5V.txt -p COM5 -b 9600 -v 

2. File name : PQCR_DAC_3V.out

C:\ti\c2000\C2000Ware_1_00_06_00\utilities\flash_programmers\serial_flash_programmer>serial_flash_programmer.exe -d f2803x -k kernel.txt -a PQCR_DAC_3V.txt -p COM5 -b 9600 -v 

Please let us know if you are able to flash or not.

Thanks & regards,

Jyoti

Hi Sal,

Did you check flashing our aplication code on your board ?

We need your help to fix issue on our project.So now we are debugging same code and we are able to load kernel to controller but we are facing issue while flashing application code to controller. 

On above we can write appliaction code to com port file but while we are trying to read same from com port file it stuck and control not going further. Can you please suggest us what might be the issue ?

Thanks & regards,

Jyoti 

Hi Sal,

As you suggested that add delay after serial flash programer after sending header file information, We tried adding multiple delays but no luck.

For your reference please check below screenshot.

Can you please suggest what might be the issue ?

Thanks & regards,

f05_DownloadImage_new.cppHi sal,

We are using F28335 but as you suggested we are passing argument as f2803x.

we made the one kernel project and one application project as integrated is not working.

 First we try to run the kernel code in visual studio and reset the hardware.  It seems kernel code is loading.

Then run the application code in visual studio only  then control is coming back to main from following code.

if (checksum != (rcvData | (rcvDataH << 8)))

return(12);

else

checksum = 0;

here rcvData is 8 and rcvDataH is 0 hence condition is not matching and control return back to main and not loading application file at all.

We have also added delay but it did not helped for us.

I have some query as

1) after karnel load reset is required or not?

2)for f2803x we didnt find any erase function,  so erase is not required in the code?

3) what is difference between rcvData and rcvDataH?

4) Can you please provide whole project file for f28335?

Attached the copy of project file. please look into this and let us know the issue.

Thanks,

Jyoti

f05_DownloadImage(1).cppHi Sal,

Today i installed the controlSuit 4.9 and as suggested in datasheet of Serial Flash Programming of C2000™ Microcontrollers i started work on serial flash programmer folder in visual studio.

I observed kernel was loading successfully.

I am getting error while matching application autobaud.

In that i found sendData and rcvData were not matching.

I tried with different baud rate, i observed different values for rcvData.

I was trying to send 'A' in return i was getting  31, 0,172 values for different baud rate

I tried adding delay from 10Sec to 1Min after loading the kernel but i am not succeeded.

I tried one thing. When i added below lines of code in kernel after sending each char, application autobaud successful occurs.

               dwRead = 0;

while (dwRead == 0)

{

ReadFile(file, &rcvData, 1, &dwRead, NULL);

Sleep(1);

}

printf(("==%lx\n"), rcvData);  

But later i am sticking at ReadFile(file, &rcvDataH, 1, &dwRead, NULL);   in below loop.

    while (dwRead == 0)

{

   #ifdef __linux__

    readf = read(fd,&buf,1);

       if(readf == -1)

       {

        QUIETPRINT(_T("Error %s\n"), strerror(errno));

       }

       dwRead = readf;

       rcvDataH = buf[0];

#else

ReadFile(file, &rcvDataH, 1, &dwRead, NULL);

Sleep(50);

   #endif

}

Can you please suggest us something to resolve this issue.

1) After adding read function while loading the kernel why autobaud was succcessfull for application?

2)Why the control is sticking at ReadFile(file, &rcvDataH, 1, &dwRead, NULL);  in above code?

3) Why we need to modify the project for F28335  as you said it will work directly ?

3)Can you please provide the project file for F28335.  

We are using F28335 but as you suggested we are passing argument as f2803x.

Attache f05_DownloadImage(1).cpp file. can you please look into this code.

Thanks,

Jyoti

Hi Sal,

serial_flash_programmer.exe -d f2833x -v -k f28335_flash_kernel.txt -a Example_2833xLEDBlink.txt -p COM13

As you suggest command line to use  f2833x as device id but for our project we are using f2803x  because our project doesn't support f2833x device.So If you have project that support f2833x device please share with us.

Q . Can you please tell us which gpio pin are you using for this LEDBlinking example ?

Thanks & regards,

Jyoti

Dear Sal,

 we are having 2 application files(1.txt and 2.txt). Out of which we are able to load 1.txt application file but unable to load 2.txt. Can you please suggest us what might be the problem. Both files are of same size but very small change in the content. Attached the both application files for your reference.

5123.1.txt6175.2.txt

Thanks,

Jyoti

We have got another issue while downloading application images using “serial_flash_programmer.exe”.

We are able to download our own sample code generated from CCS4.

We are also able to download some of the provided .out file, after converting them to hex. These files are converted from “*.out”  to “*.txt” using CCS8 provided tool “hex2000.exe”.

Issue:

Some of the “*.out” files are not downloading, stops after application Auto baud successful. It does not come out from the loop.

We would like know the reason , why some of the application hex files are not successfully downloading  while others are downloading?

Please help us on priority to resolve this issue.

Thank you,

A debug example for the line ending issue that Sal mentioned: e2e.ti.com/.../2902135

We are also able to download some of the provided .out file, after converting them to hex. These files are converted from “*.out”  to “*.txt” using CCS8 provided tool “hex2000.exe”.

Issue:

Some of the “*.out” files are not downloading, stops after application Auto baud successful. It does not come out from the loop.

We would like know the reason , why some of the application hex files are not successfully downloading  while others are downloading?

PFA : working & not working Application image files.

we have tested on Windows 10 & 7 Operating systems . we are not opening converted .txt files with Notepad to avoid any issues with appending characters.

Request you to please check at your end priority and provide resolution.

Awaiting for your reply

Hi, Vamsi & Sal,

We are using standalone application images. We are converting from ".out" to ".txt" using below command
(hex2000.exe -boot -sci8 -a -o application.txt application.out)

and then flashing using "serial_flash_programmer.exe",using below arguments :
(serial_flash_programmer.exe -d f2803x -k kernel.txt -a application.txt -p COM3 -b 9600 -v)

we are generating.out files from project default rebuild option

Attached : cmd linker file.(file extension is changed to .txt)
Attached Images : working & Not working

Attached .out files    : working & not working
Attached .txt Files : working & Not Working

Awaiting for your quick resolution.8524.Application_Image_Working.txt1234.Application_Image_Not_working.txt

Thank you

Regards,
Bhanu

Hi Bhanu,

thanks, just for clarification for our team:

- you use the same linker.cmd for both .out files?

- you build and convert files on Windows machines?

- What is causing the change in .out file (#define changes, manual edit,...)?

Just trying to understand what could cause this as the resulting .txt only have minor differences in some bytes. I assume you tried that multiple times on multiple boards? Also in different orders?

Do you have more working/non-working examples using other source code or build options?

Best regards,

Frank

Hi, Frank,

Please find below information :

- you use the same linker.cmd for both .out files?

(Yes...we use same linker file)

- you build and convert files on Windows machines?

(Yes. we use windows 10 environment)

- What is causing the change in .out file (#define changes, manual edit,...)?

(change in some variables which are sent via SPI to configure DAC )

Check the attached image shows what changes made it working & not working.

-Just trying to understand what could cause this as the resulting .txt only have minor differences in some bytes. I assume you tried that multiple times on multiple boards? Also in different orders?

(yes..we have tried on two boards multiple times)

We have tried with your recommended changes ,added below line .

(SciaRegs.SCIHBAUD = 1;)

It did not resolve the issue,

FYI: attaching "SCI_Boot.c" file here.

Please check and let us know if any other changes will be recommended by you.

Awaiting for your reply.

Regards,

Bhanu

Hi Jyoti,

I have checked your SCI_Boot.c file.

You made the following change:

//
// Must prime baud register with >= 1
//
SciaRegs.SCILBAUD = 1;
SciaRegs.SCIHBAUD = 1; //this line is recommended by TI

There is a small mistake in the file. TI recommended to make HBAUD = 0 not HBAUD = 1.

Please check the post from Sal.

As Sal mentioned please modify it as

//
// Must prime baud register with >= 1
//
SciaRegs.SCILBAUD.bit.BAUD = 1;

SciaRegs.SCIHBAUD.bit.BAUD = 0; //ADD THIS LINE OF CODE

With this change rebuild the kernel and regenerate the hex file for the kernel.

Thanks,

Katta

DSP2833x_Sci.hHi Sal & Katta,

Not working as you have suggested.

We have tested below lines as you have mentioned with some minor change, because exact line gives compilation error as attached in the screenshot.

Also we are using "DSP2833x_Sci.h" header file. Here I am attaching for your reference.

//

   // Must prime baud register with >= 1

   //

   //SciaRegs.SCILBAUD = 1;

   SciaRegs.SCILBAUD = 1;

   SciaRegs.SCIHBAUD = 0;   // added this line recommended by TI

   //

   // Prepare for autobaud detection. Set the CDC bit to enable autobaud

   // detection and clear the ABD bit

   //

Please check and provide solution.

Thank you,

0216.Application_Image_Working.txt6153.Application_Image_Not_working.txtSerial_Data_Capture_Working_NotWorking.zipHi Sal & Katta

In addition to  above reply we have some more observation's while downloading through USB UART serial port.

We are debugging this issue with serial port analyzer on the host side while downloading to board, to verify the exact sequence of download steps.

PFA        : Working & Not working files , serial data captured for your reference.

                Also attached working & not working(.txt) files for your reference.

Observations :

1. Captured multiple times with Not working file.

a. It always stops at same particular location while downloading application image. (order Sequence no: 104491)

b. It is receiving 2 bytes of data (i.e checksum), after sending every block (mostly 4094 bytes) of application image,

c. We do not receive checksum after last block is sent (stopped at order sequence : 104491). It is received in working file

2. We see there are only 3 bytes of code changes in working & not working files.

a. These changes falls in the area where last block of not working files, which we do not receive checksum.

Why we are not receiving the checksum, what could be the reason.? (we have observed that it stops downloading after around 70% is done)

Regards,

Bhanu

Kernel_Header.zipHi Sal,

we have tested with your shared Kernel  file & serial_flash_programmer  and we found same observation with these files as well.

Actually we are using TMS320F28334 MCU, I assume you are testing on different MCU..i.e 28335.

we are requesting you to please check on the exact part we are using.

I am attaching the Flash kernel and header file used to generate the same.

1. Why checksum is not received from the MCU with not working file ?

2. Why 2 bytes of change at 6 places is causing above scenario ?

Attaching comparison screenshot images also for your reference.

Regards,

Bhanu
